High Density Firm Upholstery Foam for Chair Cushion & Wheelchair Seat

Foam with a high density has a compression rate of 44lbs, providing the perfect combination of cushioning and stiffness. This type of foam is soft yet retains its firmness and support, allowing individuals to sit on it without the foam becoming overly compressed. Firmness is determined by compression, not density. To avoid cushions that are too hard or mattresses that sink under pressure, it is important to consider the compression or ILD number.

Compression refers to the amount of force required to compress a piece of foam by 25% and then return it to its original thickness. For example, a 4" thick piece of foam that needs 33 lbs of force to compress it by 1" and have it bounce back to 4" has a compression rating of 33 lbs or (ILD) - indentation load deflection. When purchasing foam sheets, they are sold per sheet, not per yard. It is recommended to open the package with a ballpoint pen or pencil to avoid damaging the foam with a box cutter.

Medium density foam is ideal for firm yet comfortable cushions, with durable compression and high-quality materials that can withstand heavy use. Our foam, certified for quality, has a density of 1.8, compression of 44 ILD, and a durable recovery rate. It is perfect for refreshing chairs, sofas, cushions, and other high-density foam replacements. Designed to provide the right balance of support, comfort, and longevity, our high-density firm foam is suitable for high-traffic areas and long-term use.

Foamrush products are CertiPUR-US certified for quality assurance, guaranteeing safe and non-toxic materials that benefit both your health and the environment. Our foam can be customized for various projects, such as repairing chairs, creating custom cushions, or even crafting unique items like headboards or boat seats. With the ability to easily customize our foam using common cutting tools, customers can create the perfect size and shape for their needs. It is important to handle the foam with care, allowing it to fully expand for a few days before cutting to size.
