Sleep Bummer
Too Hard
Best Uses
The company claims that they focus on customer satisfaction. However, when we tried to exchange our mattress for a softer mattress, they refused to accommodate our request, although we had only had the mattress for 2 weeks. Their advertisement for customer satisfaction guarantee is not true. I would never recommend this company. Instead of being called Sleep Number a more appropriate name would be Sleep Bummer.
How long have you owned it:
A month or less
Bottom Line
No, I would not recommend this to a friend.

Guest Bed
Primary Bed
I've had this bed for over 10 years and it is, beyond a doubt, the best bed I've ever slept on. Back pain gone. Much better night's sleep and it's adjustable. My husband has it like a rock. For me, sometimes I like it firm and other times, like when I'm sore from gardening or working out, a bit softer is better. The point is you can choose. And when my husband moves around or gets up I don't feel it. I just wish something would go wrong so I could get a new one.
How long have you owned it:
More than six months
Bottom Line
Yes, I would recommend this to a friend.

Design Change
Best Uses
Be advised that the model reviewed here was redesigned 4 or 5 months ago. We have had classic series twin beds for over three years and although we have a P5 queen decided to get a new classic for ourselves and use the P5 for guests. The enhanced classic is anything but enhanced. The padded topper is a much cheaper material and construction. Air chambers are now 3 1/2 inches instead of 5. There are no longer firm rails around the mattress edges so when you sit on the side it totally flattens and if you sleep close to the side you feel like you are going to roll off. This is our 5th sleep number. On all previous mattresses the foam pads fit precisely with trimmed corners. On this one the bottom and top pad are larger than the mattress cover size and therefore need to overlap or roll up the sides resulting in an odd shape final product. This one will probably be returned.
