Upholstery Foam High Density Firm Foam Soft Support (Chair Cushion Square Foam)

The compression rate of high-density foam is 44lbs, making it the perfect balance of cushioning and stiffness. It remains soft while still providing firmness and support, allowing individuals to sit without causing the foam to compress too much. Firmness is determined by compression, not density. To avoid overly hard cushions or sinking mattresses, it is important to check the compression or ild number.

Compression refers to the pounds needed to compress the foam by 25% and then bounce back to its original thickness. For instance, a 4" thick foam piece that requires 33 lbs to compress it by 1" before returning to 4" thickness has a 33 lb compression rating or ild (indentation load deflection). Foam sheets are sold per sheet, not per yard. To open, avoid using a box cutter and instead use a ballpoint pen or pencil to make a small incision.

This high-density foam is durable, lasting 7 to 10 years. It provides firm yet comfortable cushioning, making it ideal for various uses such as oval and round poker tables, furniture cushions, boat cushions, car cushions, foam mattresses, and bedding support. The medium-density foam is designed to withstand heavy weight while maintaining quality compression for extended periods.

Proudly made in the USA, this foam has a density of 1.8 and a compression rate of 44lbs. With a 100% recovery rate, it can last from 3 to 7 years. Contact us for any custom cut needs you may have.
