High-density foam has a compression rate of 44 lbs, featuring the perfect balance of cushioning and stiffness. It is soft yet maintains its firmness and support, allowing individuals to sit on it without compressing the foam too much. Compression, not density, determines the firmness. To avoid a cushion that is as hard as a rock or a mattress that sinks when sat on, it is essential 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 still have it bounce back to its original thickness. For instance, a 4-inch thick piece of foam that necessitates 33 lbs to compress it 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. They should be opened with a ball-point pen or pencil, starting with a small incision and then breaking it from there, rather than using a box cutter.

Medium-density foam is used for a firm yet relaxable cushion. It has high-quality compression and material to ensure its longevity, even when subjected to harsh weight. A 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 durability. This foam is ideal for revitalizing worn-out chairs, sofas, cushions, and other high-density replacement foam applications. It is uniquely formulated to provide the perfect balance of support, comfort, and durability.

The 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 their foam is certified as being safe, unlike non-certified or non-regulated foam.

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

Foamrush's foam is easy to work with using tools such as most slicing devices. Customers can trim the edges or stack layers for extra thickness to customize the foam to their needs. The foam can also be glued together to create wider pieces or layered upon one another to create thicker cushions.

It is important to open the foam package immediately and use caution when doing so, avoiding the use of sharp objects to prevent cutting or tearing the foam.
