How to Cut Foam Mattress Pads

Foam mattress pads come in various thicknesses and sizes to accommodate all mattress sizes. They lay on top of a mattress to make it firmer or softer, depending on the density of the foam pad. If you have a foam mattress pad that is larger than the size of your mattress, you must cut it down to size. To cut a foam mattress pad, you can use an electric knife to slice through the foam quickly without shredding it.

Tape measure
Marker
Plywood or cardboard
Electric knife
Saber saw with foam blade (optional)
