How to fix sagging couch cushions – 4 methods to sustain your sofa’s softness

It can be easy to think that a sagging couch cushion is a sign you need a new sofa, but there are some quick ways to fix sagging couch cushions and restore your seating to new again.

Whether you have previously invested in the best couch and want to wait to replace it entirely or are looking to re-plump your cushions to keep your living room looking elegant, there are four techniques that you could consider to breathe new life into your existing furnishings.

Shared by designers, these simple fixes are perfect for repairing your sagging couch cushions and even preventing them from sagging again, so you can have your comfy couch back without breaking the bank.

How To Fix Sagging Couch Cushions

While sagging couch cushions are often the first sign you may need to look for a new couch eventually, there are four tips you can try to improve your couch comfort quickly in the meantime that will be relatively inexpensive.


‘This simple action, while it might appear trivial, is usually the initial tactic in resolving the issue of drooping cushions,’ begins Artem Kropovinsky, interior designer and studio founder Arsight. ‘Especially if you have never flipped them before.

‘By flipping them, the stuffing is redistributed, thus helping to balance out the wear. Rotating them from one end to the other is also recommended. This rotation assists in preventing the cushions from drooping at a particular spot and being fine in another.’


If flipping and rotating your couch cushions is not enough to rejuvenate your sagging couch cushions, adding extra stuffing them is the next best bet – and is cheaper than replacing the whole pillow. You can pick up couch cushion stuffing at Walmart.

Try to match the new stuffing to the existing material in the couch, but foam will do the job if you can’t. Source some foam lengths like these foam cushion replacements at Amazon. They should be around the same length as your couch cushion, preferably slightly longer so that they can be trimmed down, and add the foam one layer at a time to each pillow, testing it with each addition until you get the proper support.

The cushion cover may be tricky to close with the new stuffing, so try not to force any zips to prevent them from ripping. Instead, have someone hold the cushion cover closed, squishing the foam, before pulling the zip closed over the top.


Couch cushions that sag are a regular part of your sofa’s life cycle and result from sitting on them all day. You can do some things to slow down the sagging.

She adds that if your budget permits, you can choose couch cushions made from high-quality natural materials at some of the top places to purchase couches. These are likely to last longer and be easier to refill and fluff in the future.

How can I make my couch cushions more supportive?

You can add extra support to your couch cushions if they are too soft. Just place some foam in the cushion cover. Unzip the cushion cover and add thin sheets of foam at a time. Test until you find your ideal firmness. The foam can also give a little structure to down cushions.

Why do couch cushions go flat?

Couch cushions can flatten out over time due to daily wear and tear. Over time, this can cause the foam to compress and become flat. This is normal and cannot be avoided, but it should only occur after several years of ownership. If you notice this happening sooner, you may be entitled to a new cushion under your sofa’s warranty.

Although there is no way of altogether preventing couch cushions from sagging, investing in a good couch (and knowing how much you should spend on a sofa to ensure longevity) and caring for your cushions correctly with regular rotations will help delay the deterioration.

The base springs of your sofa may have failed if you’ve re-plumped the cushions but still noticed the couch is sagging. Consider having the sofa restrung by an upholsterer or using a seat saver pad underneath the cushions for extra support.
