With this back cushion it is nice that it stays in place, so it can continue providing ideal support. The lumbar cushion has two straps at the back, with which you can attach the product to the chair. Because the straps are adjustable, it fits different size chairs. The back cushion, can also be used to improve your sitting posture. There is an MDF plate in the cushion, so that it can offer more support.
