This booster seat is slimmer so kiddo has more room to click the buckle...less frustration! We do miss the cupholders though.

  • Worked perfectly for my usage.
Color: Grape
For the price you cant ask for much more. Needed something that could easily fit in a suitcase for flights and for use in Ubers on vacation with our 4 year old. Worked great the entire trip, super light so it didnt take up alot of weight, small so it didnt take up alot of room and it was easy/quick to get in an uber which made the drivers happy. Overall a great seat. Wouldnt use it as an everyday seat but works great in a pinch or if you dont wanna lug a car seat on vacation. ... show more

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
