High-density foam features the perfect amount of cushioning and stiffness, with a compression rate of 44 lbs. It is soft but 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. If you don't want a cushion that's hard as a rock or a mattress that sinks when you sit on it, you need to check the compression or ILD (Indentation Load Deflection) number. Compression refers to the number of pounds necessary to compress a piece of foam 25% and still have it bounce back to the 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. It is important to avoid using a box cutter to open the packaging and instead use a ball-point pen or a pencil. Start by making a small incision and then break the foam from there. The durability of high-density foam is excellent, as it can last for 7 to 10 years.

Medium-density foam is used for firmness yet relaxable cushions. It has high-quality compression and material that helps it last for longer periods of time, even when subjected to harsh weight. This 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 rate. It has a 100% recovery rate and can last from 3 to 7 years. If you have any custom cut needs, you can contact the manufacturer for assistance.
