I've been sleeping on this mattress for a couple months now and I must say that I am truly disappointed in this purchase. I awake every morning with an aching back more so than from the previous mattress that I tried to replace. This medium hybrid honestly feels more like the be of those cheap soft foam mattresses that sinks with the weight of your body when you lay down. I don't get the point of the springs because they offer no support beneath the soft layer of sinking foam. I felt compelled to warn any potential buyers, as I am pretty much stuck with the mattress for the time being, being that I purchase and shipped out of the US. On the plus side, it is a pretty good looking mattress that would work well for side sleepers and feels nice to the surface and touch.
