upholstery foam warehouse

Whether you're rebuilding a sagging sofa or sewing custom bench cushions, our upholstery foam warehouse puts the right filling at your fingertips. Good foam is the hidden foundation of every comfortable seat. It shapes how a cushion feels, how well it holds up, and how polished your finished fabric looks.

Choosing the Right Cushion Foam

Not all upholstery foam is created equal. Before you buy, think about how the piece will be used and who will sit on it.

What to Look For

• Density: High density foam resists flattening and suits everyday seating like dining chairs and sofas.
• Firmness: Softer foam feels plush for backrests, while firmer foam supports seat cushions.
• Thickness: Match the depth of your existing cushion or frame for a clean, tailored fit.
• Use: Indoor, outdoor and decorative projects each call for different foam types.

Tips for a Professional Finish

Wrap foam sheets in batting before covering them to soften edges and help your upholstery fabric drape smoothly. Measure twice, and cut with an electric knife or serrated blade for straight, even sides.
