I’ve had this now for 4 months and I can’t wait to get rid of it! I got this to try and give us another year with our mattress while in between moves. The first month it was great no complaints like sleeping on a cloud. But it quickly went from being great to really awful it’s no different than sleeping on a saggy mattress.  It gets worse and worse as each month passes losing its shape. We hate it and I wish we went with something less expensive. It just doesn’t keep its shape for long. Would probably work better with a firm mattress underneath. This would probably work best maybe in a guest room that isn’t used often.
