I hate to say this but the mattress didn't live up to our expectations. It's firm as expected but...it's just not what I hoped and dreamed a tempurpedic mattress would be. We tried it out, loved it at the store, but now that we've got to use it...not worth bragging about...unfortunately
The twin XL is idea for couples to pick the right kind of's comfort yeah it's 8 kind of comfort you each may need. My wife need ed the medium and I need ed the soft. We are both happy campers and the thickness of 12" is truly to their words as I took a tape measure to it all around. This is our 3rd temperpedic and it's has been worth it!
