High-density foam has a compression rate of 44 lbs. It features the perfect balance of cushioning and stiffness, offering a soft yet firm support that prevents excessive compression when an individual sits on it. Compression, not density, is the key factor determining the firmness of the foam. If you don't want 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 still have it bounce back to its original thickness. For instance, 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.

It's important to note that all foam sheets are sold per sheet, not per yard. When cutting the foam, it's recommended to use a ball-point pen or a pencil instead of a box cutter to start a small incision and then break it from there. This method helps maintain the durability of the foam, which can last for 7 to 10 years.

Medium-density foam is often used for firm yet relaxable cushions. It has high-quality compression and materials that help it withstand heavy weight for extended periods, ensuring its longevity. This type of foam can be customized for a variety of applications, such as oval and round poker tables, furniture cushions, boat cushions, car cushions, foam mattresses, and bedding support.

Foamrush's foam is easy to customize, as it can be sliced through with various tools, including a sharp knife, serrated knife, electric knife, or electric hot wire foam cutter. You can trim the edges or stack layers to achieve the desired thickness, and the foam can also be glued together to create wider pieces or layered to form thicker cushions. This versatility allows you to customize the foam to perfectly meet your specific needs.

Foam can be used for much more than 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, and restore vintage furniture. Additionally, foam can be used as mattress toppers, carrying cases for delicate glass or ceramic items, packing foam, accent pillows, and a wide range of other crafts and DIY projects.
