Just the right amount of firmness and support. Forms to every contour of your body quickly so it's very easy to drift off to sleep. No more tossing and turning and morning pain ans stiffness is greatly reduced.
Husband and I both have bad backs, but apparently have grown to thrive on our 11 year old Tempurpedic, which was firm initially, but with constant use by us and two large dogs had apparently became a bit less firm. Our mistake was not going to the store to try the mattresses. When my husband finally did go he received quality advice from the sales person, thus making the decision to exchange the firm ProAdapt twin mattress for a second Medium ProAdapt. Tempurpedic was more than sympathetic and helpful. Their 90 day exchange policy is more than fair. We needed to pay an additional shipping fee, but, after agonizing for days about this finally decided the medium was the way to go. We do appreciate Tempurpedic's flexibility. Thank you, all!
When the mattress first arrived, we thought it might be too firm. But from the first night's sleep, we realized that we had made an investment in the proper choice.
We love our King ProAdapt Firm. We had a Classic Deluxe and needed to replace. We knew the new mattress would feel extremely firm at first but softens up after sleeping on it. Worth not having backaches. The ProAdapt is taller than our older model so being 5'3", I have to have a step stool to get onto the bed. Minor problem for the comfort. We also have Tempur-Pedic mattresses in our guest rooms.
I've been sleeping on this mattress for nearly a month and I'm not sure it's the mattress for me. It's pretty squishy and doesn't seem to adapt as well as I thought it would as I change positions during the night. I intend to give it more time so I shall see.
