seat cushion filling

The right seat cushion filling is what turns a pretty cover into a seat you actually want to sit on. Whether you are reupholstering dining chairs, building a window seat or refreshing patio cushions, the material inside sets the comfort, the shape and how long the cushion holds up.

Popular Types of Cushion Filling

Upholstery Foam

High-density foam is the go-to for chair seats and benches that see daily use. It offers firm, even support and keeps its shape over time. Lower-density foam feels softer and suits occasional seating or back cushions.

Polyester Fiberfill

Loose fiberfill gives a plush, pillowy feel and works well for chair pads, floor cushions and throw pillows. It is easy to fluff, adjust and top up as needed.

Dacron Batting

Wrapping foam in batting softens hard edges, fills out the cover and gives a smooth, professional finish.

What to Look For

• Firmness: Match density to how often the seat is used.
• Thickness: Measure your frame and cover before cutting.
• Environment: Choose quick-drying outdoor cushion foam for patios and boats.
