You were lucky enough to inherit a memory foam mattress topper, but it’s too big for your bed. Don’t try unsuccessfully to tape the sides together, cut that foam! Cutting memory foam is not as difficult as you might expect.
Although it is possible, cutting your memory foam mattress topper with an ordinary pair of kitchen scissors will be difficult, time consuming, and leave you with painful red marks where the scissors continually hit your hand. Instead, use an electric knife! Most people have electric knives around the house to cut Thanksgiving turkey or Christmas ham. If you don’t have one, ask your neighbors.
The next step is to measure your bed. Subtract 1/4 inch from the measurement for each side and then draw those dimensions directly on the foam with a thick pen or marker. You want to cut the foam a little smaller than your mattress so you don’t have a problem fitting the sheets onto the mattress cover.
Pull the foam out onto a table, with the end you plan to cut off first just over the edge. Then use the knife as you would a turkey, nudging it slightly to cut a clean line through the memory foam. Be careful; Since you wouldn’t flip up and down with the electric knife at your family dinner, you also need to be careful when cutting through the foam. The vibrations of the knife will force you to cut straight, but if you push and pull too hard, too fast, or too hard, you’ll get jagged edges on the mattress pad.
Once you have successfully cut the first side, repeat this on the other three sides and very soon you will have a new memory foam mattress topper in the perfect size for your bed.
