Medic-Air Back Cushion 18" x 15" Blue by Medic-Air

A few puffs of air is all it takes to start using this very portable back support. Adjust it to perfectly fit your back with a little extra air, or a little less air. The elastic straps allow you to fasten this support to the back of most chairs and then position it at a height that's comfortable for you. You're looking at a truly "pocket-portable" back support, with a patented design to support the curves of your low back. Take it with you for the home, office, or car. Manufactured from medical grade nylon-coated vinyl with open-valve system. 18" x 15".
