High Density Firm Upholstery Foam for Chair Cushions, Wheelchairs - 5 x 31 x 31

High density foam has a compression rate of 44lbs, providing the perfect combination of cushioning and stiffness. It maintains its firmness and support, allowing individuals to sit without causing the foam to compress too much. The level of compression, not density, determines firmness. To avoid overly hard cushions or sinking mattresses, it is essential to check the compression or ild number.

Compression refers to the amount of pounds needed to compress a piece of foam by 25% and have it bounce back to its original thickness. For instance, a 4" thick foam piece that requires 33 lbs to compress it by 1" and return to 4" has a compression rating of 33 lbs or (ild) - indention load deflection. Foam sheets are sold per sheet rather than per yard, and caution should be taken when opening them to avoid using a box cutter. It is recommended to use a ballpoint pen or pencil to make a small incision and proceed from there.

In terms of durability, the foam will last 7 to 10 years. Medium density foam is designed for firm yet comfortable cushioning with high-quality compression that ensures a longer lifespan even under heavy weight. This foam is made in the USA and is suitable for a variety of uses such as oval and round poker tables, furniture cushions, boat cushions, car cushions, foam mattresses, and bedding support.

The density of the foam is 1.8 with a 44lb compression, offering a 100% recovery rate and lasting from 3 to 7 years. For custom cut needs, please contact us.
