Why Choose Upholstery Foam 2.8 Density?

When a cushion needs to hold its shape for years, upholstery foam 2.8 density is one of the most reliable choices you can make. Weighing about 2.8 pounds per cubic foot, this high density upholstery foam resists sagging and body impressions far better than lighter grades. That makes it a favorite seat cushion foam for sofas, dining chairs, window seats and banquettes that see daily use.

Density vs. Firmness

Density measures how much material is packed into the foam, and it is the main driver of durability. Foam firmness, often listed as ILD or IFD, describes how soft or supportive the cushion feels when you sit. A 2.8 lb foam can be made in softer or firmer versions, so you can match comfort to the project without giving up longevity.

What to Look For

• Thickness: 4 to 6 inches suits most seat cushions, while thinner sheets work well for backs and headboards.
• Feel: choose firmer cushion foam for seats and softer foam for backs and pillows.
• Wrapping: a layer of polyester batting gives a rounded, finished look under your upholstery fabric.
