Rated 5 out of 5 by from We Love Our i8 Sleep Number Bed! My husband and I have been married 31 years, and we've never been able to agree on the firmness of any mattress. At least that was the case until we bought our Sleep Number bed. You see, I swear he enjoys sleeping on a rock, and I enjoy sleeping in a feather bed! Just by coincidence, we chatted one day with some friends who owned a Sleep Number bed. They suggested we go to a store and try the mattresses out. We soon discovered that my number is 30 and my husband's is 70. No wonder we weren't sleeping well together! We left the store that day with a signed contract. We had chosen an i8 "split king", a higher grade than we had anticipated, but we liked the idea of being able to raise and lower the head and feet. To be completely honest, I did have a bad case of buyer's remorse during the weeks before the bed arrived. I laid in our old bed at night wondering why we had spent so much money for a new bed. But...after about two weeks of sleeping on that new bed, I realized something amazing. My back no longer hurt when I woke up in the morning. The aches and pains that were constant were gone! I even mentioned it to our chiropractor, and to our surprise, he told us he owned one, too, and he was not surprised that my back was feeling so much better. We have now owned the bed for over two years, and I wouldn't trade it for the world. The neat thing is, I just recommended Sleep Number to another friend of ours, and because of her recent purchase, I've been rewarded with a $100 certificate to be used any way I want. The reason I'm on the website today is because I just turned that certificate in to buy a new set of "Winter Soft" sheets. What a nice bonus! By the way, have I told you how much I love our Sleep Number bed?!

Rated 5 out of 5 by from Great Bed I had a sleep number about 15 years ago. I bought another one a month ago. The quality has improved a lot. My husband and I have very different opinions on our style of bed and we went with a sleep number again because I like a soft bed and he prefers a firm bed. I couldn't sleep on a regular mattress because I couldn't move in the mornings and I am also allergic to memory foam so an I8 Bed was our solution. The bed is perfect for us!!!!

Rated 1 out of 5 by from Do not buy this bed This bed is more trouble than it is worth. Once it is installed, you cannot budge it. There is a gap at the top and my husband and I together cannot move the mattress up. It also sits really low. Downright ugly. The adjustable base is waaay over priced. I would love to return the whole thing.

Rated 5 out of 5 by from My Husband and I are very happy so far! We bought the floor model of the i8 just over 1 year ago. We are both sleeping much better on this bed. We change settings about once every 3 or 4 weeks just to improve our comfort. I will be contacting customer service tomorrow about the remotes but that is to be expected as they were used in store also. The only down side I have found is I wish there was better "fine control" between 30 and 45. It seems that if i could set it at 38 or so I would be much more comfortable. I think this bed was well worth the price and will be going back to Sleep Number when we need to replace it.

Rated 4 out of 5 by from Best sleep We have an I8 and the 2 in the house.The overall sleep is great so the following is a nuisance more than anything but still an issue.The I8 has stretched and sags where we always sleep.We air it up too 10 and lower it back to 40 but the sags are still there without laying back on mattress. So it's not rocket science to get that the mattress is permanently compromised. But like i said it is still best sleep we have had so i still recommend. The 2 has not had this issue......yet

Rated 2 out of 5 by from More comfortable than any other bed I have had. I have had 6 back surgeries, and got to the point that buying the cheapest bed was not possible for sleep any more. We were trying to decide, and were sure this a the ideal choice!!! Just lying on it is ok, but being om it very long, irritating!! When it is at the highest number, hard as a rok. When it is very low, less than 50, it does not get softer, it feelse like I am in a whole, just the size of my body. That was very sad!!! To buy a bed, you assume the whoe mattress will be harder/softer, yet that part is made simply for the size of the body, period, which is soooo uncomfortable!!!!!!!

Rated 5 out of 5 by from Best Sleep Ever We have been using this bed for the last 3 months and my sleep just gets better. We had some problems with the bases but sleep number was very helpful and replaced the problem bases. I have suffered with back problems for 7 years and now I can actually move in the mornings! Best birthday present ever!
