Some of the best sleep I have had comes from using this mattress. I was a little apprehensive of the mattress at first since it is not as thick as standard springs. But over time I disregarded this worry because I am able to sleep more soundly than ever before. I find that I can fall asleep comfortably at any position and not worry if the bed will contour to my body in a comfy and supportive manner. I even enjoyed the unboxing process and watching the mattress expand almost instantaneously after removing the plastic.
This is the most comfortable mattress I have every used. It has so far stood the test of time and is still keeping it's shape. I just bought one for my son's room as well.
