I bought a very high priced Temperpedic Memory foam mattress, I paid a total of 3600.00 for it and the frame, why? Because my back was in bad shape and I thought it might be helpful. NOT. I have yet to even use the fancy part that lifts my head or feet in the air, nor the vibration, nor the heat. I think I must have experienced a sucker day. And worse than this is the fact that the furniture company that I bought it from cheated me on the amt due, I am still trying to find a way to deal with them, may end up taking them to small claims court. I do not like the fact that when I set on the mattress it sinks way in, it does come back but I am not sure how long this will last, and the other part right beside me, is like a stiff mountain, my partner is dead so I live alone, and am the only one in the bed, the other side never gets used, and i keep trying to break in more of the mattress but it is hard to move on it, everything considered if i had it to do over again, I would try to find another regular mattress like I had before, it was very comfortable, and I only paid about 500.00 for it, about 25 years ago, it lasted that long and was far from being over. Live and learn, I guess. I really like an air mattress better than the one i got.
