Foam and Air Construction

  • Top Cover: A stretchy 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 independently 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 for more details. 

Firmness & 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, while still offering 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. If you want all of the technology without the connection issues check out our review of the ReST bed. 

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.  

Overview

Sleep Trial

Sleep Number beds come with a 100 night sleep trial.  After 30 days if you are not completely satisifed with your purchase you can return/exchange it.  It does appear that you may be required to pay return shipping fees.  The sleep trial applies to the bed only, adjustable bases are considered final sale and not eligibile for a refund.  To read more about the sleep trial click here.

Warranty

Sleep Number comes with a 25 year limited warranty. 

Shipping

Sleep Number beds require white glove delivery (delivery and set up of your mattress and base) for a fee of $199.

Pricing

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.

Is the Sleep Number i8 right for you?

We recommend the Sleep Number i8 mattress if:

  • You want a variety of options to choose from, Sleep Number has an extensive lineup available.
  • You and your partner prefer different firmness settings and want dual adjustability.

The Sleep Number i8 might not be the right fit if:

  • You and your partner like to snuggle up, unlike other air beds we have reviewed sleep number does not have a reinforced support bar between the two air chambers.  This left couples rolling into the center of the bed while the air dispelled to the outer edges. 
  • You’re looking for a budget mattress.

Common complaints

Lack of transparency from Sleep Number seemed to be a leading complaint.  If you are thinking of purchasing a sleep number we would strongly advise you thoroughly read through their warranty and sleep trial conditions.  As we mentioned earlier, while the mattress is eligible for 100 night sleep trial, this does not include the adjustable base which is considered final sale. 

We’ve also seen a number of complaints regarding Sleep Number standing behind their warranty, with hidden fees and service issues being a leading gripe.

Lastly, we’ve seen a number of complaints regarding sagging and discomfort of the mattress over time.  We strongly recommend an air bed that offers multiple air chambers per side with the ability to adjust the lumbar region independently from the neck and shoulder and hips and legs.  We also encourage looking for an air bed that has reinforced foam support between the 2 sides of the bed.  This will eliminate partners rolling into the center of the mattress.

    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.

    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!!!!

      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.

    What bed do you like as opposed to this one?
    Thanks!

      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.
