The Britax Parkway belt-positioning booster car seat has been designed for increased safety incorporating deep torso and adjustable height head support. True Side Impact Protection, developed by Britax engineers, has been confirmed through rigorous side impact sled testing to better contain a child in dangerous side-impact crashes. The seat shape correctly positions the lap belt over your childs pelvis while the shoulder belt guide keeps the vehicle belt comfortably away from his/her neck. Plush, washable fabrics, convenient drink and snack trays, reclining backrest, color coded vehicle belt guides, and the contoured, slip-resistant base of the Parkway Booster Car Seat provide safety, comfort and convenience in true Britax fashion.
