Well after 4 months of house renovation we finally got our Tempur-Choice Luxe with adjustable base. So far so good. Adjustable base is the bomb. Worth the money and a must have. The air mattress works great giving an adjustable feel from soft to medium-firm. Wife likes soft, i like soft /medium. Back and neck issues are going away. I don't feel the need to go sleep on the couch in the middle of the night. 10 out of 10 in my book.
BTW, no heat retention at all.
