Great inexpensive booster for travel
We bought this for our oldest son's vacation and honestly didn't know what to expect. We had it shipped directly to where we were staying, so we never even got to see it before we actually needed to use it. Thankfully, it worked out perfectly. Our son is a large five-year-old, and he fit comfortably in it without feeling cramped. It's lightweight, simple to use, and easy enough for him to get in and out of on his own. The booster also feels sturdier and better-made than I expected for the price. It doesn't have much extra bulk, which made it especially convenient for travel, and moving it between vehicles was easy. For such an inexpensive booster, we were very happy with it. It did exactly what we needed it to do, our son was comfortable, and I'd absolutely buy it again for travel or as a spare seat.

A Great Transition to a Big-Kid Seat
⭐⭐⭐⭐⭐ My grandson absolutely loves his new big-boy seat! One of the first things I noticed was how lightweight it is, which makes it easy to move between vehicles when needed. It also stores very easily in tight spaces when not in use, which is a huge plus. The design is simple but effective. The seatbelt fits securely underneath the armrests, helping keep the booster seat in place and providing added security for my grandson while riding. He finds it comfortable, and I appreciate the peace of mind knowing he’s riding safely. Overall, this is a great booster seat that is practical, easy to use, and comfortable for kids. I would definitely recommend it to other parents and grandparents looking for a reliable option.

Will buy this again when my next kiddo needs a booster
Easy to use, lightweight. Seems to be durable, I love that it can fit in small spaces, feels safe as it checks off all our boxes. Just wish it had cup holders haha then it would be a 5 star!!

Super Lightweight!
Perfect for what it’s meant for. Kids are comfortable and I like how I’m able to move it around easily because it’s so lightweight. No cup holders but still able to fit easily.

Cosco booster seat
It’s perfect and works exactly as intended. The booster seat has a label on it explaining in how the seatbelt goes. Lightweight and compact. Fits in all my vehicles. Switching between cars is super fast now and the padding is adequate for a child.

Does the job
My kid complained about a sore bum after 2hrs drive. So.. in the end it's not too comfortable..but then again.. how often do you ride 2hrs if you don't have your own car. Right? Sturdy and looks good.

Buen producto
Me imaginé que era un poco más acolchonada, es algo delgada la cubierta. Llevamos dos semanas utilizandolo y hasta el momento no ha habido quejas de mi niña de que sea incomodo o algo así, comento esto ya que es de plastico duro. El asientito va prácticamente suelto, solo se gancha con el cinturon de seguridad, no se ha resbalado ya que le puse un protector al asiento.
