Construction and Design

Regarding construction, the Sleep Number i8 and p6 are committed to quality and comfort. However, their design nuances set them apart. The i8 boasts a blend of memory foam and proprietary ComfortFoam, providing a plush yet supportive feel.

Comfort Features

In the realm of comfort, both the i8 and p6 excel, albeit through different mechanisms.
