Probably the best bed in the world

Sleep Number ® x12 bed is rated 3.0 out of 5 by 25.
Rated 5 out of 5 by from we bought the flex mattress. we bought our flex mattress in the king size. I absolutely love this bed. when we leave home and travel for a week, I just cant wait to get back to my bed. for those of you that have complaints, please make sure it is set up from the company. they secure the mattress to the frame so it wont slide, like I have read complaints from some about the mattress sliding. and for those of you that have the other miner complaints, just call the store and they will be glad to address your problems. My delivery crew was very professional. I live in the Eugene, Oregon area.. these people are experts. you would think I work for the company, but I don't. I just love this bed so much. we paid $8000.00 for ours and possibly going to get the same one for a second home. I see the price went up since we bought ours. I also read a complaint that the bed is hard to make. If you have the flex top, just raise the head part to you can make it with ease. love- love- love my bed..

Rated 5 out of 5 by from Worth the money My wife and I decided that we would buy our "dream" bed (pun intended), and purchased the X12 last September. I must say that 6 months in, we are more than happy - I love all of the features, and use them. Simply said, there are times when it is nice to have a mattress you can sink into, and times when you want it to be more rigid. I feel that our sleep has improved dramatically, and it was a great purchase.

Rated 5 out of 5 by from Best Bed Ever! I reluctantly agreed with my husband on the purchase of this bed the price was overwhelming. We both have sleep disorders and figured it would be worth a shot. We got the bed and there was a defect with the base. Sleep Number support immediately ordered us a new base and it has already been delivered and is running fine. I can't believe how different a decent night sleep makes you feel. Seriously we love this bed.

Rated 5 out of 5 by from "Best bed in the world" is an understatement! We bought a Split King X12 bed and we couldn't be happier. I used to constantly have back pain sleeping on all sorts of beds/mattresses. On this bed, my back pain has gone. I love the Split King feature because now my wife and I can not only have different sleep numbers but also bed positions. Thank you Sleep Number!

Rated 5 out of 5 by from Comfort We purchased our X12 about 6 weeks ago and I can say that, without a doubt, it is the most comfortable bed I have ever slept in. My husband and I have never slept better! You won't be disappointed!!!

Rated 5 out of 5 by from Great bed for bad back We've had our x12 for a year now. Love it. I hadl5/s1 herniation about 5 years ago and have had horrible pain since. Previously had to switch beds in different rooms of the night to accommodate my need, from hard to soft. Now after the x12 my back pain has been very low to nil. My wife and I love it. Im a 35 she's, a 55 sleep number. Under light is perfect. only thing that happened was our mattress cover tore at the flex split. Sleepnumber replaced it without questions and shipped it out immediately. No complaints, everything works great. Its my go to spot to read and sleep. Don't use the massage that much, but the soft bed, flex top, and light for us is heaven. Its sure expensive, but in the end, my back health and sleep is everything. I heard we are the first in San Diego to get one and we are proud of that! Thanks Sleep#.

Rated 5 out of 5 by from Best bed ever!!! We've had our X12 for 7 months now. My wife has had back pain 24/7 for 10 years. She has not been able to sleep on her side since her injury well that was before we got our x12. We've had 3 Sleep number beds before getting our x12 and have really liked them. So when my Wife wanted me to check out the x12 I wasn't really wanting to spend the money on it after all how much better could it be. I have to say after watching her lay on her side for the first time in 10 years I was amazed. When I layed on it myself I have to say it is the most confortiable bed I ever layed in. Well now after 7 months I wouldn't have any other bed. My Wife can now sleep at night and I sleep better then ever. Thank you Sleep Number! The only other thing I would have to say is if it's your frist Sleep number it can take a while to find your number and a 5 point adjustment can make all the difference. So I would reccomend call Sleep number for their help.
