The adverstisements look great and the customers on tv and celebrities on the radio make you think this bed will solve your sleep problems. This is the worst bed I have ever used. It was also the most expensive. The bed is not infinitely adjustable. It adjust in increments of 5 so if you want a 52, you have to go with 50 or 55. Now that seems petty, but when 50 is too soft and 55 is too firm, what are your options? I wake up at least 3-4 times a night in this bed. I shift from side to side and cannot stay comfortable in one spot even when I am on my back. If I get 3 solid hours of sleep I consider it a win. The bed does not constantly adjust to your body. It adjusts when I get in it and that is it for the night. No matter how I toss and turn, it stays the same. The trench effect that you may read about on other sites is real. You can get lost in the middle of the mattress and have to climb out to one side or the other. We thought this would be a mattress that we would enjoy, but it is a very overpriced nightmare and a waste of money. When you see the advertisement for mattresses under $1000, do not believe it. After you buy the mattress, frame, and their mattress cover (they will not warranty your mattress without their overpriced cover), it is easy to be over $3000 for a bed. Open your wallet and watch the money fly out. For that same price, you could buy a really nice mattress that will not let you down.
