High-density foam has a compression rate of 44 lbs. It offers the perfect balance of cushioning and firmness. Its softness is complemented by its ability to maintain its firmness and support, ensuring a comfortable sitting experience without excessive compression. The level of compression, rather than density, determines the firmness of the foam. To avoid a cushion that is as hard as a rock or a mattress that sinks when you sit on it, you need 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% and have it bounce back to its original thickness. For instance, a 4-inch thick foam piece that requires 33 lbs to be compressed by 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 recommended to use a ball-point pen or a pencil to open the packaging, rather than a box cutter, to avoid damaging the foam. Start by making a small incision and then break the packaging from there.

Medium-density foam is used for a firm yet comfortable cushion. It has high-quality compression and materials, ensuring its longevity even when subjected to heavy weight.

Foamrush's foam is certified for the highest quality. It has a density of 1.8, a compression of 44 ILD, and a 100% recovery rate, making it ideal for revitalizing worn-out chairs, sofas, cushions, and other high-density replacement foam. The foam 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, and it is expected to last from 7 to 12 years.

Foamrush's foam is CertiPUR-US certified, ensuring quality assurance. All of the company's foam products are safe and meet regulatory standards, unlike non-certified or non-regulated foams.

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

Foamrush's foam is easy to work with using various slicing devices. You can trim the edges or stack layers to achieve the desired thickness and customize the foam to meet your needs. The foam can also be glued together to create wider pieces or layered to make thicker cushions.

When receiving the foam, it is important to open the package immediately. Caution should be exercised, and sharp tools should be avoided to prevent cutting or tearing the foam. After removing the foam from the shipping box, it should be unrolled to allow it to relax.
