This mattress never fully decompressed. Once it arrived, I took it out of the box, unrolled it, and let it sit two days. It has now been over a week and the bed is still compressed. the middle section of the mattress seems to be ok but both ends are still flat. I am having to use an old comforter under the top of the mattress just to make sure the pillows are even with the middle of the bed!!! I am very disappointed with this mattress and I cant return it now that its out od the box.
