High-density foam features a compression rate of 44 lbs, providing the perfect balance of cushioning and stiffness. This soft yet firm foam supports an individual's weight without excessive compression. 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 on, one should 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 allowing it to return 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 bounce back to its full 4-inch thickness has a 33 lb. compression rating or ILD. It's important to note that all foam sheets are sold per sheet, not per yard. When opening the package, it's recommended to use a ball-point pen or pencil rather than a box cutter to avoid damaging the foam.

Medium-density foam is a versatile option, providing firmness and relaxation in cushions. Its high-quality compression and materials ensure long-lasting durability, even under heavy use.

Foamrush's foam is certified for quality, with a density of 1.8 and a compression rating of 44 ILD. This high-density, firm foam is designed for heavy traffic and high-use applications, with a lifespan of approximately 7-12 years. All Foamrush foam is Certipur-US certified, ensuring it is safe and environmentally friendly.

Foamrush offers cut-to-order foam products, allowing customers to customize the size and shape to meet their specific needs. The foam can be easily sliced with a sharp knife, serrated knife, electric knife, or electric hot wire foam cutter. It can also be glued together to create wider pieces or layered to increase thickness.

Foam can be used for a variety of projects beyond just sofas and chairs. It can be used to repair worn-down chairs, create custom cushions for patio furniture, ottomans, stools, headboards, RVs, boat seats, car seats, golf cart seats, workout benches, cots, window seats, and restore vintage furniture. It can also be used to make foam mattress toppers and carrying cases for delicate glass or ceramic items, as well as accent pillows and various other crafts and DIY projects.

When receiving the foam, it's essential to open the package immediately and allow the foam to expand to its original size, which can take up to 3-4 days. Caution should be exercised when opening the package, and sharp tools should be avoided to prevent damaging the foam.
