  • 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

  • Flimsy padding!
Color: Leo Size: 1 Pack
Definitely narrow, which is great for 3 across seating. Padding on seat is very flimsy. Hey Cosco: Wouldn’t cost more than maybe a nickel for better padding!
