| Pillow Fits Your Back Like A Glove. The
only back support product endorsed by the American Physical Therapy
Association. The secret to this incredibly satisfying pillow is the continuously
readjusting cushion of soothing air that is compressed
by your own body weight and responds to your movements.
A handy strap holds it securely to your chair. Blue nylon
covered vinyl pillow is 18"W x 15"H and inflates to the recommended 1/2" thickness with just 2 to 3 puffs.
