The Wal-Pil-O is truly four neck pillows in one because each pillow has two different borders (narrow and wide), and two types of center sections (soft and medium). The #1 prescribed pillow by Chiropractors, medical doctors and physical therapists since 1977. Also available in a Air Pump-Up model for customized comfort. The dimensions are the same for either this item or the ?pump up? version.
Dimensions: 24 x 15 x 4 (on each side)
