I am a large person. 6'-7" - 250 LBS. This bed has zero support and is very hot. The deeper my body sinks into the mattress, the hotter it gets. We have had our mattress for 1 year, and I was hoping that my experience would improve, but it has not. I still wake up every morning stiff and longing for some comfort. Not what we were expecting or wanted. We tried to get a refund but the allowed time has already passed.
