upholstery foam 6x24x80

A sagging bench or flat daybed pad can make even the best fabric look tired. Upholstery foam 6x24x80 gives you a thick, generous base that fills long seating areas with support you can actually feel. At six inches deep, 24 inches wide and 80 inches long, this size suits projects where comfort and a crisp, tailored shape both matter.

Where a 6 Inch Foam Cushion Works Best

This long format covers many common seating projects in a single piece, which means fewer seams and a smoother finish under your cover fabric.

• Daybed mattress foam for guest rooms and sunrooms
• Window seat cushion foam for built-in nooks
• Long banquette, entry bench and mudroom seating
• Replacement cushion foam for worn-out furniture

What to Look For

Density and Firmness

High density upholstery foam holds its shape longer under daily use, while softer grades feel plusher but may compress sooner. Think about how often the piece will be sat or slept on.

Fit and Finishing

Measure your frame before ordering, since foam can be trimmed to fit. Wrapping it in batting helps fill out your cover and soften the edges.
