In 1959, an African American woman by the name of Bertha Berman patented a design for fitted sheets that had corners sewn in a way that would fit the sheet to the mattress. These sheets were still less than perfect as they still managed to pop off the bed.
The fitted bottom sheet has extra wide elastic that fits over the edges of the mattress. This sheet easily accommodates a very thick mattress. The fabric is very comfortable. I bought a California king sheet set and a full size set and both sets are great. I highly recommend these sheets.
