Sofa Base Repair

What You'll Need

Before we get started, here's a list of the tools and materials you'll need:

  • Measuring tape
  • Scissors
  • Plywood
  • Saw
  • Drill
  • Screws
  • Staple gun
  • Upholstery webbing
  • Foam padding
  • Fabric
  • Upholstery needles
  • Thread

Step 1: Remove the Old Webbing

First, you'll need to remove the old webbing from the sofa base. Use a pair of scissors to cut the webbing off, being careful not to damage the frame.

Step 2: Measure the Frame

Next, measure the length and width of the sofa base frame. Use these measurements to cut a piece of plywood that will fit snugly inside the frame.

Step 3: Drill Holes in the Plywood

Using a drill, make several holes in the plywood. These holes will later be used to attach the webbing to the frame.

Step 4: Attach the Webbing

Cut a length of upholstery webbing and attach it to the first hole in the plywood using a screw. Pull the webbing taut and attach it to the opposite side of the frame using another screw. Repeat this process with the remaining holes in the plywood until the webbing is securely attached to the frame.

Step 5: Add Foam Padding

Next, cut a piece of foam padding to fit the top of the frame. Place it on top of the webbing and staple it in place using a staple gun.

Step 6: Cover with Fabric

Finally, cut a piece of fabric that is large enough to cover the foam padding and webbing. Lay the fabric over the foam padding and staple it to the frame using a staple gun. Trim any excess fabric.
