Replace the old couch cushion filling with new foam inserts. Standard couch cushion sizes are available in high-quality foam pieces, or you can cut a custom design to fit an irregular cushion size. Choose a foam insert for the seat and back cushions based on the firmness you prefer.
One is to add a layer of batting or cotton stuffing to the cushions to give them more support. If that doesn't work, add foam inserts under the cushion covers. Finally, if all else fails, you can buy new couch cushions that are firmer than the ones you currently have.
Sit and Lay On It—A Lot
Sit and lay on your sofa as much as possible throughout the day to squish the cushions under your weight. Bounce up and down a few times to compress the cushions and break down the foam insert a little. Shuffle the cushions around and flip them periodically so they soften evenly.
How to fix a Sagging Couch - Quick and Easy This is an easy and cheap fix if you have couch that is sagging in the middle. You just need some wood that is the thickness of the legs. Then lift the couch and slide the wood under the outside edge of the front and back. Over time the couch will straighten out.
Flip the cushions
If your sofa comes with reversible sofa cushions, regularly flipping them will help to preserve the life of your sofa as it will prevent the cushions from sagging, allowing them to keep their shape. Sofa cushions should be turned every 1-2 weeks to help stop them sinking.
Perhaps your sofa cushions are sagging, or the fabric is looking stained and worn? If this sounds familiar, don't worry – it's bound to happen. While the average sofa should last between 7 and 15 years, signs of wear and tear are likely to appear before then – especially if it's a well-loved sofa.
If after you rinse the couch you find it is still stiff then try getting a clean textured towel and rubbing it all over your couch. It should loosen up those stiffened flat fibers and start feeling soft again. If you have a bristled brush that's kind of soft but not hard then that will likely help to.
Chances are, your sofa doesn't need replacing — it just needs a refresh! Swapping out the foam inserts in your couch cushions is an easy and effective way to transform saggy, flattened cushions into plush, comfortable seating once again.
If you have an uncomfortable sofa, invest in quality pillows to help balance out the situation. “Large, fluffy pillows with feather-down inserts are an easy way to make your sofa feel a bit softer,” says designer Maggie Griffin.

Fix Flat Cushions
Replace the foam in flattened seat cushions with new foam from a local upholsterer or upholstery supply store, says Herzog. Look for sheets of medium-density foam, often the most comfortable for seating, which you'll cut to fit your cushion covers.
To make your sofa firmer, replace your cushion filling with higher-density foam and batting. You can also secure a piece of plywood between the couch frame and the cushions, which adds extra support. Note: This won't work for couches with cushions that are permanently attached.
a brand new sofa cushion with a hardness of 200 Newtons will be extremely hard on day one, however after several weeks of use you will find it start to soften off a little; after several years of use it will have softened considerable compared to when it was brand new.
