Temperature balancing innovation

Sleep Number ® i8 bed is rated 4.0 out of 5 by 234.
Rated 5 out of 5 by from Worth every penny! My husband and I purchased the i8 after completing the sleep number test at our local store. Since delivery, we have fallen asleep faster and slept more soundly than ever. My back problem has disappeared (except for business trips). This bed is worth every penny. We only wish we would have made the change years ago.

Rated 5 out of 5 by from Great Sleeping We have had this bed for over a month now and are so happy we invested in it. We bought the king size bed because that is what we were used to. We are using very different numbers from each other and are getting some of the best night's sleep we have had in a long time. The only complaint (which is very minor) is that I don't like the squishy sound that it makes when I first get into bed. All things considered we love our bed!

Rated 5 out of 5 by from Great Night Sleep! Bought this a little over a month ago to replace a sleep number that we had for 10 years. We have always loved our sleep number but the new features, etc have made us even happier. My wife is an insomniac and with this new mattress even she sleeps through the night!

Rated 5 out of 5 by from I love my sleep number!!!! Bought this mattress about 6 months ago. I have never had a better nights sleep. As a chronic back pain sufferer who was visiting my physical therapist once a week, I cannot say enough how thankful I am for this bed! I have been able to discontinue my therapy and am sleeping through the night! My husband likes a more firm mattress, where as I little a little more give. I would highly recommend their pillows as well! Proper alignment=amazing sleep! Thank you, thank you, thank you!

Rated 5 out of 5 by from Best money spent ever! After years of going from the bed to the couch and back again because my back hurt and I was unable to sleep, this mattress has given me back my sleep, without interruption and no back ache anymore! Best money I have spent in a long time! Thank you, Richelle
