upholstery foam polyurethane

The right upholstery foam polyurethane can make a tired chair, sagging sofa, or bare bench feel brand new. Polyurethane foam is the go-to filling for seats, backs, and headboards because it holds its shape, cuts cleanly, and comes in a wide range of firmness levels to suit almost any project.

Why Choose Polyurethane Foam for Upholstery

Polyurethane foam for cushions balances comfort and support while staying lightweight and easy to work with. It is a practical choice for both first-time DIYers and experienced upholsterers tackling a full reupholstery job.

What to Look For

Density

Density relates to durability. High density upholstery foam generally holds up better on seats that get daily use, while lighter foam can work well for backs and decorative pieces.

Firmness

Firmness affects how the seat feels. Consider who will sit there and how often:

• Firm upholstery foam for dining chairs, benches, and window seats
• Medium foam for sofa seats and everyday lounging
• Soft foam for back cushions and pillow-style comfort

Thickness and Size

Measure your frame or old cushion carefully so your replacement cushion foam fits snugly under your fabric.
