The mattress is the soul of the entire bed. A mattress, placed directly on the floor and supported by a bedstead, was almost indistinguishable from the sense of lying down. Of course, there are more criteria for selecting mattresses. In this article, I will clarify some of the “majority†of choosing mattresses. As long as there is an sensible purchase to avoid the complications of commercial propaganda, a good night’s sleep is not expensive.
A good mattress should be ergonomic and take care of people's behavior during sleep. In principle, a good mattress should ensure that the human body can maintain its level to the greatest extent possible regardless of its prone position, and evenly distribute gravity to prevent gravity from accumulating at individual sites. Once the level of the human body changes, the force of the human body that receives the force of gravity gathers in the area that is at a lower depression, causing them to bear additional pressure and causing discomfort.
At the same time, the surface of a good mattress that is in contact with the human body should have a certain degree of flexibility, so that the contact area between the mattress and the human body is increased, and the pressure of the contact portion between the human body and the mattress is effectively reduced through the relatively scattered support. If the mattress is stiff, the area where the human body contacts the mattress is concentrated on several prominent points, making these points overwhelmed.
The significance of turning over
Here, we must talk about the law of human sleep and the effect of "turning over" on sleep. At present, the more accepted theory is that sleep related to human body rest and repair can be divided into several stages that are shallow and deep. After normal adults fall asleep, they need to experience 4-6 times of shallowness in about 8 hours of sleep time. Into the deep and then shallow depth cycle. Among them, deep sleep has stronger functions of relaxing and repairing the human body. In this respect, light sleep is much less efficient. If the bed becomes uncomfortable, it will cause difficulty in falling asleep and increase the number of turns. On the one hand, the person's sober time on the bed is too long and the limited sleep time is lost. On the other hand, the proportion of the entire sleep process flowing to shallow sleep is too high, and effective deep sleep is insufficient.
Turning over can help prevent hidden health problems caused by the long-term accumulation of internal organs, help the body fluids to circulate smoothly, and prevent snoring. Turning over is a way of self-adjustment by the human body. It is unavoidable and beneficial to turn over a moderate number of times during sleep. It can be said that even a bedding that can provide idealized support cannot substitute for the positive effect of turning over on the internal organs of the human body. As long as people are in the gravity environment of the earth, turning over in sleep is a must.
As for the appropriate standards for turning over, it depends on the individual's body size, weight, and other factors. However, a relatively simple measure is that natural turning is often unconscious and occurs during sleep. It is usually not normal to consciously turn up when you are awake. In other words, under normal circumstances, when you wake up, you should not feel that you have deliberately turned over, and you should not leave the impression of turning upside down. Of course, frequent adjustments of posture and turning over due to feeling uncomfortable may be caused by bed problems, but it may also be due to problems such as musculoskeletal disorders and weight. For such cases, it is not consumer-grade. The mattress can be solved.
The standard of a good mattress The variety of materials and workmanship on the market is dazzling. In fact, as long as the following points are met, it is basically a good mattress that can meet our needs. Before we embark on the detailed selection of various types of mattresses, let's review the basic qualities that a good mattress should have.
structure
As mentioned above, a good mattress should have enough supporting structure to provide strong support for the human body, and should have a soft contact structure to evenly distribute the pressure. In simple terms, it should be "soft and soft."
Materials
At present, there are a wide variety of main materials for mattresses. Before elaborating on the selection of various types of mattresses, we only list the common qualities that a good mattress should have. That is health, environmental protection, and very little volatile matter. Strong and durable, it can maintain a stable state for a long time.
work
We can't just make the right choice through the appearance of a mattress, but watching the appearance of a mattress allows us to eliminate the worst product, because a fine-looking mattress may not be good, but A mattress that looks rough is a little bad. How can manufacturers who are tolerant of their products sell poorly be responsible for their internal quality? In addition to checking whether the mechanics are fine, whether the seams are accurate, and whether the bead is compact, some mattresses provide “window†and zipper design for people to inspect their interior, although it is difficult for us to distinguish the intrinsic quality through this eye observation. Bad, but it can be seen whether the work is careful and meticulous. In addition, a good mattress should have an overall texture that looks reassuring. This texture is a reflection of well-designed and mature production processes. Given so many choices in the market, if a mattress just seems to be almost what it feels like, it is better to give it up.
