Well it's 2 nights now....better than the older one I had. purchased in 2003....I was due for one, I put a featherbed on top of the memory foam mattress....going to give it some time for me to adjust. It sure was heavy, I had to lug it up 13 stairs, as soon as I started to take off the plastic it started to expand, expand and expand...to the proper measurements....For the price it's worth it, if you are looking for a hasten bed this ain't it....but it will do for me.
