What fill types are available for cushions?

Common cushion fills include high-density foam, memory foam, polyester fiber fill, down feathers, down/fiber blends, and spring-down combinations. Each has different cost, comfort, and maintenance characteristics.

How much fiber fill do I need per cushion?

A standard 22x22x4 inch seat cushion needs approximately 1.5-2 lbs of polyester fiber fill for a firm cushion, or 1-1.5 lbs for a softer feel. Back cushions of the same size need about 1-1.5 lbs for medium firmness.

Should I add a Dacron wrap to foam cushions?

Yes, wrapping foam in Dacron (polyester batting) softens the surface feel, rounds the edges for a more polished look, and helps the fabric slide over the cushion during installation. Use 1-inch thick Dacron for standard cushions.
