Sturdy rail but assembly took longer than the bed

[This review was collected as part of a promotion.] We bought this for my 4 year old who transitioned to a big kid bed today, and it seems like it will do the job now that it’s set up. The rail itself is sturdy and gives me (and my anxious kid) some peace of mind. The mesh panel is nice but probably more important for younger kiddos. That said, assembly was more of a headache than I felt like it should have been. It honestly took longer to assemble the rail than it did to assemble the entire bed frame! It arrived in a small box and although assembly isn’t complicated, the instructions aren’t clear. We opted for screwing it into the slat boards because I honestly couldn’t figure out the strap. It’s secure but it means we’ll need the drill to take it down when the time comes. It was just a bit more chaotic and complicated than we really needed on a big day of moving a kid to a new bed.

This is perfect for our kids and lives in the RV

[This review was collected as part of a promotion.] There are so many reasons why this is absolutely perfect for an RV. It’s lightweight, removable and perfect to add some peace of mind for the kids when they are sleeping in the RV bed (which is just a dinette table that folds down into a bed) that is just a little bit higher up than the normal bed. The netting is perfect to let you see what’s going on or if you are using a baby monitor to keep an eye on the kids.In addition, the netting helps if you have younger babies and they roll up against it for safety. The package came well packed and assembles easily

Perfect bed rail for toddlers!

[This review was collected as part of a promotion.] This was the answer to our needs when it comes to our family camper for two toddlers. The bed is a little bit high in our camper, so this just gave us some added piece of protection to know that they’re not gonna roll off the bed in the middle of the night while they’re sleeping. This was a breeze to set up and we were able to bolt it to the bottom of the bed so we can slide it in and out as needed.

Can be portable or semi-permanent

[This review was collected as part of a promotion.] As a mom of three toddlers, having one of these on hand is a must. The first time using this, we took it on a trip with us to use on the hotel bed. Even though bed rails are typically available from hotels, we prefer to bring our own. Setup for this bed rail was super easy, and the end result was sturdy and convenient (with the fold-down feature). The box comes with parts to make this a semi-permanent solution as well. Great quality product that’s worth the price.

Amazing bumper for cosleeping

[This review was collected as part of a promotion.] This mattress bumper is a must for those who co sleep with their baby. We don’t typically cosleep but on vacation I love to bring this with us as it’s lightweight. I appreciate the size and it fits well in our king size bed. This is a must for every parent. Installation was quick and easy and only need minimal screwing.
