Step 1
Remove the old vinyl upholstery by removing the staples and upholstery tacks that hold it to the couch. Use needle-nose pliers to gently pull them away. Gently pull away the fabric, making sure not to rip it as it will be used as a template for the new vinyl fabric.
Step 2
Remove the old batting from the couch cushions. Remove the old upholstery tacks with the pliers. Insert new batting, and secure it by hammering in new upholstery tacks with a mallet.
Step 3
Place the old vinyl fabric on top of the new fabric. Cut around the old fabric with scissors, leaving about 3 inches of additional fabric around the outside edge.
Step 4
Move the couch onto its backside. Pull the new vinyl fabric onto the couch frame. Staple the new vinyl with a staple gun along the frame, leaving 2 inches between each staple.
Step 5
Drape the dangling fabric over the arms of the couch. Fold the fabric closest to the back of the couch forward. Cut a slit in the middle of the upholstery fabric and wrap the fabric over the back of the couch's arm. Staple it into place with a staple gun, making sure to leave 2 inches between each staple.
