Title: Useless
Review: With no strap to keep it in place it would slide if it were firm enough to have any sort of support. It just squishes in any kind of uncomfortable shape, to which you have to sit up and readjust and play with it and even then it provides little to no lower back support. Save your money and get the Duro-Med Relax-a-Bac with Insert and Strap, it works so much better. And provides firm support while being comfortable and strapped down.
