Sleep Number i8 Review

Thinking of buying a new bed? Read our Sleep Number bed and mattress reviews for a smart buying decision.  You most likely know Sleep Number from the many ads and stores across America.  Sleep Number is a good bed and could be a good choice for some.  Check out our unbiased Sleep Number Mattress review to see if it will be a good choice for you.

Foam and Air Construction

  • Top Cover: A streachy soft cover that has outlast technology.  This makes the cover cool to the touch. 
  • 6″ Proprietary Foam: It is a comfort foam, and is coupled with a cooling gel layer that provides cooling relief and temperature balance.
  • Air chambers: There is 1 air chamber on each side of the bed.  This is good for being able to independentaly adjust each sides firmness level.  We have found after researching other mattresses, that having more than one chamber on each side is the best for support.  Only 1 chamber can sometimes create a hammock effect.  See our air bed comparison video for more details.

Feel

The i8 is part of Sleep Number’s innovation line. The innovation series has more comfort, and pressure relief than the classic or performance series. In addition, the innovation series also has temperature balancing benefits added to the mattress covers, as well as to the foam beneath. The classic line (c2 & c4) will have the least amount of foam, and the performance line (p5 & p6) will offer more of a plush feel than the classic series. The i8 has an inch less of comfort foam than the i10 model, but don’t let that fool you, it is a very soft bed, with just the right amount of support. You can also adjust your sleep number setting, which controls how firm or soft the air bladders are underneath the foam. The Sleep Number i8 360 smart bed has a unique balance of contouring pressure relief, with adjustablity. 

The Smarts

The i8, along with all of the beds in Sleep Number’s current line up are smart beds. What does this mean? There are sensors inside the bed that recognize your heart rate, your breathing rate, as well as how much you toss and turn during the night. This information will display for you on an app via your iPhone, Android, tablet etc., which connects to your bed via Bluetooth.  We found that the connection would often be faulty.  Keep in mind if you don’t have a strong internet connection in your bedroom you might have some issues.

The Sleep Number technology works by giving you a report, or score, of how well your night went. We did find that this technology was not consistant.  We would often toss and turn many times throughout the night and it would show as if we hadnt moved.  Sleep Number claims this technology will adjust  to maintain your comfort and pressure relief, no matter if you sleep on your side, stomach, back, or if you change positions during the night, however, we are not convinced it does. 

Motion Transfer

We found that the motion transfer was just ok with the Sleep Number i8.  We did feel a little bit of movement especially becuase there is only one chamber on each side.  

Edge Support

The edge support is not as bad as some of the other memory foam mattresses we have tested.  When we sat on the edge of the bed we noticed it does not have additional support like some other mattresses on the market today.  

Price

Sleep Number in general is very expensive for the mattress industry.  The i8 Queen is around $3299 depending on the sale they are running at the time.  That being said, you are paying for the technology they offer and the ability to try it in a brick and mortar store.

  1. Save your money. DO NOT BUY A SLEEPNUMBER BED THEY DO NOT STAND BEHIND THEIR PRODUCT THEY WANT YOU TO PAY TO HAVE IT REPLACED. To reinstall bed that is defective within less than a year. I have been back and forth with sleepnumber. My bed mattress is sunk in. Worse bed I have ever own. Run fast away from this product.

  2. We recently purchased an I8 king bed and we are disappointed in it . Our bed doesn’t adjust the way it’s advertised in fact it is totally killing my shoulder and back! Another thing they won’t let you return the frame and that’s half the price of the bed !! What are you going to do with a frame that won’t fit another bed!! Be very aware before you purchase this bed!!!!

    1. Hi Shelby, We also had the i8 with the adjustable base and now use the Airpedic with the adjustable base. We ended up ordering the remote so we could use it to adjust the frame. I have to admit the frame remote doesn’t always connect to the wifi like we would like it to but it does the job. We are much happier with the Airpedic because it offers more support than the Sleep Number. It has the additional air chamber in the lumbar region to provide the extra support needed. I hope this helps and let me know if you have any other questions.

    1. Hi Rebecca! While Sleep Number is well known, we found that having only one air bladder per side can create a hammock effect and long term issues with support and proper alignment. We would highly recommend either Air-Pedic (with 3 air chambers each side) or Rest Performance (with 5 per side). Air-Pedic is made with CertiPUR-US certified foams, so if eco-friendliness is an important benefit for you Air-Pedic is definitely your best bet. To see how they all compare check out our air bed comparison.
