High density foam has a compression rate of 44lbs, providing the perfect balance of cushioning and stiffness. It remains soft while retaining firmness and support, allowing individuals to sit without sinking too much. Compression, not density, determines firmness. To avoid extremely hard cushions or sinking mattresses, check the compression or ild number. Compression refers to the pounds required to compress foam 25% and have it bounce back to its original thickness. For instance, a 4" thick foam needing 33 lbs. to compress 1" and return to 4" has a 33 lb. Compression rating. Foam sheets are sold per sheet, not per yard.
