firm foam

When a cushion sags after a few months, the problem is usually what is inside. Firm foam gives seats, benches, and headboards the structure they need to hold their shape, support weight evenly, and keep your fabric looking crisp and tailored.

Why Choose Firm Foam?

Softer foams feel plush at first but compress quickly under daily use. A firmer upholstery foam resists bottoming out, making it a smart pick for dining chair seats, window seats, banquettes, and bench cushions that see heavy traffic.

What to Look For

• Density: High density foam generally lasts longer and holds its shape better over time.
• Firmness: Firmness describes how the foam feels when you sit on it, separate from how dense it is.
• Thickness: Thinner pieces suit chair pads; thicker pieces suit deep seats and benches.
• Use: Consider whether the cushion will live indoors or outdoors.

Tips for a Professional Finish

Wrap your seat cushion foam in a layer of batting before adding fabric to soften the edges and fill out corners. Measure carefully and cut slightly oversized so covers fit snugly.
