Booster Seat Cushion,13" x 14"
4-1/2" to 5" Rise When Inflated (w/Suction Cups)
REVIEW: This booster seat works well and is very comfortable, it works great for small children or shorter folks. Adding marbles is a great idea, thanks to whoever came up with that idea. I added some small packs of marbles and the seat stays in place. The suction cups also help to keep it in place.
