How to Cut Memory Foam Toppers

Memory foam mattresses and mattress toppers are becoming increasingly popular as alternatives to traditional spring mattresses in the bedroom. One of the major benefits of memory foam is its ability to mold to the shape of your body, creating what some consider to be a more comfortable night's sleep. Memory foam mattresses and toppers often only come in a few limited sizes, however, and you may wish to cut the foam to fit a smaller bed such as a twin bed.
