This was soft and has 'a thousand' coils. It sinks, it's very hot, and it's too hard/quicksand feeling while being 'too soft' on top. So you feel the 'hotdog' sensation of an old mattress from day one. Never had back pain -EVER - before this mattress. It hit the pressure points in my back to the point where I literally jump out of the bed and would rather sleep in a papasan chair.Worst mattress I have ever owned!
