Foam and Air Construction of the Sleep Number i8 Mattress
- 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.
The Firmness & Feel of the Sleep Number i8 Mattress
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.
Smart Bed Technology & The Sleep Number i8
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 Performance smart 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 consistent. We would often toss and turn many times throughout the night and it would show as if we hadn’t 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 and the Sleep Number I8 Mattress
We found that the motion transfer was just ok with the Sleep Number i8. We did feel a little bit of movement especially because there is only one chamber on each side.

Common Complaints of the Sleep Number I8?
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.
