High-density foam has a compression rate of 44 lbs, featuring the perfect balance of cushioning and stiffness. It is soft yet maintains its firmness and support, preventing excessive compression when an individual sits on it. Compression, not density, determines the firmness of the foam. To avoid a cushion that is as hard as a rock or a mattress that sinks when sat upon, one must check the compression or indentation load deflection (ILD) number, which represents the number of pounds required to compress a piece of foam by 25% and still have it bounce back to its original thickness.

For example, a 4-inch thick piece of foam that requires 33 lbs to be compressed by 1 inch and then return to its full 4-inch thickness has a 33 lb compression rating or ILD. It is important to note that all foam sheets are sold per sheet, not per yard, and it is recommended to use a ball-point pen or pencil to open the package, rather than a box cutter, to avoid damaging the foam.

Medium-density foam is often used for firmness and relaxation, as it has high-quality compression and materials that allow it to last for extended periods, even under heavy weight application. The foam offered by Foamrush is certified for the highest quality, with a density of 1.8, a compression of 44 ILD, and a 100% recovery rate durability. This foam is excellent for reviving worn-out chairs, sofas, cushions, and other high-density replacement foam applications.

Foamrush's foam is uniquely formulated to provide the perfect balance of support, comfort, and durability. The high-density firm foam is designed for heavy traffic and high-use applications, with a lifespan of 7-12 years. All Foamrush foam is CertiPUR-US certified, ensuring that it is safe, non-toxic, and better for the health and environment compared to non-certified or non-regulated foam. The foam is proudly made locally and cut-to-order to ensure the best quality for customers.

Foamrush's foam is easy to customize, as it can be sliced through with various tools, such as a sharp knife, serrated knife, electric knife, or electric hot wire foam cutter. Customers can trim the edges or stack layers for extra thickness to meet their specific needs. The foam can also be glued together to create wider pieces or layered to form thicker cushions. Foamrush foam can be cut and customized to any desired size or shape.

When receiving the foam, it is essential to open the package immediately and remove the foam from the box to allow it to relax and fully expand to its original size, which may take 3-4 days. Caution should be exercised, and a box cutter should not be used to open the package, as it may cut through and damage the foam. Following these product care instructions will ensure the best results and the longevity of the foam.
