I was excited to finally purchase a new mattress, but had no idea how difficult it would be to find a fitted sheet that would fit!  If these were a little less expensive I'd buy one to go with every set of sheets.  Currently, I own two of these fitted sheets and I just switch between the two using my old sheet sets for the top sheet and pillow cases.  Prior to this fitted sheet, I had tried several others that claimed they would fit, but did not. It wasn't even difficult to put this sheet on the bed!
