If your couch looks awful or has lost its value, then you can give it new life by adding a plywood sheet. Plywood is a thin layer of wood placed under the sofas and couches to make them more firm. 

Before buying any plywood sheet, remove the cushions from the couch and measure its dimensions. You have to buy a plywood sheet according to your couch dimensions. 

You can also cut the plywood so that it fits perfectly in the frame. Once plywood fits correctly, you can apply a layer of duct tape on areas in front of the frame, which will make the sheet more stable.

Flipping or rotating cushions is one of the convenient ways to solve the sagging issue. Sometimes the uneven distribution of weight around cushions can cause sagging. You might notice some parts of the couch sink while others don’t.

So if you have a sectional sofa, you can flip them or rotate them to reduce the sagging problem. If your sofa condition is too bad, flip the cushion once a day; otherwise, flipping a week is recommended. 

Another technique you can use to deal with such cushions is to lay them on the floor and walk over them so that fiber filling divides equally in all directions. If the cushion doesn’t feel firm, add more fiber filling it in, and again walk on cushions. 

4- Insert New Foam

Inserting new foam on the couch will also make it more valuable. If you feel more comfortable, you can use polyurethane, as it is firm and stays stable for a long time. You can also buy inserts with the exact dimensions of your cushions.

Before inserting new foam, first, remove the old one. You can also reshape or cut the new foam so it can fit perfectly in the frame. Once done, zip the cushions back and enjoy the comfortable experience.
