Sagging sofas usually fall into two categories: those that you got from a friend or relative (or the curb) for free and wouldn’t necessarily have chosen yourself, but the price was right; or a worn and popular piece of furniture that is really past its heyday but is so comfortable that you can’t get rid of it. Even if it is demoted from the living room to the basement or playroom, it is still something that you want to have in your home.

Fortunately, there are a few ways to extend the life of your sagging couch, courtesy of Lee Wallender at The Spruce. Here’s what you should know.

Why your couch sags

This sagging in your sofa is usually caused by sagging pillows, loose or broken springs, or a combination of the above. Wallender writes. (There can also be problems with the wooden frame, but that’s too big for us today.)

If you’re not sure what type of slack you’re dealing with, remove the pillows from the couch and see if the remaining pieces are straight or still curved. Then determine if you need to fix the pillows, the springs, or both.

How to fix sagging pillows

At this point, we’re assuming you’ve already done the obvious: see if flipping or repositioning the foam in the pillows helps. If not, your best bet is to buy new foam and refill the pillows. Wallender offers Step by step instructions for doing that.

How to reattach or replace couch springs

Sometimes couch springs slip out of their clips and just need to be reattached. Sometimes they can even break and need to be replaced. Either way, start by turning the couch upside down, then unscrewing the legs (if possible) and removing the dust cover from the bottom of the frame.

Wallender also offers Step by step instructions how to reattach and replace the springs, plus a list of the tools you will need for each job to get you through the project.
