◆ The special 7-layer structure firmly catches body pressure The difference is clear! If you place a 3kg dumbbell on a futon and compare how much it sinks, the difference is obvious! With an ordinary mattress, the dumbbell looks as if it is about to touch the floor, but with this product, you can see that the hard cotton in the center and the rolled cotton around it are firmly supporting the weight. Three types of padding with different functions are effectively arranged The center of the mattress is filled with hard batting to prevent the feeling of touching the floor, and around it is a multi-layered structure made of elastic wool with excellent moisture absorption and release properties, and high-performance polyester ``Mighty Top(R) II'' that has been treated with anti-mite, antibacterial and deodorizing properties. In addition, a sandwich manufacturing method is used in which the materials are arranged alternately to ensure that the functions of each material can be fully utilized. High-performance materials and meticulous manufacturing techniques ensure an ideal sleeping experience.
