foam for couch cushions

Sagging seats can make even a beautiful sofa feel tired. The right foam for couch cushions restores support, sharpens the shape of your upholstery, and makes a reupholstery project look professionally finished. Before you cut, it helps to know what separates a cushion that flattens in a season from one that holds up for years.

What to Look for in Sofa Cushion Foam

Density

Density describes how much material is packed into the foam, and it is the best clue to durability. High density foam resists breaking down under daily use, making it the go-to choice for seat cushions that get sat on constantly.

Firmness

Firmness is about feel, not lifespan. Choose a firmer upholstery foam for seats that need to keep their shape, and a softer option for back cushions and throw pillows.

Thickness and Wrap

Measure your existing cushions before ordering replacement couch cushion foam. Many upholsterers also wrap foam in Dacron batting to soften edges and help fabric covers fit smoothly.
