This is the lightweight back cushion that folds in half easily for travel or nights out. Weighing less than a pound and fitting easily into luggage, it provides firm, comfortable support, encouraging good posture by keeping the back straight when used on a plane or car, or simply at dinner, a movie, or performance. Equally suitable for office use, the cushion uses a proprietary closed-cell polyurethane foam made from varying cell sizes that allows the cushion to conform to your back. When turned over, two built-in vertical lumbar panels provide additional support by keeping the spine neutral without the slouching allowed by non-supportive pillows. Non-slip treads keep the cushion in place as you shift your weight. With a removable, washable zippered 100% polyester cover. Gray. 14" H x 10" W x 2" D. (1 1/2 lbs.)
