upholstery foam cost per cubic foot

Comparing upholstery foam cost per cubic foot is the smartest way to budget a reupholstery project, because it lets you weigh a thin back pad against a thick seat cushion on equal terms. The number on the tag reflects more than size. It reflects how the foam is made, how long it will hold its shape and how it will feel when you sit down.

What Affects Upholstery Foam Price

Density

Density is measured in pounds per cubic foot. Higher-density foam packs more material into the same space, so it usually costs more but resists sagging longer, which matters most for daily-use seat cushions.

Firmness

Firmness, often listed as ILD, describes how soft or supportive the foam feels. It is separate from density, so you can find soft foam that is still durable.

Foam Type

Standard polyurethane, high-resilience foam, memory foam and latex each fall at different points on the price scale.

How to Calculate Cubic Feet

• Multiply length by width by thickness in inches.
• Divide the result by 1,728.
• Use that figure to compare cushion foam cost across sizes.
