c4

Plush softness with adjustable comfort

Sleep Number ® c4 bed is rated 3.9 out of 5 by 177.
Rated 5 out of 5 by from Never slept better! I know people who own Sleep Number beds and they just rave about them. I didn't get it until I walked into a store last November and actually laid down one. I played with the remote and found my perfect setting. I am a 70. After years of back injuries and surgery I can finally sleep through the whole night!! I've never looked back.
