upholstery foam 4x22x80

Why Choose Upholstery Foam 4x22x80?

If you are building a long bench pad, a daybed topper or a cozy window seat, upholstery foam 4x22x80 is a smart place to start. At 4 inches thick, 22 inches wide and 80 inches long, this size covers most long, narrow seating without piecing sections together, so your finished cushion stays smooth and seam-free.

Popular Uses

• Window seat and bay window cushions
• Entryway, banquette and storage bench pads
• Daybed and trundle mattress toppers
• Boat, RV and camper seating

What to Look For

Check the density and firmness ratings listed on each product. Higher density foam generally holds its shape longer under daily use, while firmness determines how soft or supportive the seat feels. A 4 inch upholstery foam pad offers a comfortable balance for most seating, and you can trim it with an electric knife or serrated blade for a custom fit.

For a polished finish, wrap the foam in batting before adding your cover fabric. It softens the edges and helps the upholstery fabric lie neatly.
