Sleep Number ® c4 bed is rated 3.7692 out of 5 by 65.
Rated 5 out of 5 by from Love it! I love the mattress! We bought this because we both had back problems and neither of us liked the same firmness of any regular mattress. She likes hers medium and mine soft. Before we bought a mattress we thought just the opposite so it's great that we can adjust it to fit our needs. Best decision I ever made to spend a.little more money and get a sleep number.

Rated 5 out of 5 by from Good waterbed replacement We had a waterbed for over 30 years and loved it, just finally decided to move on. This is a really good transition as we get a similar feel with even more ability to customize.

Rated 3 out of 5 by from adjustable comfort levels Bought over a month ago but was just able to get it set up and started using April 24, but I feel like I am sleeping deeper. Just changed setting to day for a little firmer to see if that changes ..only been using 1 week...

Rated 5 out of 5 by from Over 13 years and counting We have had the bed way too long but buying a new one is out of our budget. The foam sides are pretty much broken down and I've had to put a plywood base under the plastic base. It started breaking several years ago.

Rated 2 out of 5 by from Jury's still out... I received my C4 bed about 6 weeks ago, and we are still having difficulty adjusting to it. I am sleeping on 95, I've been used to a very firm mattress and I've tried everything from 85 -100. My partner prefers a softer mattress, but he's tried everything from 65-95 and has settled on 95 as well...neither of us is feeling so well rested in the morning. We seem to have no trouble falling asleep, but both regularly wake up in the morning with backaches. I did not purchase the Sleep IQ, it was out of my budget. I am seriously considering returning the mattress, I don't see why I should spend 1/4 of a year trying to' get used' to a new mattress. Either it's comfortable or it isn't, yes? The C4 seemed like a great idea, was affordable, and of course was comfortable in the showroom, but I can't say we are happy with this purchase. I will update review when I decide which direction to go....Quality of the product seems fine, ignore my value rating as I can't say yet!

Rated 5 out of 5 by from Best Bed Ever! Will never go back to a regular bed. Beyond relieving our back pain my husband and I both had, I couldn't believe the amount of energy I got back. I drive for work and am in and out of the car all day. I noticed by just the second week that my energy by the mid afternoon was just as good as when I woke up! Best decision we ever made to get not only a Sleep Number bed but the style we chose. So incredibly soft and comfortable, I can't wait to get more accessories and now ready to get a new pillow. Thank you Sleep Number for finally an incredible night sleep and being able to not dread going to bed at night!
