I’ve had this for 5 months now. When I first got it, my back, especially my hips felt so much better. But now after only 5 months my hips are hurting when I’m laying on my side. I purchased the plush, now I wish I would of purchased the medium. It is sinking in to much when I lay on my side. I’m just past my 120 day return policy so I’m stuck with it. So if you are thinking of getting the plush just remember it will get softer after just a few months use. I paid to much to just get a new mattress. But I would recommend diamond mattress to anyone. I bought a king size mattress.
