High-density foam is a type of foam material known for its durability and support. It is made from polyurethane and has a higher density than standard foam, which means it can withstand more weight and pressure. This makes it ideal for use in products like mattresses, cushions, and furniture, where comfort and longevity are important. Due to its firmness, high-density foam is often used in memory foam mattresses and ergonomic chairs. It provides excellent support for the body, helping to maintain proper alignment while sitting or sleeping. Additionally, it is resistant to wear and tear, making it a popular choice for both residential and commercial applications.
