Query: Stiff and uncomfortable

Not only is the foam extremely stiff, but the product is narrow enough that you have trouble getting comfy with what to do with your arms. I am going to try using the knee part for my upper body so the incline isn't so steep and using the foot piece to go under my knees. Very disappointed in this product, may send back if tonight isn't any better than the last 2 nights.
