What a difference!
We love this topper! We wanted to try the topper before committing to the whole mattress. We have a bed with a memory foam pillow top and both of us were waking up all during the night with sore hips and shoulders, constantly having to readjust. We actually put this topper over an older mattress because it would have been too high on top of the current mattress and even on top of an old, kind of crappy mattress it's 10 times more comfortable - no more pain! We still plan to go in for a whole king size mattress eventually but this will definitely hold us for awhile.
