What I Found from Several Live Chat Sessions
After speaking with Sleep Number Customer Service representatives, I learned about a few extra details and clarifications that may help you decide between a C-2 or an I-8 mattress.- Firmness: By virtue of having no comfort foam layers, the C-2 is Sleep Number’s naturally firmest mattress. Yes, you can technically adjust support levels by inflating/deflating the air chamber, but with no foam in between the mattress top and the air chamber, it is going to be a firmer mattress.
- Popularity: A Customer Service representative mentioned that a magazine named the C-2 model a “Best Buy” value. So I did some research and found that Consumer Reports listed the C-2 as a Best Value mattress because its performance tested just as well in back and side support as compared to the more expensive I-8.
- Cooling Technology: Sleep Number offers several mattresses with cooling options (like the P-6 model and the M-7 model). The I-8 features a “temperature balancing sleep surface” which representatives told me is Outlast technology, designed to pull heat away from the body and redistribute it throughout the night to help people stay comfortable.
Which Should People Pick?
C-2 if…
- People Like a Firm Mattress. With absolutely no comfort foam layer in between the mattress top and the air chamber, the C-2 is Sleep Number’s firmest mattress. You can adjust the firmness by inflating/deflating your air chamber (this correlates to your Sleep Number setting) but this mattress will be naturally firm.
- People Are Looking for a Deal. Consumer Reports listed Sleep Number’s C-2 model as a “Best Value” mattress. They said that the C-2 performed just as well as in tests for back and side support as compared to the I-8 model but for a fraction of the price.
I-8 if…
- People Want Full Body Pressure Relief. The 3” PlushFit comfort foam in the I-8 is designed to relieve pressure in 7 areas of the body and the P-5 is designed to relieve pressure in only 5 areas. The I-8 adds body contouring to the knees and lower legs and the P-5 does not.
- Someone Is a Hot Sleeper. The I-8 features Outlast technology, designed to pull moisture away from you at night and redistribute it throughout the night, in the surface of the mattress.
- People Want Cushion. There is no doubt about it – when you’re comparing these mattresses, the I-8 is hands down the better choice if you like cushion over firmness in a mattress. The I-8 offers a soft pillowtop surface and 3” of PlushFit comfort foam designed to contour to your body.
