Only available from Hammacher Schlemmer, this is the set of gel-filled cushions that attach to a vehicle seat to support the head, neck, and shoulders and encourage proper posture while commuting. Secured with hook-and-loop fasteners, the top cushion keeps the head and neck aligned to prevent pain caused by slumping or jerking. The second cushion provides 1/4" padding behind the upper back, with raised sections that target pressure points on either side of the spine to help release shoulder tension caused by traffic or work stress. With a pliable gel filling that disperses body weight and provides support that is firm yet soft. Overall: 28 1/4" L x 16" W x 2 1/3" D. (1 1/2 lbs.)
