I voted Tempurpedic, but ours is that type, but not that brand. I probably should have chosen "other", oops. We love it. I can sleep anywhere, but my husband is very particular and he loves the memory foam mattress. My parents just got medical grade beds and mattresses and they are fantastic! I would totally sleep on them...they have vibration options, as well as being adjustable. I haven't slept on them but I lay down on them the last time I visited and would definitely recommend them.
