upholstery foam 3x24x72
A sheet of upholstery foam 3x24x72 is one of the most versatile pieces you can keep on hand for DIY projects. At 3 inches thick, 24 inches wide and 72 inches long, it is sized to cover a full bench, window seat or daybed pad in one piece, or to be cut down into several matching seat cushions with minimal waste.
Why Choose a 3x24x72 Foam Sheet
Three inches of thickness offers a comfortable middle ground: supportive enough for everyday seating, yet slim enough to fit under most fitted cushion covers without looking bulky. The long 72-inch length means fewer seams and a smoother finished surface.
What to Look For
- Density: Higher density foam tends to hold its shape longer, which matters for seats used daily.
- Firmness: Softer foam suits back cushions and lounging; firmer foam works well for dining benches and seat bases.
- Intended use: For porches or boats, check whether the foam is suited to outdoor or damp conditions.
Tips Before You Cut
Measure your frame twice, add batting for a rounded edge, and use an electric knife for clean cuts. Ready to start your project? Browse our selection of 3x24x72 upholstery foam below.
