We all love bouncy and cozy couches, which are great for an afternoon nap, an evening movie, or a pizza night. However, it is not uncommon for them to lose their elasticity over time and become saggy. In case you are dealing with a sagging couch, we bring you the complete guide on how to fix a sagging couch.

How To Fix A Sagging Couch

In the following paragraphs, we will discuss a step-by-step guide to how to fix a sagging couch.

Step #1: Collect the Tools Required

Ready yourself with generic tools like a utility knife, staple gun, a pair of scissors, pliers, flat-head screwdriver, and a driller.

You can also choose to purchase a kit of couch repair tools. These kits contain general tools and essential repair articles like matching attachment clips, serpentine springs, twine, or paper-wrapped wire.

Most likely, you will do away with the bottom dust cloth as they might be filled with cuts and fabric pills , so you must purchase new upholstery for the purpose.

Gather the necessary cleaning tools like a brush and a duster, and a disinfectant solution can also be helpful.

Step #2: Access the Insides of Your Couch

Start by turning the couch upside down. It is better to use some assistance as you don’t want to damage the nearby furniture or hurt yourself.

Once the couch is in a stable upside position, remove the legs by rotating them counterclockwise. You can either do so with your hands or use a screwdriver or a drill.

Cut away the bottom dust cover and remove it. It will be better to remove the staples and then detach the cover from the wooden frame.

Clean the insides of the couch using a brush or a duster, and you can also use the disinfectant solution on the wooden part.

Warning!

Do not use a corrosive solution to clean the wooden part of your couch. You can use a regular glass cleaning solution for the purpose, and make sure that the wood is dry before reattaching the dust cloth later. If you notice mites eating up the wood, you can use a dedicated solution to eliminate them.

Step #3: Find and Analyse the Couch Springs

Couches sag mainly due to loss of elasticity of couch springs or because of them going out of place. 

Start by finding the detached or failed couch springs and analyze whether a mere re-attachment will do the job or they need to be replaced altogether.

If the couch springs are detached, then start by reattaching them by following the steps explained further.

Otherwise, if the springs are broken, start discarding them, and you can also check the strength of existing ones by tugging them using pliers. Repeat the same procedure for clips that hold them intact.

Step #4: Reattach/ Replace the Springs and Clips

Attach the new couch springs to the clip ends of the couch and run the twine perpendicular to the springs.

You can do so by stapling the ends of each line on the frame in a “Z” shape. It is advised to follow the Z pattern as the lines may get pulled up through the staples.

Start looping the lines through each twine and let it pass through the other side of the frame. You need to be careful about the tightness of the lines from wire to wire as they should only be tight enough to hold the wire together and not so tight as to pull the twines together.

End the line as you reach the other side of the frame, maintaining the Z shape. Finally, cut the new upholstery cloth in the desired shape and dimension and staple/ sew it to the bottom of the couch. Cut the excess with a pair of scissors.

Step #5: Take Out the Cushion Foam

Your couch won’t feel like new if you don’t fix the cushions too, and you can start doing it by analyzing the level of wear and tear already done.

If the backside of your cushion is less worn out, then you can take out the foam and put it back in a reverse manner; it will restore the fluffiness.

Otherwise, it is better to keep fresh foam handy, preferably of good quality, so that the setup lasts longer. You can know more about the types of cushion foam here.

Step #6: Replace the Cushion Foam

Take out the existing foam after unzipping the couch cushion cover and turning it inside out.

It is better to put a marking on the new foam with a marker to remember the dimensions and position of the foam inside the cover. After that, put the foam inside the cushion cover and make sure that the corners are not curled up. 

Finally, slide the cover over the foam, and the newly wrapped foam should face the front. Once done, zip the cushion cover and place it as it was before.

What Leads To The Sagging Of Couch

There are several reasons which lead to the sagging of the couch. The most common ones are listed as below:

  1. Low elasticity foam: Some manufacturers don’t use good quality foams, especially for the cushion, which leads to sagging. 
  1. Springs getting loose: If the seating portion of the couch sags or gets sunken, then it is probably because of the springs getting loose.
  1. Broken springs: It happens either because the couch is too old, or the springs got damaged due to rust or any other factor. You can know more about zigzag couch spring replacement by watching this video.
