High-density foam features a compression rate of 44 lbs, offering the perfect balance of cushioning and stiffness. It is soft yet maintains its firmness and support, preventing excessive compression when an individual sits on it. 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 consider the compression or ILD (indentation load deflection) number. Compression refers to the number of pounds required to compress a piece of foam by 25% and have it bounce back to its original thickness. For instance, a 4-inch thick piece of foam that requires 33 lbs to be compressed by 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, and should be opened carefully, without using a box cutter, but rather a ball-point pen or pencil to make a small incision and then break it from there.

Medium-density foam is used for a firm yet relaxable cushion. It has high-quality compression and materials that allow it to last for extended periods, even under heavy weight. A restocking fee may apply on returned items.
