Does your sofa sag when you sit on it to the extent that you feel as if you are sitting in a hole? If nodding, there are high chances that the lifetime of your sofa springs has lapsed and needs to be replaced. This is how to replace sofa springs.

How to Replace Sofa Springs

Although sofa springs are not very difficult to remove and replace, it requires precision and patience as the process can be lengthy.

Step #1: Gather the Necessary Tools

  • Drill
  • Bits
  • Pliers
  • Flat-head screwdriver
  • Scissors
  • Staple gun

Repair materials include:

Step #2: Locate the Sofa Springs

Many people may find this daunting as the springs are on the inside of the sofa; we’ll tell you how to locate it.

  • Turn your couch upside-down.
  • Remove its legs using hands, drill, or screwdriver to unscrew them. Whichever tool you use, turn them anti-clockwise.
  • Remove its black dust cover by either prying away the staples or cutting it.

The first method is relatively clean but could be impossible. If circumstances force you to cut it, do it carefully to avoid damaging the cover.

Only remove one side of the fabric since that’s enough to access the springs. It also saves you from unnecessary repair after the fix.

Step #3: Check the Springs

Once the inside of the coach is accessible, follow the below steps:

  • Find where the detached sofa springs are. If the springs are intact and detached from their clips, the fix will be as simple as reattaching them to their clips.
  • If need be, restore the hook shape by bending the ends. Otherwise, they might not hold onto their clips in such a state.
  • If the springs are broken, you can only fix them by replacing them. So, discard the old springs.
  • To remove the old springs, pry the clips from the stables using a screwdriver. Ensure that the screwdriver tip is under the clip, and a hammer can help you drive it.

Step #4: Check the Clips

  • Pry all the clips off one after the other. Ensure that clips are strong enough to attach to the new springs. Do so using pliers to tug them gently. 
  • Slide the loose springs ends out of the hook on the clips to detach the two.
  • Use diagonal pliers to remove bent or broken staples.
  • Confirm that the clips are strong. If not, you need to replace them as well.
  • Attach the new sofa springs to those clips.
  • Repeat that for the other side.
  • After removing the springs from the seat, remove their clips as well.

Use a drill or a driver to return the clips and use ¾ inch screws. You should use the initial staple holes to guide you as you screw the clips afresh.

Step #5: Replace the Springs

  • Hook the new springs with the clips into the latter’s circular hole. Only do so on one side.
  • Put gloves on before stretching and pulling the springs towards you.
  • Hook the other end of the spring to the clip before releasing the spring’s tension.
  • Repeat stretching and hooking for the rest of the other springs.

Stretch the fabric back to its original place over the now replaced springs. Now, staple the old black dust cover if it is still in good shape.

If not, use a new one and cut away the excess fabric with a pair of scissors. Staple it nicely using a staple guide and wide-crown stables about ¼ inch.

How Do the Upholstery Springs Work?

Upholstery springs are slightly different from the usual springs most people are acquainted with. 

For example, unlike the conventional springs that are vertical coils, they are flat yet coiled wire made of steel and running across the sofa horizontally.

The cushioning effect comes as a result of the opening and closing of the spring’s sidewinder coils.
