This pillow was purchased as a gift for my dad, who has Degenerative Disk/Spinal Stenosis, etc., because it appeared to be just what he's been looking for. He wanted the pillow to sort of "cocoon" him, giving him support all around his body, and because it looks exactly like that's what it would do, I couldn't wait to give it to him. Well for one thing, the fabric is hard, stiff, scratchy, and incredibly hot, making it nearly impossible to be comfortable in/on. More importantly, the pillow itself just didn't perform as it was touted to. It flattened out quickly in spots making it slightly lumpy, so the support just wasn't there. There were a few other minor issues of lesser concern, but those two things seem to be the most problematic. For anyone deciding to go ahead with this purchase, at the very least, I highly recommend making (or having made) a pillowcase with a high thread count cotton fabric, for comfort and perhaps to help with keeping it a little cooler. The existing cover can literally make you perspire profusely if it's right against your skin. Of course, this will be one enormous pillowcase, as the pillow is truly gigantic! Best of luck to all!
