Did you know the early mattresses in human history? They were made of grass and leaves by the ancients. They have a history of more than 70,000 years. It was discovered by archaeologists in a cave site in South Africa in 2011. At that time, such things as sleeping were quite crude. In the long history, human beings have never stopped demanding to improve sleep quality. People used to make mattresses from several materials. Sheepskins, sawdust, leaves, hay, feathers, linen, cotton etc. 1865, the first spring mattresses came out. Nowadays, high technology developed a lot. Mattresses have undergone earth-shaking changes in both fabric and material.

Mattress is a necessity in life. It directly affects our sleep and quality of life. Buying mattresses varies from person to person. Everyone's sleep experience is different. No matter how good the mattress quality is, if it is not suitable for us, it will still affect our sleep. So, it is important for us to choose a suitable mattress.

We will compare it with ordinary sponge. The biggest characteristic of memory cotton is slow deformation. You can feel the experience of sinking slowly when you lie down. You can imagine the feeling of mud. When you lie down, the mud will form a depression suitable for your body shape. Of course, the mud will not recover automatically. But memory cotton can. Memory cotton still has its limit. General mattresses use memory cotton of 2-5 cm or so. The memory cotton layer is too thick and the depression is too large. It will make it uncomfortable. Just like you can't sink too deep in the mud.

Therefore, we need to look at several parameters when selecting memory cotton mattresses.

One is thickness.

It is possible to have a thickness of 2-5 cm. It can bring the feeling of "zero pressure". However, some ordinary merchants claim that their products are thicker or full memory cotton. You should be cautious. It is possible to use density stratification for full memory cotton. Yet only big brands with high prices can do it.

The Density of Memory Cotton.

Memory cotton has a wide range of uses. The density suitable for mattresses and pillows should be around 70D-80D. Rebound speed of 3-5 seconds is preferred. If the rebound is too slow, it will be stiff and uncomfortable. If you rebound too fast, it is not much different from sponge.

Is it better to choose temperature-sensitive memory cotton or non-temperature-sensitive memory cotton? It is best to choose non-temperature memory cotton.

One must choose a credible brand manufacturer to buy memory cotton. Nowadays, there are a lot of merchandise selling packages and feelings. When we buy products, we cannot just start from the appearance. If there is no understanding of the product itself, it will do us all harm but no good.

You should know whether you are suitable for memory cotton. Many people may have tried the memory cotton mattress in the hotel. If you feel good, you can consider buying it. However, maybe your lumbar spine is not good at ordinary times and you don't like soft beds. You still don't recommend buying memory cotton mattresses.
