High-density foam has a compression rate of 44 lbs, featuring the perfect amount of cushioning and stiffness. Its soft yet firm texture provides support without excessive compression, making it an ideal choice for seating. Compression, not density, determines the firmness of the foam. To avoid a cushion that is too hard or a mattress that sinks, it is crucial to check the compression or indentation load deflection (ILD) number. Compression refers to the number of pounds required to compress a piece of foam by 25% while maintaining its ability to bounce back to the original thickness.

For example, 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. Importantly, all foam sheets are sold per sheet, not per yard. When unpacking, it is recommended to use a ball-point pen or pencil to make a small incision and then break the foam, rather than using a box cutter.

Medium-density foam is used for a firmer yet relaxable cushion. This type of foam has high-quality compression and materials, ensuring longer-lasting durability even under heavy weight. However, a 50% restocking fee may apply on returned items.

The foam is easy to customize using various tools such as a sharp knife, serrated knife, electric knife, or electric hot wire foam cutter. Customers can trim the edges or stack layers to adjust the thickness to meet their specific needs. The foam can also be glued together to create wider pieces or layered to form thicker cushions.

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 furniture, ottomans, stools, headboards, RVs, boat seats, car seats, golf cart seats, workout benches, cots, window seats, and more. Foam can also be used to restore vintage furniture, create foam mattress toppers, and serve as packing material for delicate glass or ceramic items.

Additionally, this density of foam can provide entry-level sound blocking when used to cover windows in a room. Charcoal Firm foam, being denser, is particularly well-suited for packing and protecting sensitive objects such as cameras and glasses, as it is more resistant to damage.
