This is my 3rd Tempur-Pedic mattress, as the others tended to be transported into guest rooms for their enjoyment! I have had multiple knee surgeries, sinus, Achilles' tendon issues. I hike over 100 miles per month. I started out with the original mattress about 2006, then switched to a softer one 5 years later after surgery. I moved recently and sold the mattresses, and everyone wants to buy even a used Tempur-Pedic mattress. I bought the Pro-Adapt because of my activity and age (66). Love it. Never disappointed in their mattresses. I advise to go into a store, take an hour and try out the varieties. You won't be disappointed. Invest in yourself and your body.
From night one very comfortable as I did not like the hybrid. But the soft was what I expected in comfort.
We went into our Sleep Outfitters expecting go buy a more standard mattress. After trying several products we were encouraged to try the Temperdic. I have had recent back problems so was not afraid to spend the money on the Pro-adapt. I knew I could return it and choose something else if not pleased. As they say, after 3 weeks use, you will have to "pry this wonderful product out of my cold dead hands." It is just that comfortable. The sales staff at our store was very helpful and not at all pushy.
Upgraded from a ten year old queen cloud model, to king for me and the wife. Best sleep for both of us. Best money spent where I spent a third of my life!
