How to raise couch seat cushions

Updated February 21, 2017

If your couch cushions have begun to sag or are too low, you could be doing your spine major damage. A sagging couch can cause strain to your back that increases your risk of musculoskeletal disorders, according to Mount Nittany Medical Center. However, do not assume that you have to purchase new furniture in order to solve this issue. There are ways to raise sagging or low cushions to make you and your guests more comfortable.

Lift the sofa cushions off the couch and insert a couch cushion support pad. There are many types of support pads, including simple foam supports and plastic supports. Follow the manufacturer's directions when inserting the support, since improper installation may result in discomfort.

Purchase additional couch cushions in the same size as your current cushions. Select a very firm cushion and get it upholstered in the same fabric as your couch. Insert the cushion underneath the current cushions to raise them and keep them firm. Place a non-slip cushion cover between the two cushions to keep them from sliding.

Replace the foam in the cushions with a firmer foam. You can also stuff the sides, top and bottom of the current cushions with pieces of foam to raise the current cushions without replacing all of the foam.

Bring your sofa to a professional furniture repairman and have him look for rotting or cracking in the wood support frame beneath the cushions. This can cause cushions to sink too low; once fixed, the cushions will be much higher.
