Keep your child in a car seat longer with the Diono Solana Booster Seat - Graphite. Made for children 40 - 120 lbs., your child will be able to use this booster seat until he hits the recommended height of 57-in. Designed for comfort and safety, the booster seat features a reinforced seat bottom for lap belt safety, thick foam for cushioned support, an angled seat bottom to prevent submarining, and a longer seat bottom for leg support and comfort. The LATCH system allows you to secure the seat to the car so it doesn't move around when unoccupied.
