High-density foam has a compression rate of 44 lbs, featuring the perfect amount of cushioning and stiffness. It is soft yet still holds its firmness and support, allowing an individual to sit on it without compressing the foam too much. Compression, not density, determines the firmness. To avoid a cushion that is hard as a rock or a mattress that sinks when sat on, one must check the compression or ILD (indentation load deflection) number. Compression refers to the number of pounds necessary to compress a piece of foam 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 pack it down 1 inch and return to its full 4-inch thickness has a 33 lb. compression rating or ILD.

All foam sheets are sold per sheet, not per yard. It is important to use a ball-point pen or a pencil to open the package, as a box cutter should not be used to avoid damaging the foam.

Medium-density foam is used for firmness yet relaxable cushions. It has high-quality compression and material to keep it lasting for longer periods, even when harsh weight is applied.

Foamrush's foam is certified for the highest quality, with a density of 1.8, compression of 44 ILD, and a 100% recovery rate durability. This foam is great for revitalizing worn-out chairs, sofas, cushions, and other high-density replacement foam. It is uniquely formulated to provide the perfect balance of support, comfort, and durability.

High-density firm foam is designed for heavy traffic and high-use applications, with a lifespan of 7-12 years. Foamrush's foam is Certipur-US certified, ensuring it is safe, non-toxic, and better for health and the environment compared to non-certified or non-regulated foam. The company proudly manufactures its foam locally.

Foamrush's foam is easy to customize, as it can be sliced through with tools such as a sharp knife, serrated knife, electric knife, or electric hot wire foam cutter. Edges can be trimmed, and layers can be stacked for extra thickness to meet specific needs. The foam can also be glued together to create wider pieces or layered upon one another to create thicker cushions.

When receiving the foam, it is essential to open the package immediately and use caution not to use a box cutter or anything sharp, as it may cut through and tear the foam. The foam should be removed from the box and unrolled to allow it to relax and fully expand to its original size, which may take 3 to 4 days. It is recommended not to cut the foam until these product care instructions have been followed.
