Why Choose a High Density Foam Cushion?

A high density foam cushion is the foundation of any seat that needs to stay comfortable and supportive for years. Whether you're reupholstering dining chairs, building a window seat, or tackling a foam cushion replacement on a worn sofa, dense foam resists sagging and holds its shape far longer than softer, lower-quality fillings.

What to Look For in Upholstery Foam

• Firmness: Firm seat cushion foam suits benches and dining chairs, while a medium feel is often more comfortable on lounge seating and sofa cushions.
• Thickness: Thicker foam padding for chairs and sofas adds everyday comfort, while thinner sheets work well for headboards and chair backs.
• Location: For patio and porch projects, choose outdoor cushion foam designed to drain and dry, and pair it with weather-resistant fabric.

Tips for a Professional Finish

Wrapping your foam in polyester batting softens hard edges and helps the cover fabric fit smoothly without wrinkles. Measure your frame carefully, and consider cutting the foam slightly larger than the cover so it fills the fabric for a crisp, tailored look.
