What I Found from Several Live Chat Sessions
The I-8 and I-LE mattresses are very similar, but there are a few details which separate them that are worth noting. Foam Comfort Layer: The I-8 has a 3” layer of PlushFit comfort foam that is made with 7 zones specifically designed to contour to the body. The I-LE features 3” of a different type of foam called an “Exclusive Comfort Layer” with 5 contouring zones. The comfort foam layer in the I-LE is also made with breathable fabric to help keep people sleep cool throughout the duration of the night. Cooling Features: Both mattresses offer ways to keep people sleeping cool. The I-8 has temperature balancing material on the mattress cover while the foam comfort layer is made to breathe and keep people cool on the I-LE.

I-8 if…
- People Want to Spend Less. While the I-8 and the I-LE models have a lot in common, one thing they differ on is their price. A Queen size I-8 mattress retails for $3,499 while the I-LE will cost an additional $1,400 (for a total price of $4,899 for a Queen).
- People Want Full Body Pressure Relief. This is a minor difference, but the PlushFit comfort layer in the I-8 has 7 zones of body contouring and the foam layer in the I-LE only has 5 zones. People will get additional pressure relief in the lower legs and feet through the comfort layer in the I-8.

I-LE if…
- Consumers Want More Cushion. According to the Sleep Number Customer representative, I talked to, the higher the model number, the more cushioning the mattress will have. So the I-LE has an extra layer of quilting foam sewn into the mattress top and has more cushion than the I-8.

Both if…
- People Are Hot Sleepers. The I-8 and the I-LE models both offer cooling features. For the I-8, it’s through the mattress top which has built-in Outlast Technology. This technology is designed to pull moisture away from people and redistribute it throughout the night. The I-LE has an enhanced foam layer that allows for air movement and breathability.
