OUT OF STOCK- PRODUCT UNAVAILABLE Todays contoured vehicle seats often tilt infant carriers back towards the rear of the seat, positioning infants at an incorrect angle. Sit-Rite helps to level rear-facing child safety seats and position infants at the proper angle. Forget rolled-up towels. Sit-Rite will not flatten during tightening and installation, and the dense foam construction adds firm, lateral support to the vehicle seat to help discourage sideways tipping. Site-Rite fits all rear-facing safety seats and infant carrier bases and is LATCH compatible.
