High-density foam boasts a remarkable compression rate of 44 lbs. It offers the perfect balance of cushioning and stiffness, with a soft yet firm feel that provides ample support for sitting without excessive compression. Compression, not density, is the key factor that determines the firmness of foam. To avoid a cushion as hard as a rock or a mattress that sinks when you sit on it, you must consider the compression or ILD (indentation load deflection) number. Compression refers to the number of pounds required to compress a piece of foam by 25% and have it bounce back to its original thickness. For instance, a 4-inch-thick foam piece that needs 33 lbs to be compressed by 1 inch and return to its full 4-inch height has a 33 lb compression rating or ILD.

It's important to note that foam sheets are sold per sheet, not per yard. When unpacking, refrain from using a box cutter, as it may damage the foam. Instead, use a ballpoint pen or a pencil to make a small incision and then break the foam from there. With proper care, high-density foam can last an impressive 7 to 10 years.

Medium-density foam, on the other hand, strikes a balance between firmness and relaxation, featuring high-quality compression and materials that ensure longevity even under heavy loads. However, be aware that a 50% restocking fee may apply on returned items.

Foamrush's foam is certified for the highest quality, with a density of 1.8, a compression of 44 ILD, and a 100% recovery rate. This versatile foam is perfect for reviving worn-out chairs, sofas, cushions, and other high-density replacement applications. The unique formulation provides the ideal balance of support, comfort, and durability. High-density firm foam is designed for heavy-traffic and high-use scenarios, with a lifespan of 7 to 12 years.

Foamrush's foam is Certipur-US certified, ensuring quality assurance and safety compared to non-certified or non-regulated options. This makes our foam suitable for a variety of home projects, beyond just sofas and chairs. Customers can customize the foam to repair worn-down chairs, create custom cushions for patio furniture, ottomans, stools, headboards, RVs, boats, cars, workout equipment, and more. The foam can also be used for packing delicate items or crafting accent pillows and other DIY projects.

Customizing the foam is a breeze, as it can be easily cut and shaped using common tools. Edges can be trimmed, and layers can be stacked for additional thickness to suit your specific needs. The foam can also be glued together to create wider pieces or layered to form thicker cushions.

When unpacking your Foamrush foam, be sure to remove it from the shipping box immediately and unfold it to allow the material to relax. Avoid using sharp tools to open the package, as they may damage the foam.
