Maxi-Cosi Zelia™ Pro 5-in-1 Modular Travel System in Caspian Caviar

[This review was collected as part of a promotion.] When I received the travel system, I was surprised at how light the box was overall knowing it contained an entire system! Unpacking and putting it together was easy peasy, nothing that required two people or any heavy lifting! First impression of the car seat— it was plush! Soft & comfortable! Nothing about it feels plastic-y or cheap! Love the vegan leather brown accents on the handles! My infant was calm and cozy in both the car seat and bassinet! The stroller fit incredibly well in my trunk space. It unfolds a little different than the typical stroller, be prepared when you go to open it! Love that it comes with a cup holder and a separate purchase isn’t necessary. The ease of clipping the car seat into the stroller or switching to the seat and bassinet combo was very loved. Having the design of the seat and bassinet in one is amazingly better than solo pieces. The breathable fabric and venting on the seat are also great for my infant who runs hot and becomes easily fussy when her temp isn’t controlled. My 2 year old also fit incredibly well in the stroller as a seat! This system will work great even beyond the use of the car seat! My kiddo is tall and fit with ease! Our go to modes were clipping the car seat directly in facing in either direction as sometimes we wanted to face baby and other times wanted her to be able to enjoy the environment! Second fav, the bassinet! And still loved the full seat as well! I was given this travel system to try as part of the Stellar Product Testing Panel.

[This review was collected as part of a promotion.] I received this travel system from the Stellar Product Testing Panel. I am absolutely obsessed with the Maxi Cosi Zelia Pro Travel System! I chose this system for my five month old and wish I found it sooner! I was tired of our previous car seat (different brand) and ready for a much needed upgrade. The Zelia Pro is so versatile and an excellent choice from the newborn stage on as you can use the stroller well into the toddler years (up to 39” and 50lbs). The car seat install is the easiest I have tackled yet and as a mom of five, that’s saying something. I have switched the base between vehicles in under 3 minutes on multiple occasions with zero frustration. The car seat (recommended 4lbs - 30lbs, up to 32”) is fairly lightweight and appears luxurious. It is made with ClimaFlow shell technology to keep your little one cool and features a zip-extend MaxShade canopy to provide shade and UV protection (UPF 50). All car seat fabrics are machine washable and dryer safe which makes cleaning messes a breeze. My little one was immediately content in the car seat and always appears comfortable, often enjoying naps on the go. I love the mesh panel on the side of the canopy that allows me to easily check in. The stroller features five modes - parent and world facing carriage, parent and world facing stroller (insert and harness covers are machine washable) and car seat caddy. I find myself using the car seat caddy the most at this stage and love how convenient the transition is from my vehicle. We have used the stroller everywhere (including the park) and love it. The wheels are larger which makes maneuvering a breeze (even through grass) and there is plenty of storage room underneath. There is also a cup holder that snaps on which is an absolute necessity for those of us that run of caffeine. The stroller easily folds in half and fits well in my trunk. Set up and break down is super quick. Overall this system is very high quality, convenient and easy to clean. Highly recommend!

[This review was collected as part of a promotion.] Thanks to the Stellar Product Testing Panel for providing me with this travel system. I was super excited to receive the travel system because we have one travel system already that we use in my car (car seat base in my car and stroller stays in my car) and we wanted another one for my husband’s car. I do really like the look of this travel system. It’s very sleek and looks classy and well made with good quality material. I really like the stroller of this travel system, however, I found the car seat base to be difficult to install, leaving me to feel unconfident that it was safely installed. I tried for a whole hour to install it based on the instructions provided as well as videos I found online showing how to install it into the seat of the car. I couldn’t get the base to be as level as I want it to feel confident that it is safe for my baby. I do find this super disappointing because the look of the car seat and the travel system is very nice. I don’t feel like I was installing it wrong; it is possible, but I will say that the car seat we currently have has a base that is much easier to install and makes me feel super confident that it’s safe due to the loadbearing leg that it has. So maybe if this base had a loadbearing leg, it would provide stability and therefore confidence in the safety of the car seat. The stroller was great – it has a smooth ride, and my baby seemed to be very comfortable in it. I love how much room is in the bottom of the stroller. It’s decently lightweight but still feels nice and sturdy and safe for my baby. I also want to note that the stroller was very easy to put together. It took me about 15 minutes to assemble the stroller. Again, I absolutely love the look of this travel system. It has a very sophisticated and classy look about it. However, the stability of the car seat base seems to have room for improvement. Also, I want to note that I used the stroller mostly in modes of car seat caddy and world facing stroller. These are the two modes that I find to be most useful when considering a travel system stroller, so the fact that this stroller allows for both of these easily was impressive to me.

[This review was collected as part of a promotion.] Hello! I'd like to begin by mentioning that I received this product as part of the Stellar Product Testing Panel, so this review will be free of bias. My partner and I are first time parents and have been using the Maxi Cosi Zelia Pro for the past month. Here are some key points. Impression - After using the stroller a few times with our 4-5 month old, there were some immediate differences that stood out from other brands. Most notably, the cushion lining the stroller is very soft and feels comfortable as well as being made from recycled fabrics. The bottom storage space is larger than other brands, and may accommodate larger diaper bags etc. There is no smaller storage compartments, so your special items like phone/keys/easy access toys would find better home inside the diaper bag. Unfortunately for us, our diaper bag is a small-backpack shape, so we could not get the full use of the bottom storage. It seems like it would be great while shopping too! Fits a lot. The wheels are larger, and feel smoother to use. The cup holder is nicer than other strollers that seem to have a frail grip. Super easy to assemble, pop on the wheels, cup holder, and the most difficult part is putting on the sun shade. For some reason we could not figure out how it properly goes, but I assume you're supposed to thread it along the zipper attached to the stroller. A bit confusing there. Folding is easy! Remove the seat, pull up the sliding grip on both sides, pull up with the convenient handle in the middle. If you are taller, the handle can extend by 2 or 3 inches. The baby seat, as far as I can tell, cannot be moved closer or further away from you like I have seen on some stroller models. This travel system is convenient because you can convert from seat to bassinet style for those younger little ones. Our little guy loves smiling at us, and when turned around to smile at others. He fell asleep pretty quickly in the stroller as well, though the brake was loud enough to startle him awake (- points here) I also pinched my hand adjusting the level of the stroller seat between the adjuster. Not too bad, but stung for a bit and left a mark. (- points there). It is wider than other strollers, so while it is nice for a stroll in the park, there might be some difficulty navigating smaller boutiques/antique stores; I did feel like I was taking up a lot of space inside at our local burger spot; cup holder was clutch though! The bassinet style cannot be adjusted, so our baby with reflux was either up or down. Another one we have used, has had an adjustable angle from the back to raise baby up slightly. Baby car seat feels thick, but not bulky (soft) Rear facing limits: 4-30lbs, and 32 inches limit for those wondering. Latch system is awesome for cars that have it, measured on our home scale, it weighs about 9.4lbs. Trust me, it is important to consider this weight when picking a new baby car seat. Our first one weighed about 17lbs, for my partner this was a lot of weight to carry after giving birth, so it was mainly my job as dad to take baby out of the car. 17lbs + our baby's weight got to be quite heavy, so 9.4lbs is not bad! Consider if your baby gets too heavy, you can carry the stroller in the trunk anyways! The design is very sleek - black with a little touch of tan. Overall - it is a very strong pick if you like all the positives, and it fits your lifestyle! It definitely has a nice look to it, feels comfy, and has a great cupholder.

[This review was collected as part of a promotion.] I was given this travel system to try as part of the Stellar Product Testing Panel. My overall impression of this travel system is really good. It’s super convenient and easy to use, especially when switching between the car seat and stroller. It makes going out with my baby a lot less stressful. The fabrics feel soft and cozy, and the design is nice and lightweight. My little one seems very comfortable and relaxed both in the stroller and the car seat. I like that it has 5 different modes because it gives me options as my baby grows. Right now, I mostly use the car seat attached to the stroller since it’s quick and easy. What I like most is how simple and practical it is. It saves time, feels comfortable for my baby, and is easy to carry and move around.

[This review was collected as part of a promotion.] Overall, I’ve really liked the Maxi Cosi Zelia Pro Travel System. It feels very practical for everyday use and not overly bulky like some other systems. It’s been super convenient going from car seat to stroller without a lot of effort, which is huge when you’re juggling a baby and everything else. The fabric feels really soft and cozy, which I honestly noticed right away. It doesn’t feel cheap at all. The lightweight design is probably my favorite part though. It’s easy to lift in and out of the car and doesn’t feel like a workout every time I use it. My baby seems really comfortable in both the car seat and stroller and will actually sit in it without fussing, which says a lot. The 5 modes are a nice feature and make it feel like you’re getting a lot of use out of one system. Right now I mostly use the car seat clicked into the stroller since it’s just the easiest for quick trips. I can see myself using the regular stroller seat more as my baby gets older though. What I like most is how lightweight and easy it is to use. It feels like it was designed for real life, not just looks. It’s simple, comfortable, and doesn’t overcomplicate things, which is exactly what I needed.

[This review was collected as part of a promotion.] I absolutely loved this travel system, from the color of the product to the smooth glide the stroller has! Not only that, it is also very light weight & decently compact. I drive an escalade & it fits just perfect. One of my favorite features of this travel system is the fact that the stroller seat has an extended canopy shade which is great for keeping sun out of my babies eyes. The car seat also has an extended canopy shade. I received this product as part of the stellar product testing panel & extremely delighted overall. The fabric is also very cozy feeling for my little one & he also seems very content overall being in the stroller & car seat compared to others we have had before receiving this one. It’s very convenient to change between the modes. Another favorite feature this travel system has, is the adjustable handle especially with me being 5’2 & fiancé being 6’2. It makes quite the difference!

[This review was collected as part of a promotion.] I received this travel system from the Stellar Product Testing Panel. So let’s start off with set up. Set up was pretty simple. I would consider myself a novice when it comes to putting stuff together. Most of the time I get lost at the first step. Oopsie. I didn’t even need to read the instructions. A few clicks and it’s put together. The stroller basically already comes put together. I still ended up checking my work with the manual to be safe. I like how quickly I can switch the mode for the stroller. Currently my baby loves the flat mode so he can catch come extra sleep while out and about. The fabric isn’t rough it’s suitable for babies. The ride is smooth and it’s good for walking on sidewalks or light gravel. I did have a hard time trying to break the stroller down but that was because I was trying to see if I could figure it out on my own. Which ,again, I am a novice when it comes to set up/ break down. Once I pulled out the manual it explained it very well how to break down. The infant seat is super snug and cozy. It is a bit on the heavy side. But the fabric is soft and I can tell it keeps baby cool. The color is neutral and goes with almost any outfit I wear, which is a plus for me! All in all I love this stroller set. The versatility that I get with the stroller is amazing. I can use it for my newborn or my toddlers.

[This review was collected as part of a promotion.] Amazing travel system combo! Thank you to stellar product testing panel for considering me to test this product. The stroller itself is smooth and easy to fold and I love that It comes with a cup holder and large storage underneath. The car seat as of right now I have no complaints I’ve only used twice but it’s very lightweight and nice that it’s compatible to attach to the stroller which I find convenient for fast errands or when my baby is sleeping instead of waking them up to transfer them to a separate stroller. I do wish the car seat comes with a base that has a leg for extra safety protection but that’s just me nitpicking, other than that this travel system is pretty convenient and reliable and the price point for a good brand is really reasonable!

[This review was collected as part of a promotion.] The Maxi Cosi Zelia Pro Travel System is pretty user intuitive as far as set up. It was easy to assemble and get a feel for the set up. The fold has its pros compared to other strollers such as fold up more compact and fold up smaller than some, but it does take some getting used to. My daughter loved the seat and I liked that the seat also doubles as a bassinet/cot. Being able to lay her flat and change her easily is a huge plus as we are often on the go and not always near a restroom with changing table. The car seat is comfortable and easy to carry and the made installation was fairly straightforward. The look and materials are very nice and compare well to other systems I have purchased at double the price point. The Maxi Cosi Zelia Pro Travel System is a fantastic choice, especially for first time parents looking for something more reasonably priced from a good reputable brand. I am grateful to have received this product through the Stellar Review Program.

[This review was collected as part of a promotion.] We received the Maxi Cosi Zelia Pro Travel System through the Stellar Product Testing Panel, and overall, it’s been a great addition to our daily routine! Right out of the box, we were pleasantly surprised by how easy it was to put together—always a win when you’re juggling a baby and limited time. The materials feel soft and high-quality, and we love that they’re eco-friendly. The bassinet is also on the larger side, which gives us confidence that our baby will be able to grow into it for a while. Even better, our baby seems genuinely comfortable and tends to fall asleep in it quickly, which makes walks that much more enjoyable. The under-stroller storage is another highlight—it’s roomy and easily fits all the essentials (and then some!). There are a few minor drawbacks to keep in mind. The car seat requires two adapter pieces to connect to the stroller, so transitioning from car to stroller isn’t quite as seamless as we expected. The strap release button on the car seat is also positioned a bit far back, making it a little awkward to press with one hand. We also found that the headrest cushion tends to slide down and can be a bit tricky to keep properly positioned. That said, these are relatively small inconveniences in the grand scheme of things. Overall, we’ll definitely be keeping this as our primary travel system for daily neighborhood walks. It strikes a great balance between quality and price, and feels like a dependable, thoughtfully designed option without being overly expensive.

[This review was collected as part of a promotion.] I have received this product as part of the Stellar Product Testing Panel. We love this travel system! It is exactly what we were looking for. I would have to say my favorite part is the soft fabric. I think we all want our babies to be comfortable yet safe in their car seats and this one fits that perfectly. The straps are easy to use and tighten/loosen. The stroller part folds up easy and is very light for what it can do. I LOVE the bassinet feature. I had been looking for a good one and this is perfect! We love to go on walks and it is perfect for naps or tummy time to look at all of nature. The basket on the bottom and easily fits all of the things that come with taking baby out of the house. I can fit my giant diaper bag along with toys, everything for feeding, outdoor blanket, and stuff for mom and dad with room to spare. I don’t have anything bad to say. I would recommend this product to any new parent and will gladly use this for next children!

[This review was collected as part of a promotion.] I received the Maxi Cosi Zelia Pro Travel System as part of the Stellar Product Testing Panel. It has left a very positive impression on me, especially during a trip to Hawaii where its convenience was truly appreciated. The travel system’s cozy fabrics and lightweight design are commendable, although the car seat felt a bit snug for my little one. To address this, I removed the bottom insert, which provided a better fit. The quality of both the fabrics and the seats is premium, adding to the overall comfort and appeal. The stroller’s durability is impressive, providing a smooth ride even on the bumpy terrain encountered during some off-road adventures in Hawaii. It held up exceptionally well throughout these challenging conditions. One of the standout features of this travel system is its versatility, offering five different modes. We have utilized all of them, and the transition from bassinet to seat is seamless, which is particularly useful with our 5-month-old. This flexibility is a significant advantage for parents who need to adapt to different situations quickly. The quality of the travel system is very nice, and it is easy to assemble. Additionally, the wheels can be easily removed to fit into a travel stroller bag, making it highly portable. However, there are a few areas for improvement. The shoulder straps could be more user-friendly if they were easily removable or available in a thinner option. The car seat handle offers only two positions, up or down and could benefit from more adjustable options. Lastly, the button to loosen the straps in the car seat is positioned a bit too far back, making it less accessible. Moving it slightly towards the front would make it easier to adjust the seat straps. Overall, the Maxi Cosi Zelia Pro Travel System is a well-designed product with a few minor areas that could be enhanced for even greater user satisfaction.

[This review was collected as part of a promotion.] I received this travel system from the Stellar Product Testing Panel. Overall, I had a really positive impression of the Maxi-Cosi Zelia Pro. It’s a very convenient, all-in-one system that makes everyday outings much easier. Being able to move the car seat straight onto the stroller without disturbing my baby is a huge plus. The fabrics feel soft and cozy, and my little one seems very comfortable in both the stroller and car seat. I also love that the car seat is lightweight, which makes it easier to carry. The 5 modes are very practical. Right now, my son still uses the car seat, so that’s what I use the most—but I can already tell the world-facing position will soon be my best friend. What I like most is how versatile and user-friendly it is—it really grows with your child and simplifies daily life.

[This review was collected as part of a promotion.] I’ll start out by saying that we are relatively new parents to a now 7 month old daughter. We received this travel system to test through the Stellar Product Testing Panel when she was just 6 months old, so we’ve had a chance to really put this to the test in our normal routine over the course of the last month. Typically that routine includes carting back and forth from daycare, but even more so - walking around our hilly town which is primarily residential mixed with a solid main street vibe. First Impressions * Visual Aesthetic - One of the first things we noticed is that right out of the box, the stroller looked very sleek. I was immediately attracted to the Black and Stone aesthetic and in particular, the design of the wheels is very appealing. Visually the system looks very luxe and well made. * Quality Touch Feel - The material of the bassinet that converts to the upright stroller is very soft to the touch and has an almost ‘scuba’ like feel. The sunshade is thick and protective from UV rays, but flexible and easy to extend or tuck away. * High-Volume Storage - The storage space at the bottom of the stroller is spacious and gives you plenty of room for a typical diaper bag x 3. It also has a higher frame to protect what you are towing from falling out. * Quick Start - From my husband’s point of view, it was extremely easy to assemble. (I am certain it would have been easy for me as well, had he let me play a part!) Out of the box and locked on the wheels and we were pretty much ready to go for a test-drive. Similarly, the base for the carseat was easy to install. Ultimately - a very intuitive system. What We Love * Comfort for Baby - By far and away, my daughter’s comfort in the stroller is my favorite part. Another stroller we had been using that was also a convertible travel system had been failing miserably in this area. The Maxi Cosi offers a wide center strap that allowed my daughter to have proper cushion and helped stabilize & center her which is mission critical, especially as she is more reliant on the support at this stage in her development. * Quality of the Materials - As mentioned above, the fabric — particularly on the stroller - was very high quality. The handle is a pebbled stone color and provides good contrast to the black frame and solid grip. The shine and design of the wheels are also a level above what I’ve seen available, offering both a playful & luxe element. All the materials seem durable and likely to withstand heavy usage. * Buttery Smooth Ride - Right out the door we recognized how smooth the handling of the stroller was — offering smooth sailing and what we called a “boat-like” ride. The stroller offers meaningfully\ better shock-absorption than others we’ve used to date. * Unexpected Features: Sometimes there are things that delight you, when you didn’t even know you needed them. There were THREE key features that stood out in this arena. --- The two-way swing bar - The ability to open the stroller bar from either side is awesome. Is it needed? No. Is it convenient? 100%. Also, the quality of the button to release each side should be noted - it’s up there! --- The cup holder - Again, never thought I’d care - but this cup holder can actually support my 40 oz Stanley Tumbler whereas past strollers would rotate under its weight, leaving me dehydrated on my walks. With this cup holder – I’m cruising, sipping and happy. --- Self-Standing w/Handle - When the stroller folds up, it doesn’t topple over and can stand on its own. That’s something we always have cared about. However, this stroller levels that feature up by also providing a handle that allows for easier manipulation and movement of the frame for loading into the car or elsewhere. What Could be Improved * Wide-Load: While this is considered a travel stroller, compared with other systems - we found this to be a wider ride and have concerns about navigating certain restaurants and locales without issue. To be fair, we straight up avoided those places when testing this stroller because of our concerns about width – and in actuality - it’s only 1” wider, but its enough that we noticed (24.5” wide if you’re wondering vs. 23.5” wide on our previous ride) * Fabric on the Car seat - This is one area where we weren’t as impressed. Generally, the car seat didn’t feel as high quality when it came to the fabric and seemed a bit like an afterthought in terms of the design and aesthetic. The cushioning less dense and a bit hollow. We wouldn’t say it was bad quality, but compared to the bassinet/upright stroller attachment, it left much to be desired. All in all, we absolutely love this product and would recommend it. It has become our new go-to for our day-to-day errands about town and we are super happy that our baby seems secure and comfortable, all while riding in style.

[This review was collected as part of a promotion.] The Maxi Cosi Zelia Pro Travel System is an absolutely beautiful travel system. It has a sleek design, feels durable, and the fabrics are incredibly soft and cozy. My baby seemed so comfortable in both the stroller and car seat. The padding is super plush and even the neck strap covers in the car seat feel soft and well made. Where this system really shines for me is the stroller. I love just how versatile it is for every day use. The 5 different modes make it easy to adjust depending on what we’re doing at any given time. If baby needs a nap, pram mode is great. Baby can lay flat and relax while we’re still out and about. Later, I can easily switch things around and set her upright so she can look around and enjoy whatever we're doing with her siblings. The Maxi Cosi Zelia Pro Travel System truly feels flexible and practical without being too bulky. The car seat, however, is more of a mixed experience for us though. While the car seat clicks into the base incredibly easily, I did find it larger and bulkier than expected. The base feels too big for my (2025) SUV captain’s chair, and the infant carrier itself is heavy and awkward to carry. I’ve seen the popular trick of wrapping your hand around the carrier handle attachment point, but that trick does not work here due to the design of the handle base and placement of the handle adjustment buttons. For both my husband and I, we found that the easiest carry option is to use the crook of your arm, which can become uncomfortable pretty quickly. Overall, I think this system is worth considering if a great stroller is high on your priority list. The stroller has been the standout feature for our family, and is now a permanent fixture in our SUV. If you want versatility, comfort, and a stylish look, the Maxi Cosi Zelia Pro Travel System has a lot to offer. I was given this travel system to try as part of the Stellar Product Testing Panel.

[This review was collected as part of a promotion.] I wanted to love this carseat. I really like the look and feel, and LOVE how compact the stroller folds up (see photo). I also love that the seat itself can turn into a bassinet/fold flat and you don't need a separate piece for a newborn. The canopy is a good size for the carseat itself, which is great, but the canopy is too short in my opinion in the stroller seat. Unfortunately, I didn't find the ride to be as smooth or easy to maneuver as it should be. We have a very packed garage and even moving the stroller in/out and around my husband's tools, other kiddos' bikes, etc. was difficult and the wheels frequently get stuck and don't turn well together to maneuver around obstacles. I found the wheel lock to also be "sticky." Overall, it might work great for someone who is looking for a carseat & stroller system that maximizes space efficiency and convenience, but doesn't need a lot of maneuverability; otherwise, I probably would not recommend. I was given this travel system to try as part of the Stellar Product Testing Panel.

[This review was collected as part of a promotion.] Thanks to the Stellar Product Testing Panel for providing me with this travel system. This travel system is very sleek and classy. I love the leather handlebars and touches. The black is very sleek as well. The main thing that stuck out to me is that the stroller seat converts to a bassinet, I love that it is one item. I have seen other strollers that have multiple attachments and I much prefer this style. With multiple kids of various ages this allows me to use the seat for different kids very easily. The basket is huge and I could fit about 3 diaper bags in it easily! Again, with multiple kids this is awesome because we constantly have so many things with us. The wheels on the stroller are smooth and large and I am excited to try it out in different terrain like cobblestones. I imagine it will do wonderfully. I am pregnant and can’t wait to use this with a newborn. The car seat is so lightweight. My only complaint is that the release button to loosen the straps is deeper back and hard to press. Overall this might be my favorite stroller and I can’t wait to use it more.

[This review was collected as part of a promotion.] Firstly, my baby loved this stroller & car seat. Usually my baby fusses when he knows he's going in the car seat, but once I got him buckled in, he was content and very relaxed...I think it tells a lot about the comfort and coziness of the car seat & stroller seat. When we received this travel system from the Stellar Product Testing Panel, it was incredibly easy to set-up. My goal is to always see if set-up is self-explanatory, and truly we didn't open the instruction manual until we needed to see how to change the modes of the stroller; it was that easy! I can't say enough great things about how smooth this stroller is to navigate, push, steer, glide, fold, and lift. I was using a combination of 2 other strollers for walks and travel and now I only want to use our Maxi Cosi Travel System. We walk nightly and baby enjoys lounging either awake or for a nap in the reclined stroller seat mode. We've been using the canopy with the zip mesh extension for more coverage and better air-flow. He enjoys holding onto the front swinging bar, which can come completely off if you want. It's soft and looks very stylish with the black fabric and pop of light brown on the stroller handle, stroller seat bar, and the car seat carrying handle. I'll definitely encourage my friends to put this on their registry! My husband set-up the car seat in the car and he reported it installed easily into our mid-sized SUV. He rides right behind me and the car seat fit well with extra space between the 2 seats. Overall, this system deserves a 5 star rating! I'm so thankful we got the chance to bring this daily necessity into our baby's world!

[This review was collected as part of a promotion.] I have been using the Maxi Cosi Travel System with an almost 9 month old. One of my favorite features is the extending hand bar when using the stroller. I am on the taller side & this is such a great feature that is surprisingly difficult to find. The leather features on the handle are also very comfortable. The stroller is smooth & I like how big the basket in the bottom is. It is easy to switch between bassinet and toddler seat mode + switching the car seat into the travel stroller vs the toddler seat. It does require another piece for each side - these do come with the stroller and you would have switch the toddler seat to the car seat if going back and forth but the additional adapters are worth noting. I really like the cup holder on this stroller. It’s larger and secure which is a big plus when putting the stroller in and out of your car - that’s not what you want to be looking for while your baby is crying. The stroller is easy to breakdown and folds up nicely. It is easy to complete and lift solo which is nice for a mom on the go! I like the sunshade and the breathability with the mesh. It’s nice to be able to unzipper if needed and it extends low enough for my little one to be covered. I did have an issue installing the base in my car. I ended up watching a video and that helped but I couldn’t get it tight enough at first to feel secure. This was user error but wasn’t as intuitive as I would expect which is why I rated this 4 stars instead of 5. I like the car seat a lot & that it comes with the infant insert. I received this when my baby was 8.5 months so we didn’t have to use the insert but it’s nice to have. He has lots of room to continue using this car seat and it’s lite enough I can comfortably carry him in it. The design is sleek and comfortable for both him & I. I received this product as past of the Stellar Product Testing Panel.
