upholstery foam 36x72

A sheet of upholstery foam 36x72 is one of the most versatile supplies you can keep on hand for reupholstery and DIY seating. At three feet wide and six feet long, it's large enough to cover a daybed, window seat or banquette in one piece, yet easy to trim into smaller cushions for chairs, ottomans and headboards.

Why Choose a 36 x 72 Foam Sheet

Working from a full sheet means fewer seams, less waste and a smoother finished surface under your fabric. It also lets you cut matching cushions from the same material, so every seat feels consistent.

What to Look For

Thickness

Thinner foam suits headboards, chair backs and padded panels, while thicker sheets are better for seat cushions, benches and floor mattresses where comfort and support matter most.

Density and Firmness

High density upholstery foam holds its shape longer under daily use, making it a smart pick for dining benches and frequently used seating. Softer foam offers a plush feel for back cushions and accent pieces.

Wrapping and Fabric

• Add a layer of batting for rounded edges.
• Pair with durable upholstery fabric for high-traffic seats.
