How to Cut Memory Foam

Updated February 21, 2017

Memory foam is an ideal mattress topper for ultimate comfort. Stress is applied when you lie down on the memory foam. When you rise up, the stress is released. There is a molecular structure in the memory foam which allows it to maintain its shape. If the structure of the memory foam is changed or disturbed, the molecular configurations change, causing a possible negative effect in the foam over time. In order to maintain the quality of the foam, cutting it properly is important.

Spread the memory foam out on a bed. Use a pencil and a ruler to create a straight cutting line.

Cut the memory foam with an electric serrated bread knife along the cutting line.

Use an electric knife for cutting turkey or roast.

Follow the line with a sabre saw.

Cut off small slices from your memory foam with a pair of sharp scissors.


Cut your memory foam in half so it ships better if you plan to take it with you on a trip. Place Velcro strips along the edges, and reattach the foam for use after you arrive.


The least amount of cutting you must do on your memory foam, the better. Keep the cuts clean and straight to ensure longevity.
