This outer shell is 11” tall to allow for the 5” of comfort foam that Sleep Number puts into the 360 i7 Smart Bed model. If you decide to add an inch of foam to your P5 model, this cover is a great way to upgrade your P5 into the thickness of a i7! These covers are guaranteed to fit perfectly. We use heavy weight fabrics, Kevlar thread.
