Sponge products are widely used in furniture filling due to their softness, flexibility, and durability. They provide excellent cushioning and support in sofas, chairs, and mattresses, enhancing comfort for daily use. High-quality sponge materials can retain their shape over time, resist deformation, and improve the lifespan of furniture. In addition, they offer good breathability, helping to regulate temperature and reduce moisture buildup. Sponge fillings also absorb shock and reduce pressure on the body, making them ideal for ergonomic designs. Overall, sponge products play a key role in creating comfortable, supportive, and long-lasting furniture for modern living spaces.
