The TN mattress is comfortable but when your used to a pillow top mattress it’s very Hard to sleep on. I have to go buy a memory foam mattress topper to be able to sleep.
It's comfortable, but lately, it's feeling as though the side I sleep on is now lower that the other side, one of the reasons I bought a new mattress in the first place, but the old mattress didn't feel that way until after more than 10 years of use.
