upholstery foam for diy

Start Your Project With the Right Foam

Choosing the right upholstery foam for DIY projects makes the difference between a cushion that holds its shape for years and one that sags after a season. Whether you're reupholstering dining chairs, building a window seat, or padding a headboard, the foam underneath your fabric does most of the work.

What to Look For

Density

Density tells you how durable foam will be. High density foam is the go-to choice for seat cushions and benches that see daily use, while lighter foam works well for backs, headboards, and decorative pieces.

Firmness

Firmness is about feel, not lifespan. Pick a firmer seat cushion foam for upright dining chairs and a softer option for lounging or back support.

Thickness

Match foam thickness to the piece:

• Thin foam for chair pads and headboards
• Medium foam for dining seats and bench cushions
• Thicker foam for sofa seats and window seats

Find Your Foam
