High-density foam has a compression rate of 44 lbs. It features the perfect balance of cushioning and stiffness, offering soft yet firm support that prevents excessive compression when an individual sits on it. Compression, not density, 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 ILD (indentation load deflection) number. Compression refers to the number of pounds required to compress a piece of foam by 25% while still allowing it to 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, and should not be opened with a box cutter. Instead, use a ballpoint pen or pencil to make a small incision and then break the foam from there.

Medium-density foam is used for a firmer yet still relaxable cushion. It has high-quality compression and materials to ensure long-lasting durability, even with heavy use. A 50% restocking fee may apply on returned items.
