Upholstery Foam High Density Firm Foam Soft Support (Chair Cushion, Wheelchair Seat Cushion)

High-density foam features the perfect amount of cushioning and stiffness, with a compression rate of 44 lbs. Its soft, yet still holds its firmness and support, allowing an individual to sit on it without compressing the foam too much. Compression, not density, is what determines the firmness of the foam. If you don't want a cushion that's as hard as a rock or a mattress that sinks when you sit on it, you need to check the compression or indentation load deflection (ILD) number. Compression refers to the number of pounds necessary to compress a piece of foam 25% and still have it bounce back to its original thickness. For example, a 4-inch thick piece of foam that requires 33 lbs. to pack it down 1 inch and return to its full 4-inch thickness has a 33 lb. compression rating or ILD.

All foam sheets are sold per sheet, not per yard. To open the package, do not use a box cutter; instead, use a ballpoint pen or a pencil. Start by making a small incision and break it from there. The durability of high-density foam is impressive, as it can last 7 to 10 years.

Medium-density foam is used for a firmness that is still relax-able. It has high-quality compression and material, allowing it to last for longer periods of time, even when harsh weight is applied. This type of foam is made in the USA and is ideal for a variety of applications, including oval and round poker tables, furniture cushions, boat cushions, car cushions, foam mattresses, and bedding support.

The density of this medium-density foam is 1.8, with a 44 lb. compression rating. It has a 100% recovery rate and can last from 3 to 7 years. If you have any custom cut needs, please contact us for assistance.
