The current foam mattresses are mostly slow rebound foam mattresses. Slow-rebound foam mattresses have good resilience characteristics, which greatly reduces the necessity of tossing and turning in the bed, thereby improving people's sleep quality. The difference between a slow-rebound memory foam and a traditional sponge is that the slow-rebound memory foam is a special material that is different from any sponge that has been in contact before, and reduce the price of a queen size mattress. Slow-rebound memory foam is a material that can deform according to changes in body temperature. When the slow rebound sea surface is pressurized, it will not produce a rebound force until all the pressure is evenly dispersed. When the external force stops, it will slowly return to its original shape.
How to distinguish adulterated sponge from pure sponge:
1. Look: The process of sponge is mainly divided into two categories: foaming and PU. The doping causes the fake sponge to foam unevenly and has large holes. The pores of pure sponge are small and even;
2. Touch: pure sponge feels smooth and delicate, doping makes the fake sponge feel rough and extremely elastic;
3. Extrusion: seemingly the same thickness and hardness of sponge, doping makes the fake sponge prone to sag once squeezed, and it will not spring for a long time; pure sponge has strong support strength and it is difficult to deform after long-term extrusion;
4. Price: Doping makes the fake sponge greatly reduce the cost due to the addition of stone powder, and the price is low; the polyurethane material used for pure sponge is more expensive than the adulterated sponge;
5. Lifetime: adulterated sponges are prone to slipping due to the addition of stone powder, which is prone to slipping; pure sponges are durable;
6. Tensile strength comparison between adulterated sponges and pure sponges: the longer the sponges with the same appearance, the better the tensile strength;
7. Comparison of breaking strength of adulterated sponge and pure sponge: sponge with the same appearance, pure sponge can bear strong load.
The advantages of the foam mattress are: the temperature-sensing characteristics of the foam mattress. When the foam mattress feels the body temperature of the human body, the particles on the surface of the foam soften, and the gradually softened particles distribute the pressure area evenly, thereby eliminating the pressure points and making the body blood will not be compressed; the foam mattress also has the characteristics of cushioning and decompression, good breathability, antibacterial and anti-mite, soft and light, and good resilience; the biggest feature of the foam mattress is that it can absorb the weight of the human body, and the person lies It feels like it is floating in the air; the foam mattress follows the shape of the person. By letting the spine and joints rest in their natural physiological state, they provide complete support for the body, head, neck, and waist, thus releasing the pressure and making people feel a weightlessness sense.
