Why Choose Upholstery Foam 24x24 Squares

Upholstery foam 24x24 is a go-to size for refreshing dining chairs, ottomans, floor cushions, and outdoor seating. A 24-inch square gives you enough room to cover a standard seat with extra for trimming, so you can cut a custom shape without buying a full roll of cushion foam.

What to Look For

Thickness

Thinner seat cushion foam works well for chair seats and padded headboards, while thicker cushion foam suits benches, window seats, and floor pillows where you want deeper support.

Density and Firmness

High-density foam holds its shape longer under daily use, making it a smart pick for seating that sees heavy wear. Softer foam feels plush and is better for backrests and decorative pieces.

Intended Use

For patio or boat cushions, look for foam designed for outdoor conditions that drains and dries quickly. For indoor furniture, consider wrapping your foam square in polyester batting for a smoother, rounder finish under your upholstery fabric.

Find Your Foam
