Why is the Protect-a-bed Mattress Cover not advertised as 15" deep?
Protect-a-bed Bed Bug Mattress Cover - Cal King: Your mattress cover is advertised as 11" deep but supposedly fits up to 15" inches deep. I have a 14" deep mattress, and concerned that we may be stretching the limits of this 11" cover.
The manufacturer of the Protect-A-Bed Mattress Covers decided to use the measurement of the product before it is placed on the mattress. The covers are made to stretch and should fit very snug to ensure the effectiveness of the encasement. We have sold this cover for mattresses up to 15" for years and have never had any complaints that it ripped. If your mattress measures 14" deep, then this is the correct cover for you.
