# How to Cut Foam for a Seat
A pair of sharp scissors or a utility knife will cut through thick polyfoam used to upholster seats, but the foam edges will be uneven and hard to cover. Using scissors or a utility knife will also require heavy pressure, a sawing motion and a bit of elbow grease. The trick to getting a smooth edge when cutting the foam for a seat is to use an electric knife. An electric knife will slide through the foam almost as easily as a hot knife slides through butter.
Things You'll Need
- Colored chalk
- Electric carving knife
Instructions
-
-
1
Place the polyfoam on a flat surface.
-
2
Mark the shape of the seat on the foam with chalk, making a heavy, clearly visible line.
-
3
Position the electric knife at a 90-degree angle to the foam, at the outer edge of the chalk line, making sure there is nothing under the area you will be cutting.
-
4
Turn the knife on, and cut all of the way around the chalk line, keeping the knife blade straight up and down in the foam.
-
5
Set the excess foam aside, and inspect the seat pad for uneven edges. If you find uneven edges, trim the rough spots away with the electric knife.
