Comfortable and lightweight, the Solana 2 pack makes the perfect travel companions for your on-the-go kids.

Dual integrated cup holders keep drinks and snacks close, while the easy-to-remove covers are machine washable for quick cleanup. The 8-year booster is all you'll ever need for your big kid from 40 to 120 lb. Two built-in elastic cup holders make it perfect for road trips, keeping drinks and snacks within reach.

The contoured premium soft fabrics, with layered foam padding, provide comfort and support, and can be easily removed for machine washing. The shoulder belt positioner helps to properly position the vehicle seat shoulder belt, and easy access to the seatbelt buckle assists your big kid with self-buckling. Remember to always double-check the seatbelt placement.

This lightweight booster is safely and securely installed using the vehicle seat belt, making it easier to remove for storage in the trunk when not in use.
