Frequently Asked Questions about Sponge?
a. Why does the sponge turn yellow?
①Due to the fact that the heat released by the self-reaction cannot be released quickly during the foaming/processing process, the burning core turns yellow. ② Oxidation and yellowing due to ultraviolet radiation.
b. The mattress will smell when you just open it
The sponge is a polyurethane product, and all new sponges will smell a little like a new car, especially when you open the compression bag, but this smell is almost harmless to the human body. Newly purchased mattresses are recommended to be ventilated for 48 hours before use.
c. Will the foam mattress collapse?
It depends on the quality of the mattress. A good quality sponge mattress has good foaming, uniform size, strong durability and good resilience, so it is not easy to collapse.
What Is The Common Memory Foam Mattress?
The scientific name of memory foam is slow rebound sponge, which is a kind of flexible polyurethane foam. It was developed by NASA's Ames Research Center in 1966 to reduce the enormous pressure on astronauts' bodies when they leave the ground. The sponge contains open-structured molecules that can move under external force, dispersing the force to conform to the entire contact surface.
Advantages: ①Memory foam can disperse the pressure received by the human body, create a sense of "zero pressure", reduce the discomfort caused by the human body due to contact and extrusion with the mattress, and promote the blood circulation of the human body. ②Enhance the comfort of people's sleep and promote deep sleep.
Memory foam is divided into warm memory foam and non-warm memory foam.
Warm memory foam is the mainstream memory foam on the market at present. Because its softness and hardness will change significantly with temperature, it is called warm memory foam in the market. Change with temperature is his characteristic and disadvantage. For example, when the temperature is lower than about 10 degrees, the memory foam will become hard, especially when it is below 0 degrees, it will be as hard as a stone. Therefore, in a room with low temperature in winter, the use of traditional memory foam needs to absorb heat or become soft and comfortable after a period of use. Common temperature memory foam mattress brands are: Tempur, Blue Box, Xilinmen, etc.
Non-warm-sensing memory foam is also called Qi-sensing foam, which is researched and transformed according to the characteristics and disadvantages of memory foam's warmth-sensing. As the name suggests, the softness and hardness of the non-warm memory foam will not vary significantly with temperature changes, allowing people to experience the comfort of memory foam in any environment. Qi sense cotton uses more environmentally friendly mdi as the main raw material, making the product more green and environmentally friendly. Due to the special cell structure, it feels softer and more comfortable, and has a strong moisture absorption function, which can preserve the cool feeling of the sponge surface. Common non-thermal memory foam mattress brands are: Dream Lily, etc.
For use as a pillow or mattress, of course, non-warm memory foam is better than warm memory foam.
