plain and simple this bed is perfect (for us) we got a king size mattress and we (two adults and 3 medium dogs) fit perfectly and slept wonderfully! i woke up the first morning feeling refreshed and not sore one bit! its the best $****ive ever spent! truly. we were comfy & warm (nights in wintery Maine get cold) but not too warm (which can happen with the tempur-pedics). best of all i didnt feel it when the dogs woke up and moved around... no more squeaky slanty beds for us!
