I sleep very well except I cannot turn over in bed due to the softness of the mattress. I don't know if this will get better within the 90 day period, I might have to exchange it for a different one. I sleep very sound.
I purchased two TWIN XL Medium Adapt mattresses from two different stores within two months of each other and within the last six months. The first mattress is much softer than the second one,, i.e. the firmness is lacking. It is obvious that the mattress is defective but Tempurpedic will not warranty it because their claim is that the mattress has to have a sag or depression. They believe that the same model does not necessarily have to feel the same from one mattress to another. I interpret that to be that they have quality defects in production and they don't want to stand behind their product. I submitted a warranty claim but Tempur wants to ignore it because it is not in their interest to stand behind their product. Tempur is asking for pictures that are impossible to provide.
I've had this mattress for less than a month, and my only regret is that I did not purchase it sooner! Great support and comfort for all sleeping positions. Premium product!
