  • Perfect Booster Seat for Everyday and Long Trips
Color: Organic Waves Size: 1 Pack
We are really happy with this backless booster seat. From the start, it felt sturdy and well-made, which gave us peace of mind. Our child finds it very comfortable, even on longer car rides, and the design makes it so easy for them to buckle themselves in without help. That’s been a huge convenience for us as parents. We recently took it on a long road trip, and it proved itself even more. After hours in the car, our child stayed comfortable, and when we had a few spills and crumbs (as always happens with kids), it was surprisingly easy to clean. Everything wiped right off, and the seat looked good as new. The booster is lightweight enough to move between cars quickly but still feels solid once it’s in place. Overall, it’s safe, reliable, and parent-friendly, and our child genuinely likes it. I’d recommend it to anyone looking for a no-fuss, dependable booster seat for everyday use and longer trips alike. ... show more

  • Convenient but feels bit uncomfortable
The Cosco Topside Booster Car Seat is incredibly convenient due to its lightweight design and ease of movement. It's perfect for families on the go, as it's easy to transfer between vehicles or store when not in use. However, I deducted one star because it lacks adequate cushioning, which affects its overall comfort. Sitting on it feels akin to sitting on a hard plastic seat, which may not be comfortable for longer car rides or for children who are more sensitive to seating comfort. Despite this, the booster seat meets safety standards and provides a secure option for children who have outgrown their car seats but still need a boost for proper seat belt positioning. Its simplicity and affordability make it a practical choice for families needing an additional booster seat for occasional use or for short trips around town. ... show more

My kids like them, we bought two one for each car, easy to clean, good quality, cup holder is easy to pull out and big enough to hold their water bottle, nice color, and easy to remove cover to clean. When apply seatbelt, the seat is holding in tight and safe. Simple to use. Very sturdy material.

  • Fits between 2 car seats
Color: Leo Size: 1 Pack
Perfect for granddaughter that is 9. It raises her up so seat belt fits better and it fit between two car seats. It could use a little more padding to make it more comfortable, but for short trips it is fine and meets my needs.

  • Lightweight booster seat with easy maintenance
Color: Grape Size: 1 Pack
This seat is lightweight and easy to transfer from one vehicle to another. It does not have a cupholder, but it does have little side handles that can come in handy when used to push out of the chair or get settled in. The fun color also makes it a happier item to use for my little one versus the standard gray black colors. Easy to wash with a fully removable pad. Rated for safety Priced reasonably ... show more
