Great slim booster seat ! Easy to install, I like that it folds up compact when not in use. I really like that it has the anchor clips still as not all boosters do

Perfect for a small car
[This review was collected as part of a promotion.] This booster seat is perfect for a small car. It's slim but has all the features you need. From the seat bucket accessibility to the sun visors, it has it all. I definitely recommend it. My 3-year-old was very comfortable on it with room to spare. It will last us a while.

Quality booster
[This review was collected as part of a promotion.] Great booster with removal high back. The back has built in visor sides to keep the sun off little ones face. Material is modern and soft enough to be comfortable.

Must have!
[This review was collected as part of a promotion.] This booster seat is awesome!! We put it in the back seat of our 2 door car and the slim design fits perfectly. There isn’t much too it which is great for cleaning and moving it in and out of cars. The cup holders are a great addition for our toddler and he is very happy in it.

Safety first
[This review was collected as part of a promotion.] I have to first start by mentioning my favorite thing about this booster seat, the seat clips/anchors! There are so many boosters that dont have these, it holds the booster seat in place so you dont have to worry about it slipping around, much safer with these anchors. There is also a designated spot kn each side of where to feed the seatbelt through. Collapses down to a decent size for storage or transport which is great when traveling. There are adjustable arm rest, 2 cup holders and a sunshade guard thing. Im not sure how effective it will be since its plastic but my car has sunshade built in my car anyway. This is a booster seat I recommend because they can grow with it. The high back extends to taller height and can be removed to just the seat part when they are big enough. Material feels breathable but comfortable and seems easy to wash. The only downfall is the collapsing part has 2 buttons on each side and then you have to have an extra hand or get creative to fold it in half.

Slim booster seat with lots of features
[This review was collected as part of a promotion.] My almost 6 year old was so happy to get an upgraded “big kid seat” and is so excited to go on car rides now. Installation was a breeze and the size is so much slimmer and lighter than her old 3-in-one seat making it easy to move between vehicles as needed . I love that it’ll grow with us and become a backless booster when we are ready for that. I’m a big fan of the spot in the back that holds the manual and I also love the sun visors to help protect her eyes from the harsh summer sun. The cup holders are a good size and convenient for her to reach. Overall I am so happy with this booster seat and think it’ll be a great fit for our family.

Comfort and ease of installation
[This review was collected as part of a promotion.] We have been using this car seat for our 6 year old for couple months now and can confidently say it’s slim and very comfortable for him. It feels very secure once anchored on and with the car seatbelt. Also, was super easy to install and it’s very lightweight so we move from car to car. Love it and will buy a second one for my husbands car. Also, love how the car seatbelt fits a bit lower to fit his size comfortably. Lastly didn’t realize you can detach the back portion and use as a booster so loving that too! Thank you!!

Great
[This review was collected as part of a promotion.] So nice to have some shade while still using a booster seat. Sometimes things like that get lost when they get older. Keeping my kiddo safer for as long as possible is so important! It’s lightweight so easy to get in and out!

Amazing fast to install car seat
[This review was collected as part of a promotion.] I know I'm not the first nor the last to say, I hate not taking my car places and having my kids ride in a different car because of their car seats but the KOA Slim Plus Booster Car Seat with Side Sun Visors in cosmic black made things so much easier. My brother frequently visits and he always wants to take his car. Its convenient because it's bigger and i don't have to waste the gas. Well the KOA Slim made things so much easier. It was folded so at first it was a little tricky to get it loose but after I got rolling, it was such an easy installation. And my son loved putting the flip up arm rests up and down on his own. I normally dislike putting car seats in the middle of the car because of how bulky they are but this one was so SLIM! just like the name implies. I love the built in side sun shields, if the sun reaches him, it keeps his little face shaded. When the instructions say the latch stays put, it really does stay put and the seat clips in so it doesn't slide around when empty! THE SCALLOPED BASE is amazing! I cannot tell you how much trouble I always have with putting the seat belt on and in this case, it was so easy! The back rest folds easily so when you're not using it, it's easy to tuck away to save space when not in use. My son is growing at such a fast rate, so the adjustable headrest is music to my ears. He falls asleep and I love that it will grow with him. Overall, the KOA Slim Plus Booster Car Seat is a great car seat for trips and every day life! It is 2 year old approved!

Good choice for kids
[This review was collected as part of a promotion.] This car seat is stable and really comfortable, my son sit on it on a 2 hours road trip and didn’t have any issues or discomfort. Adjust the buckle easily and the side sunshade works awesome. The build and design look really neat, safe and stable.

Great slim quality booster
[This review was collected as part of a promotion.] Great booster seat. Slim and compact design. Good quality. Easy install. Great features. Love that it folds for easy portability and storage. Like that it has the side sun visors. Comfortable and supportive. Good padding. My toddler is unfortunately still a bit too small for it so I couldn't have her use it yet but looking forward to her growing into it as it's much more convenient to use than her current car seats she uses. Overall recommend and can't wait to get some use out of it. Was super excited to be able to try it!

Light weight, grow with your child booster!
[This review was collected as part of a promotion.] We have 2 kids in boosters currently so finding a well made functional one is key. This Baby Trend booster is very versatile. It can grow with your child, extending with their height, as well as the ability to remove the back completely. My daughter fit secure and the adjustable sun visors were a nice added feature. She can buckle herself which is a must for me. The fabric seems very easy to clean and wipe off. It’s light weight and can fold in half for traveling or transporting to different cars. Highly recommend!

Slim booster seat
[This review was collected as part of a promotion.] I Received the Koa slim booster ca seat by Baby Trend to review. This booster is perfect for our growing family. Love that it folds up to store away when not in use. The side sun visors are a great addition to keep the sun out of little one’s eyes. Would recommend checking out for your littles.

Decent booster seat.
[This review was collected as part of a promotion.] The booster seat was easy to install and the instructions were clear. My almost 5 year old fits it well and it will continue to work with her as she ages. The design seems to be safe and durable enough. It is easy to switch from the main car to the other car. I love the added features of the sun visor, arm rests and my daughter loves the cup holders.
