Sore back....aches and pains....buy this one...extremely comfortable and you get big bang for your $$$$. Took a week to get used to it but I have settled in now. Only one small complaint......had to be degassed.....it stunk when I unwrapped it. Service department was fast and helpful with suggestions on how to degass the mattress. Having said that degassing mattreses in a box is endemic to all such matresses despite the brand so I found out after i purchased mine and did research on the topic. Highly recommended by Choice and that was the reason I made the purchase.
