High-density foam features the perfect amount of cushioning and stiffness, with a compression rate of 44 lbs. It is soft yet still holds its firmness and support, ensuring an individual can 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 instance, 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.

It's important to note that all foam sheets are sold per sheet, not per yard. When cutting the foam, it's recommended to use a ball point pen or a pencil instead of a box cutter. Start by making a small incision and then break it from there.

Medium-density foam is used for a firmer yet relaxable cushion. It has high-quality compression and material, allowing it to last for longer periods of time even when subjected to harsh weight. This foam is made in the USA and is ideal for use in oval and round poker tables, furniture cushions, boat cushions, car cushions, foam mattresses, and bedding support.

The medium-density foam has a density of 1.8 and a compression rate of 44 lb. It offers a 100% recovery rate and can last from 3 to 7 years. If you have any custom cut needs, don't hesitate to contact the manufacturer.
