How to Replace Couch Cushions With Memory Foam
- 1). Measure the length, width and depth of your couch cushions, and note them on paper. Visit a bedding store, and purchase precut memory foam that matches your cushion's dimensions.
- 2). Open the couch cushions. Your cushion should be secured by either a zipper or stitching. If your cushions are stitched, release the threading with a seam ripper.
- 3). Remove the old foam or stuffing. You can throw it away or save the foam for future craft projects.
- 4). Insert the memory foam into the cushion casing. Zip up the cushion if it has a zipper. If you released the threading with a seam ripper, make a 1/2-inch fold of the upholstery material and secure it with pins spaced 2 inches apart. Stitch the edge with a thread and needle to fully secure the new memory foam insert. Place the cushions on the couch.
