Medium density 4x24x72 MDF foam for upholstery, semi firm, white

The compression rate of Medium Density foam is 36lbs, providing the ideal balance of cushioning and stiffness. This foam is soft yet maintains firmness and support, allowing individuals to sit without excessive compression. Firmness is determined by compression, not density. To avoid overly hard cushions or sinking mattresses, check the compression or ILD number. Compression refers to the pounds needed to compress foam by 25% and regain its original thickness. For instance, a 4" foam piece needing 33 lbs. to compress it by 1" and return to 4" has a 33 lb. compression rating or ILD.

Foam sheets are sold per sheet, not per yard. Use a ballpoint pen or pencil instead of a box cutter to avoid damage.
