How To Fix Sagging Sofa Cushions At Home

 

Hack #1. Flip the cushion or repair the springs

The first solution to a sagging sofa cushion is simply flipping it. This will help prevent the pressure and wear from being concentrated on one side. Flip your cushions weekly to help keep the stuffing evenly worn down and prevent sagging.

The springs on the jute webbing might also be worn down, and addressing the bottom layer should quickly repair the dents. Bring your sofa cushions to an upholstery shop to repair the jute webbing.

 

Hack #2. Refill the cushion stuffing

Opening the sofa cushion and adding new stuffing will restore its shape and support. The cushion fill tends to flatten over time, and adding back some filling will fix the resulting sagging. So how do you restuff a sofa cushion?

Some cushions have a zipper that you can open, but you might need to cut the cover to fill the cushion. You may also have an easier time refilling the cushion by removing all the contents beforehand. Just remember to distribute the filling evenly and fluff up the cushion before putting it back on the sofa.

 

Hack #3. Sew buttons into the cushion

A hack that you might not be familiar with is restoring a sagging couch with buttons. You will cinch the cushions with several buttons to help bring them back to their support structure. By adding buttons, the stuffing in the sofa cushion will be more equally distributed and prevent sagging long-term.

Place two buttons at the front and two at the back by sewing them in with one thread. Do note that the number of buttons for cinching will depend on your cushion’s size. Then, use a single thread for all of the buttons. 

 

Can You Fix A Sagging Sofa?

You can still restore a sagging sofa by adding support underneath or replacing the stuffing. However, the best solution is to find out the reason why it sagged in the first place. Most cushions only need to be flipped, while others will be plump again when you add some more stuffing. 

If you checked the stuffing and are still in good condition, you might need to fix the springs within the frame. Over time, you have to tighten or reattach the loose springs. If they are broken, you need to reattach them together or replace the springs to restore the couch’s support.

 

How To Fix Saggy Couch Cushions That Are Attached?

It’s generally easy to fix a dented couch, especially if the cushions are removable. However, the solution won’t be as straightforward if the cushion is attached. Here is how to fix a sagging sofa due to a broken support frame. 

  1. Flip the sofa over to find the cover and remove it
  2. Check the parts to see if the framing that holds the springs is broken
  3. Get a two-inch board with the same dimensions and place it over the old one
  4. Attach the new board with wood screws to improve the sofa’s structure and solve the sagging

How To Fix A Sagging Couch Springs?

If your sofa sags because of the broken springs, you want to locate and replace them. Turn the couch upside down and move the cover underneath to help you see the frame and springs. 

  1. Remove all the broken springs and place a compressor tool on each side of the new springs
  2. Turn the tool’s handles to compress it
  3. Continue adding a spring between the supports and then remove the compression tools 
  4. Cover the couch again and secure it in place

Will Plywood Help A Sagging Couch?

Plywood can fix a sagging couch, similar to how you can fix a sagging mattress with plywood. Sagging couch cushions lose their support, and adding plywood underneath will push back the stuffing that flattens. Here is how you can use plywood for a sagging sofa.

  1. Remove all the cushions and get the dimensions of where they sit 
  2. Subtract 3 inches from the length and depth of the area and use these dimensions when cutting a piece of plywood
  3. Layer the plywood with the same size of foam rubber and cover them with a piece of cloth
  4. Place the padded foundation on the couch so the cushions will sit on the plywood side with foam
