Alot of sleepless nights The bed is not comfortable to sleep on, we have tried everything over the years that we have had it, adding air, taking out air adding memory foam to the top of the bed and then adding a thicker memory foam to it a year later, but with avail Im going to have to just get another bed, we kept trying different things, but we have spent so much money on the dang thing we didn't want to just write it off. March 19, 2015
Waste of money When we went to sleep number, we had high expectations based on how expensive these beds are. I tried the bed in the store and decided to buy it. I am not sure if it is actually because the bed was comfortable or that I felt I could not leave the store without purchasing the c4 bed from the salesperson. After we got the bed, I immediately hated it. It literally felt like an extremely expensive air mattress. I gave the bed the benefit of the doubt and figured it would just take getting used to. Nope 2 months later it still was terrible. It would never keep my number and would constantly lose air. We decided to send the bed back but be AWARE before purchasing the bed because not only did we have to pay to have it shipped to our house for almost $200.00, we also had to pay to ship it back which was $199.00. So basically, I just completely threw $400.00 out the window for "renting" the bed for 2 months. February 8, 2015
Fantastic Bed II I am writing this updated review since I can't add to my existing. Last time I was extremely satisfied with the bed. It was fantastic. The only problem I had was with the memory foam. I called them up and within two days I received a new one. The customer service department was fantastic to talk to and treated me like I was their only customer. Just recently I was having trouble with one of my air chambers. I would put air into it and it would lose air slowly. I called up customer service and thought I would have trouble getting it taken care of. Boy was I surprised. Again I was treated fantastically and one day later (less than 24 hours) I had a brand new one at my front door. This is a company that stands behind their product, values their customers like each one is their only one. I would definitely recommend this to anyone who is thinking about getting one and to anyone who reads this. December 22, 2014
Fantastic bed (C4 King) I have had several surgeries on my lower back did not work. The bed I had before had a couple pieces of plywood that did not work. Then I purchased this little gem. Wow what a difference. Even though the bed didn't eliminate my back pain, it allows me to get a complete night sleep with extreme comfort. This bed is fantastic and I would and have recommended this bed to anyone would listen. The only flaw is the memory foam. I have had it since December of last year and its falling apart already. Maybe I got a bad one. That's why I gave it 4 stars instead of 5. But it really is a fantastic bed. September 19, 2014
love this bed ! we got the split king and love it ! love that i can raise my side and read or watch TV while hubby keeps his side flat ! love the massage feature !!! love the comfort levels and the fact that I can change mine when needed-(mine is 40 hubby is 70). highly recommend tho it is really too expensive and def should drop the price !! but I DO love it !!! July 9, 2014
I love my mattress I bought my first sleep number mattress in 2001 to replace a water bed mattress, this year 2014 I replaced that mattress with a C4 sleep number mattress. The old mattress is still good just a little worn so that went into the guest room. I have never had any problems with the first mattress except normal ware and tear the pump went out last year and I received new one at a prorated price customer service was great. I love my C4 mattress and I would recommend sleep number to all my friends. It is a little on the expensive side but that depends I guess on how much a good night sleep is worth to you. June 1, 2014
I finally found my dream mattress. My first week slept on Sleep No wasn't that comfortable. I had so much pain on my back and abs. My husband told me to give it some time at less one month for my body to adjust and get use to a new mattress. I slept so much better after two week but I still felt like the mattress was too hard and wasn't enough cushion. After two months I decided to call Sleep No customer service to return my purchased. I explained my problems to customer service that I was sinking into my mattress since my sleep no is 35 to 40. I changed my sleep no up to 50 but it was too hard and caused pain from upper to lower back. Customer service offered to send me free "Form Chamber Lift" to put under air chamber and also "Plush Form Topper" to put over air chamber to try out before I decided to return it. I excepted the offer and loved my Sleep No mattress ever since. My bed is so comfortable now with more cushions. I'm very happy with my purchased thanks to Sleep No. May 7, 2014
Not worth the big price tag! We've had our bed for two months now and regret making this very expensive purchase! We literally threw our hard-earned money in the trash. We even purchased a memory foam topper through Sleep Number to make it more comfortable and I have to admit it wasn't much of an improvement. I was told by the salesperson that we "needed" the sheet set, yet mine are still in the package unused because my current bedding set has held up pretty darn good this far! No way would I recommend any friends or family on purchasing this item, I feel stupid we spent so much money. April 29, 2014

Sagging mattress

My wife and I have gone through about 4 mattresses in the past two years, returning a couple due to early sagging at hip level. Our latest Posturepedic plush innerspring is 8 months old and sagging and it is distressful to say the least. We both are of average weight, but don't want the sagging problems and we have back and shoulder pain. We're both side sleepers

Will the SleepNumber Beds stop the sagging?

Answer: 
Hi JonS, thanks for taking the time to post your question about our beds! All of our models are built on the core of our DualAir™ Technology. DualAir™ Technology allows air to be added and removed from our Sleep Number beds. As air is added or removed, the mattress will conform to your body's natural curves. This means your mattress' firmness can be customized on each side so there is no need to compromise on comfort or support and preventing sagging like you can experience in a traditional inner spring mattress. It’s also a great idea to stop by your local store and try out the bed, to see if the feel of the bed meets your needs.

If you have more questions about our beds, please feel free to post another question, or copy the link below and paste it into your web browser anytime from 7 AM to 11 PM CT if you’d rather talk with us directly and we’ll be happy to assist you.

Answer: 
I loved the Sleep Number bed but it only stayed flat for about 18 months before it started to sag in the hip area. It is the pillow top that wears down so increasing the air pressure does not make any difference. I called the Sleep Number store and ordered a replacement mattress cover for $1500. . Again, after about 18 months the hip area broke down and I am back sleeping in a hole. Very frustrating!!!

Answers

Answer: 
Hi Diablo, my name is Alan and I work for Sleep Number. Before we get started, I want to make sure that your waterbed frame has a solid bottom that provides consistent support rather than a slat system. Frames that use slats don’t provide the support our beds need to work properly, and we highly recommend ordering a modular base for those frames.

Discounts and promotions on our beds change often and depend on the mattress model and size you’re interested in. If you’d like to get a quote on a particular bed with or without a base, please use the link below to speak with a member of our Live Chat team who will be happy to assist you.

Answer: 
Hi Jamie, thanks for taking the time to post your question about the c4 model! My name is Alan and I work for Sleep Number.

All of our mattresses and bases are made to industry standard size, so they will fit just fine in existing standard size bedroom furniture.

We don't recommend using a traditional box spring with our mattresses, as they won't support the mattress quite right. We don't prohibit the use of a box spring, however.

Our Modular Base is designed especially for the Sleep Number bed and provides the bed with the flat, firm surface it needs to provide you with the greatest amount of support for the best sleep possible.

Hello, Johnboy! My name is Alan and I work for Sleep Number. I can gladly answer your question referring to our c4 model.

The Sleep Number c4 mattress is 10" in height. The standard modular base is 8" in height, and can be placed on our standard 7 1/2" legs or our low profile 4 1/2" legs. With these different options, the overall height of the c4 bed can be either 22 1/2" high or 25 1/2" high.

Sleep Number beds are tested to at least 400 lbs per side for dual chamber beds, or at least 400 lbs total for single chambers. If the total weight you expect on the bed exceeds that, please use the link below to contact us and one of our agents will work see what options may be available to make the bed work for you.

Answers

Answer: 
Hello, Larry! My name is Alan and I work for Sleep Number. I can gladly answer your question referring to our mattresses.

We recommend our modular base, because our mattresses need a hard, flat surface to operate properly. Any hard and flat surface would work, but a traditional box spring is not recommended.

The reason the mattress needs a solid surface is because they use our DualAir technology to support your spine by pressing upwards. This means the internal air chamber needs to press against a solid surface for proper use, otherwise it would be pressing downward on a standard box spring, which actually has some give.

If you have any questions regarding the proper operation of our mattresses, please feel free to use the link below to speak with a member of our Live Chat team who will be happy to assist you. Our Chat agents are available from 7:00 AM to 10:00 PM CT every day.

Sleep position???

Is there a recommended way to sleep on the c4? When I first got the bed 5 months ago, I slept all through the night for the first few weeks and woke with no back pain. Now I toss and turn some and wake with lower back pain. I sleep mostly on my stomach, could this be why?

Answers

Answer: 
Hi LizA, that's a great question! Your Sleep Number bed can help you get great sleep whether you sleep on your back, stomach or side, but each of these positions may require you to change your Sleep Number for maximum comfort. I've personally found I need to increase my Sleep Number setting from 30 to 45 or 50 when I switch from my back to my stomach so I can get good sleep and wake up without a back ache. This could definitely be part of the reason you're not sleeping as comfortably, but it can be hard to say for sure without more information.

I'd like to get you in touch with our Sleep Specialist team so we can learn more about your situation and discuss some solutions to get you sleeping well again. Please give us a call at 1-800-472-7185 from 8 AM to 8 PM CT Monday through Friday or from 8:30-5 CT on Saturday can we can get started. We’ll look forward to working with you!

Maybe I got a bad one. That's why I gave it 4 stars instead of 5. But it really is a fantastic bed. September 19, 2014
love this bed ! we got the split king and love it ! love that i can raise my side and read or watch TV while hubby keeps his side flat ! love the massage feature !!! love the comfort levels and the fact that I can change mine when needed-(mine is 40 hubby is 70). highly recommend tho it is really too expensive and def should drop the price !! but I DO love it !!!

I love my mattress I bought my first sleep number mattress in 2001 to replace a water bed mattress, this year 2014 I replaced that mattress with a C4 sleep number mattress. The old mattress is still good just a little worn so that went into the guest room. I have never had any problems with the first mattress except normal ware and tear the pump went out last year and I received new one at a prorated price customer service was great. I love my C4 mattress and I would recommend sleep number to all my friends. It is a little on the expensive side but that depends I guess on how much a good night sleep is worth to you. June 1, 2014
I finally found my dream mattress. My first week slept on Sleep No wasn't that comfortable. I had so much pain on my back and abs. My husband told me to give it some time at less one month for my body to adjust and get use to a new mattress. I slept so much better after two week but I still felt like the mattress was too hard and wasn't enough cushion. After two months I decided to call Sleep No customer service to return my purchased. I explained my problems to customer service that I was sinking into my mattress since my sleep no is 35 to 40. I changed my sleep no up to 50 but it was too hard and caused pain from upper to lower back. Customer service offered to send me free "Form Chamber Lift" to put under air chamber and also "Plush Form Topper" to put over air chamber to try out before I decided to return it. I excepted the offer and loved my Sleep No mattress ever since. My bed is so comfortable now with more cushions. I'm very happy with my purchased thanks to Sleep No. May 7, 2014
Not worth the big price tag! We've had our bed for two months now and regret making this very expensive purchase! We literally threw our hard-earned money in the trash. We even purchased a memory foam topper through Sleep Number to make it more comfortable and I have to admit it wasn't much of an improvement. I was told by the salesperson that we "needed" the sheet set, yet mine are still in the package unused because my current bedding set has held up pretty darn good this far! No way would I recommend any friends or family on purchasing this item, I feel stupid we spent so much money. April 29, 2014

Sagging mattress

My wife and I have gone through about 4 mattresses in the past two years, returning a couple due to early sagging at hip level. Our latest Posturepedic plush innerspring is 8 months old and sagging and it is distressful to say the least. We both are of average weight, but don't want the sagging problems and we have back and shoulder pain. We're both side sleepers

Will the SleepNumber Beds stop the sagging?

Answer: 
Hi JonS, thanks for taking the time to post your question about our beds! All of our models are built on the core of our DualAir™ Technology. DualAir™ Technology allows air to be added and removed from our Sleep Number beds. As air is added or removed, the mattress will conform to your body's natural curves. This means your mattress' firmness can be customized on each side so there is no need to compromise on comfort or support and preventing sagging like you can experience in a traditional inner spring mattress. It’s also a great idea to stop by your local store and try out the bed, to see if the feel of the bed meets your needs.

If you have more questions about our beds, please feel free to post another question, or copy the link below and paste it into your web browser anytime from 7 AM to 11 PM CT if you’d rather talk with us directly and we’ll be happy to assist you.

Answer: 
I loved the Sleep Number bed but it only stayed flat for about 18 months before it started to sag in the hip area. It is the pillow top that wears down so increasing the air pressure does not make any difference. I called the Sleep Number store and ordered a replacement mattress cover for $1500. . Again, after about 18 months the hip area broke down and I am back sleeping in a hole. Very frustrating!!!

Answer: 
Hi Diablo, my name is Alan and I work for Sleep Number. Before we get started, I want to make sure that your waterbed frame has a solid bottom that provides consistent support rather than a slat system. Frames that use slats don’t provide the support our beds need to work properly, and we highly recommend ordering a modular base for those frames.

Discounts and promotions on our beds change often and depend on the mattress model and size you’re interested in. If you’d like to get a quote on a particular bed with or without a base, please use the link below to speak with a member of our Live Chat team who will be happy to assist you.

Answer: 
Hi Jamie, thanks for taking the time to post your question about the c4 model! My name is Alan and I work for Sleep Number.

All of our mattresses and bases are made to industry standard size, so they will fit just fine in existing standard size bedroom furniture.

We don't recommend using a traditional box spring with our mattresses, as they won't support the mattress quite right. We don't prohibit the use of a box spring, however.

Our Modular Base is designed especially for the Sleep Number bed and provides the bed with the flat, firm surface it needs to provide you with the greatest amount of support for the best sleep possible.

Answer: 
Hello, Johnboy! My name is Alan and I work for Sleep Number. I can gladly answer your question referring to our c4 model.

The Sleep Number c4 mattress is 10" in height. The standard modular base is 8" in height, and can be placed on our standard 7 1/2" legs or our low profile 4 1/2" legs. With these different options, the overall height of the c4 bed can be either 22 1/2" high or 25 1/2" high.

Sleep Number beds are tested to at least 400 lbs per side for dual chamber beds, or at least 400 lbs total for single chambers. If the total weight you expect on the bed exceeds that, please use the link below to contact us and one of our agents will work see what options may be available to make the bed work for you.

Answers

Answer: 
Hello, Larry! My name is Alan and I work for Sleep Number. I can gladly answer your question referring to our mattresses.

We recommend our modular base, because our mattresses need a hard, flat surface to operate properly. Any hard and flat surface would work, but a traditional box spring is not recommended.

The reason the mattress needs a solid surface is because they use our DualAir technology to support your spine by pressing upwards. This means the internal air chamber needs to press against a solid surface for proper use, otherwise it would be pressing downward on a standard box spring, which actually has some give.

If you have any questions regarding the proper operation of our mattresses, please feel free to use the link below to speak with a member of our Live Chat team who will be happy to assist you. Our Chat agents are available from 7:00 AM to 10:00 PM CT every day.

Sleep position???

Is there a recommended way to sleep on the c4? When I first got the bed 5 months ago, I slept all through the night for the first few weeks and woke with no back pain. Now I toss and turn some and wake with lower back pain. I sleep mostly on my stomach, could this be why?

Answers

Answer: 
Hi LizA, that's a great question! Your Sleep Number bed can help you get great sleep whether you sleep on your back, stomach or side, but each of these positions may require you to change your Sleep Number for maximum comfort. I've personally found I need to increase my Sleep Number setting from 30 to 45 or 50 when I switch from my back to my stomach so I can get good sleep and wake up without a back ache. This could definitely be part of the reason you're not sleeping as comfortably, but it can be hard to say for sure without more information.

I'd like to get you in touch with our Sleep Specialist team so we can learn more about your situation and discuss some solutions to get you sleeping well again. Please give us a call at 1-800-472-7185 from 8 AM to 8 PM CT Monday through Friday or from 8:30-5 CT on Saturday can we can get started. We’ll look forward to working with you!
