I have been searching for a bed pad that stays on the bed and doesn't pull up the fitted sheet.  I have spent a fortune trying to find the right fit for our king size bed.  Manufacturers of mattress pads and sheets are not taking into consideration the newer really thick mattresses that are on the market today.  We bought the high end Simmons Black line of mattress sets which is fantastic, but finding the proper fitting basics has been difficult. 

Pros: It fits well and stays on the mattress!
Cons: none
