The cushion provides contoured support to your back. The gentle curve lays flush with the natural curvature of the spine, supporting the entire length of your back to ensure help you have better posture.
The air bladder is located on the cushion where it would come in contact with the lumbar region. You can deflate or inflate the air bladder to customize it to your body so it supports your lumbar region, decreasing uneven pressure from your vertebrae.
You can make any seat or chair comfortable with this cushion. Just slide the elastic strap over the back of the chair or car seat to secure it.
Features a side pocket that tucks away the hand pump.
