Mattress Protectors come in a range of functions, including waterproofing your mattress, or for hypoallergenic purposes. It is possible to get a number of mattress protectors that fit your mattress just like a fitted sheet, or alternatively, some people prefer protectors that encase the whole mattress. These tend to be better for things like bed bugs, but can be much harder to clean than the fitted sheet type of mattress protector.
