upholstery foam 5x24x80

A sheet of upholstery foam 5x24x80 is a practical size for long, narrow projects. At 5 inches thick, 24 inches wide and 80 inches long, it can fill a window seat, a daybed, a banquette or a long bench in one piece. That leaves you with fewer seams and a smoother finished cushion.

Why Choose a 5x24x80 Foam Sheet

A 5 inch upholstery foam sheet gives you real support without looking bulky. The 24 x 80 footprint suits many standard benches and twin-length daybeds. You can also trim it with an electric knife to fit a custom frame.

What to Look For

• Density: Higher density foam usually holds its shape longer. That matters for seating that gets daily use.
• Firmness: Firm foam works well for seats and benches. Medium or soft foam often feels better for backrests and lounging.
• Intended use: For porches and patios, look for foam that is labeled for outdoor use.

Finishing Tips

Wrap the foam in polyester batting before you add the fabric cover. Batting softens the edges and fills out the corners. It also helps the cover slide on more easily.
