upholstery foam 24x80

If you are building a long cushion, upholstery foam 24x80 gives you a generous sheet that covers most benches, window seats and daybeds in one piece. Starting with a single 24 by 80 inch slab means fewer seams, a smoother finished cushion and less trimming waste than piecing smaller cuts together.

Where a 24 x 80 Foam Sheet Works Best

This size is a natural fit for projects that are long and relatively narrow. Common uses include:

• Daybed and trundle mattress toppers
• Window seat and bay window cushions
• Dining, entry and storage bench pads
• Boat, RV and camper seating
• Headboards and padded wall panels

What to Look For

Thickness

Thinner foam suits padded headboards and decorative panels, while thicker sheets add comfort for seating and sleeping surfaces.

Density and Firmness

High density cushion foam holds its shape longer under daily use, making it a smart pick for seats that get sat on often. Softer options feel plush but may compress faster.

Easy Cutting

Foam can be trimmed with an electric knife or serrated blade, so measure your frame and cut to fit.
