what is lumbar pillow
A lumbar cushion is a specially designed support pillow used for providing added support to the lower back, thus relieving or reducing lower back pain aggravated by prolonged periods of sitting. Typically, a lumbar cushion is contoured to conform to the natural curve of the lower back when seated. People who have lower back pain or muscle tension may benefit from using a support pillow at their office desk, in the car, or at home.
