upholstery foam 24x120

When a project runs long, upholstery foam 24x120 saves you from piecing together short slabs. A single 24-inch by 120-inch sheet covers a full built-in bench, a deep window seat, or a run of banquette seating in one continuous piece. That means no seams, fewer weak spots, and a smoother finish under your fabric.

Why Choose a 24 x 120 Foam Sheet

Long upholstery foam is ideal for spaces where standard cushion sizes fall short. Common uses include:

• Kitchen and dining banquettes
• Window seat cushions and reading nooks
• Entryway and mudroom benches
• Boat, RV, and daybed seating

What to Look For

Thickness

Thinner sheets work well for back padding and decorative tops. Thicker foam gives seats that see daily use more depth and comfort.

Density and Firmness

High density foam holds its shape longer and resists sagging, making it a smart pick for bench cushion foam. Softer options suit lounging and occasional seating.

Easy Trimming

Foam is simple to cut down with an electric knife, so you can tailor a long sheet to your exact length.
