What is a sponge mattress?

The current foam mattresses are mostly slow rebound foam mattresses. Slow rebound foam mattresses have good rebound characteristics, which greatly reduces the necessity of turning over in bed, thereby improving people's sleep quality. The difference between slow rebound memory foam and traditional sponges is: slow rebound memory foam is a special material that is different from any sponge that has been touched before. Slow rebound memory foam is a material that can deform according to changes in body temperature. When the slow rebound sea surface is pressed, it will not produce a rebound force until all the pressure is evenly distributed. When the external force stops squeezing, it will slowly return to its original shape.
