Oh my gosh!
Shorty, TN
I didn't think Temperpedic would make a difference in my sleep! I was so wrong. Being able to raise my legs just a little helps my lower back and sleep sound.

Box spring makes all the difference
Cammy, GA
I had an old tempurpedic mattress and a new platform bed. It needed a box spring, so I went back Tempurpedic. They had three heights to choose from, so I was able to pick the best one for our new bed. I got the middle height, and it's perfect. My husband and I are sleeping better than ever!

Right size
Smlogan70, OK
Bought this low profile foundation along with mattress. Our new bed frame was designed for mattress only but this foundation worked great to provide support but not raise mattress up too high.

We bought this bed and foundation this spring, and we love it! The foundation is nice and firm for our mattress. Thank you!

The Best
Carol B, VA
I purchased the cloud foundation and adjustable base about four months ago and now I get the best sleep ever. Before making this purchase, I never slept through the night; awake every two hours. I was also stiff and achey every morning. Now I sleep through the night and aches and pains are gone. I will never sleep on anything other than a Tempurpedic.
