High-density foam features a compression rate of 44 lbs, offering the perfect balance of cushioning and stiffness. Its soft yet firm texture provides excellent support, allowing individuals to sit on it without excessive compression. Compression, not density, is the key determinant of firmness. To avoid a cushion as hard as a rock or a mattress that sinks when sat upon, it is crucial to check the compression or ILD (Indentation Load Deflection) number. Compression refers to the number of pounds required to compress a piece of foam by 25% while still maintaining its ability to bounce back to its original thickness.

For example, a 4-inch thick piece of foam that requires 33 lbs to compress it by 1 inch and 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 they should be opened using a ballpoint pen or pencil, starting with a small incision and then breaking it from there.

Medium-density foam is commonly used for firmness and a relaxable cushion. It possesses high-quality compression and materials, enabling it to withstand harsh weight application for extended periods. A 50% restocking fee may apply on returned items.

Foamrush's foam is certified for the highest quality, featuring a density of 1.8, a compression of 44 ILD, and a 100% recovery rate 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 quality assurance and safety compared to non-certified or non-regulated foam. Customers can use this foam for various projects in their homes, including repairing worn-down chairs, creating custom cushions for patio furniture, ottomans, headboards, RVs, boat seats, car seats, and more.

The foam is easy to customize using tools such as slicing devices. Customers can trim the edges, stack layers for increased thickness, or glue pieces together to create wider or thicker cushions. Foamrush recommends opening the package immediately and using caution to avoid cutting or tearing the foam during the process.
