High Density Firm Upholstery Foam for Chair Cushions and Wheelchair Seats

High density foam, with a compression rate of 44lbs, offers the perfect balance of cushioning and stiffness. It is soft yet maintains firmness and support, allowing individuals to sit on it without causing excessive compression. It is important to note that compression, not density, determines firmness. To avoid cushions that are too hard or mattresses that sink when sat on, one must check the compression or ild number. Compression refers to the pounds required to compress a piece of foam by 25% and have it bounce back to its original thickness.

For example, a 4" thick piece of foam that needs 33 lbs. to compress it by 1" and return to its full 4" thickness has a compression rating of 33 lbs. or indention load deflection (ild). When purchasing foam sheets, they are sold per sheet, not per yard. It is recommended to avoid using a box cutter to open the package, instead use a ballpoint pen or pencil to make a small incision.

Medium density foam is ideal for a balance of firmness and comfort, designed to withstand heavy weight. Our foam is certified for quality with a density of 1.8, compression of 44, and 100% recovery rate. It is long-lasting and perfect for revitalizing chairs, sofas, cushions, and other high-density replacements.

Foamrush's Certipur-US Certified foam is of the highest quality, ensuring safety and durability. It can be used for various projects such as repairing chairs, creating custom cushions, and more. Our foam is easy to customize using slicing tools, allowing you to trim edges, stack layers, or glue pieces together for specific needs.

When handling foam, it is essential to open the package carefully and avoid using sharp objects to prevent damaging the foam. Unroll the foam and allow it to relax before use. Foamrush foam is versatile and can be cut and shaped to fit any project requirements.
