If there's one area where car seats don't provide adequate support, it's the neck. Sacro-Ease's Neck Ease addresses that, with a supple cushion that extends from the base of the head to mid-back. A combination of memory foam and poly give firm but supple support, and the Neck Ease also features a strap that allows for placement where it can do the most good. Removable, washable cushion. Perfect for getting the most out of soft, collapsed springs and upholstery on a high-mileage car!
