This foam provides the right balance of cushioning and firmness. It’s soft but retains its firmness, making it suitable for heavy traffic and high-use applications.Compression = Firmness: Compression, not density, determines firmness. To avoid cushions that are too hard or mattresses that sink too much, check the compression or ILD (Indentation Load Deflection) number. Compression indicates the number of pounds required to compress the foam by 25% while still returning to its original thickness. For example, a 4" thick foam that needs 35 lbs to compress by 1" and return to 4" has a 35 lb compression rating or ILD.Uses: Ideal for oval and round poker tables, furniture cushions, boat cushions, car cushions, foam mattresses, bedding support, and various home and commercial upholstery applications.Important: Do not use a box cutter to open the package. Use a ballpoint pen or pencil to make a small incision, then carefully tear it open.When unpacking, allow at least 3 days for the foam to expand and regain its original size and shape.
