High Density Foam RV Mattress Replacement with Cotton Cover, Medium Firm, Made in USA, CertiPUR-US Certified

With a compression rate of 44lbs, high density foam offers the perfect balance of cushioning and stiffness. Despite being soft, it maintains firmness and support, allowing an individual to sit without excessive compression. Firmness is determined by compression, not density. To avoid overly firm cushions or sinking mattresses, pay attention to the compression or ild number. This number indicates the pounds required to compress a piece of foam by 25% while retaining the original thickness. For instance, a 4" foam piece needing 33 lbs. to compress by 1" and return to 4" has a 33 lb. ild rating. To open the foam, avoid using a box cutter and opt for a ballpoint pen or pencil for durability. High density foam, ideal for mattresses and cushions, offers a firm yet comfortable touch. Its premium compression and materials ensure longevity, even under heavy pressure, lasting 7 to 10 years. It's crucial to order the correct size by knowing the mattress dimensions in advance, including height. Consider combining the height of the bed frame, foundation, or adjustable base with the mattress for an accurate sleep system height measurement. Note that the cover is not included, and a 50% restocking fee may apply for returns.
