High-density foam features the perfect amount of cushioning and stiffness, with a compression rate of 44 lbs. It is soft yet maintains its firmness and support, allowing individuals to sit on it without excessive compression. The compression, not density, determines the firmness of the foam. To avoid a cushion that is as hard as a rock or a mattress that sinks when sat upon, one must check the compression or indentation load deflection (ILD) number. Compression refers to the number of pounds required to compress a piece of foam 25% and have it return to its original thickness. For instance, a 4-inch thick piece of foam that requires 33 lbs. to compress it by 1 inch and return to its full 4-inch thickness has a 33 lb. compression rating or ILD.

Medium-density foam is used for a firm yet relaxable cushion. It has high-quality compression and material, allowing it to last for extended periods, even when subjected to heavy weight. A 50% restocking fee may apply on returned items.
