Foam and Air Construction of the Sleep Number i8 Mattress
- Mattress Cover: This is a soft, stretchy cover that utilizes outlast technology. This makes the cover cool to the touch.
- 6″ Proprietary Foam: This comfort foam layer is coupled with a cooling gel layer that provides cooling relief and temperature balance.
- Air chambers: Sleep Number beds are made with one air chamber on either side of the bed. This allows sleepers to adjust the firmness level of each side of the bed independently.
The Firmness & Feel of the Sleep Number i8 Mattress
The i8 is part of Sleep Number’s innovation line. The innovation series provides more comfort and pressure relief than either the classic or performance series. In addition, the innovation series has temperature balancing benefits added to the mattress cover, as well as to the foam beneath.
The i8 has an inch less 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 adjust your Sleep Number setting, which controls how firm or soft the air bladders are underneath the foam. This is good for being able to adjust each side’s firmness level independently.
The Sleep Number i8 360 smart bed has a unique balance of contouring pressure relief, with a wide range of adjustability. However, we have found after researching other mattresses, that adjustable air beds with more than one air chamber on either side, such as Air-Pedic, offered superior support and targeted stubborn pressure points more effectively.
When placing our weight upon the air chambers we could feel the air dispersing towards our head and feet, causing sagging through the mid-section. This was more apparent the softer our number setting. Ultimately, the single air chamber design found in the Sleep Number beds had a tendency to create a hammock effect. See our air bed comparison for more details.
Other Popular Sleep Number Models
Both the c2 & the c4 are part of Sleep Number’s classic line. These mattresses are the most affordable of the adjustable air beds offered by Sleep Number. The firmest beds in the collection, the comfort layer of the c2, and the c4 are made with a thinner layer of foam than the plusher comfort layers found in the performance line(p5 & p6).
Smart Bed Technology & The Sleep Number i8
The i8, like the rest of the Sleep Number beds, is a smart bed. Smart beds, like Sleep Number and the Pod Pro by Eight Sleep, can provide valuable feedback on your sleep, as well as your overall health.
Sensors inside the bed recognize your heart rate and 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 acts as a remote control and connects to your bed via Bluetooth.
We did find that the connection was often faulty with Sleep Number. 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 you slept. 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. I have noticed this inconsistency in other smart beds we’ve reviewed and I believe it may be due to rolling onto your partner’s side of the bed, occasionally causing the sleep tracking to report incorrectly.
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.
Is The Sleep Number i8 Good For Couples?
Couples run into some unique challenges when shopping for a mattress. While adjustable air beds are a great choice for couples with different firmness preferences it is only one factor that may affect your sleep experience when sharing your bed with a partner.
Motion Transfer and the Sleep Number I8 Mattress
Motion Isolation, or motion transfer, refers to the bed’s ability to isolate motion. If you are a light sleeper with a tendency to wake up when your partner moves around, you likely already know how important this is.
We found that the motion transfer was ok on the Sleep Number i8. It wasn’t the best we’ve experienced, nor was it the worst. We did feel a little bit of movement, likely due to the single air chamber design. Additionally, the Sleep Number beds are not made with reinforced foam support in the center of the mattress. This did create some problems with us rolling into the center of the bed.

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 a 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.
As well as a number of complaints regarding sagging and discomfort of the mattress over time. While minor indentations and wear and tear are common in older mattresses, Sleep Number consumer reviews seem to indicate an unusual amount of degradation.
Lastly, 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 either side of the bed. This will eliminate partners rolling into the center of the mattress.
