Types of Foam in Couches

Polyurethane

• Foam couch cushions are made out of polyurethane, which is both durable and affordable. Polyurethane is available in various densities and will vary in its durability and comfort depending on the quality of the foam.

High-Resilient Foam

• Good Housekeeping recommends choosing a high-resilient (HR) polyurethane foam, which is both durable and comfortable, although more expensive. Couches with this type foam should have labeling that indicates the presence of HR foam. This type of polyurethane foam is designed specifically for longevity.

Combinations with Other Materials

• Foam cushions are usually padded with either another layer of polyurethane, cotton batting, or a polyester fiber filling. For those that prefer a firmer and more quality cushion, Dr. Leona Hawks of the Utah State University Cooperative Extension suggests choosing a sofa with high-resilient foam padded with a layer of down feathers or one with polyester batting surrounding a polyurethane foam base.

Foam Density

• When choosing a sofa or couch, inquire about the foam's density. High-density polyurethane will last longer, but it is also harder feeling. Alternately, while low-density foam is softer to the touch, it will not last as long. A foam's density indicates how much foam is used per cubic foot. Those with lower densities have more filler materials and air within the foam. Linda Reese Adler, writing from the University of Kentucky's Cooperative Extension Service, recommends choosing a foam with a density of at least 1.8 pounds per cubic foot.
