High-density foam offers a compression rate of 44 lbs, providing the perfect balance of cushioning and stiffness. It is soft yet maintains its firmness and support, ensuring a comfortable sitting experience without excessive compression. The compression, or the number of pounds required to compress the foam by 25% and return to its original thickness, is what determines the firmness, not the density. To avoid a cushion that is as hard as a rock or a mattress that sinks when you sit on it, it's crucial to check the compression or ILD (Indentation Load Deflection) number. 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.

When purchasing foam, it's important to note that all foam sheets are sold per sheet, not per yard. To open the packaging, it's recommended to use a ball-point pen or a pencil instead of a box cutter, as this can help prevent any unintentional cuts or tears. Start by making a small incision and then break the foam from there.

High-density foam is designed for durability and longevity, with a lifespan of 7 to 10 years. Its high-quality compression and material ensure that it can withstand heavy weight without compromising its performance. Foamrush's foam is certified for suitability, with a density of 1.8 and a compression of 44 ILD, ensuring recovery and durability. This foam is perfect for revitalizing worn-out chairs, sofas, cushions, and other high-density replacement applications, providing the balance of support, comfort, and longevity.

Foamrush's foam is Certipur-US certified, ensuring quality assurance and safety compared to non-certified or non-regulated foam. The versatility of foam extends beyond just sofas and chairs; it can be customized for a variety of projects, such as repairing worn-down chairs, creating custom cushions for patio furniture, ottomans, headboards, RVs, boat seats, car seats, workout benches, and more. It can also be used for packing and cushioning delicate items.

Customizing the foam is easy, as it can be trimmed, stacked, or glued together to meet specific size or shape requirements. Foamrush recommends opening the package immediately and using caution when cutting the shipping box to avoid damaging the foam. Once the foam is removed, it should be unrolled to allow it to relax and regain its original form.
