I cannot find anything on Wayfair website on weight of this mattress. It's 90 pounds. I tried to put the mattress protector cover but it's too heavy to maneuver. I order a medium softness and that's what is on the box it came in but it's like a concrete slab and my shoulders are sore because of the mattress. I will get air mattress to put on top of this one so I won't have shoulder problems.
