A person spends most of his life in a dream. The oldest mattress found is more than 77 thousand years old.
It should be noted that the mattress can also perform some related functions - to fight pressure sores, reduce the load on the spine and improve blood circulation.
There are quite a few samples of these products on the market today. Together with doctors and orthopedists, it is worth considering the main misconceptions about mattresses.
There are simple mattresses and orthopedic ones. This is purely a marketing gimmick. There are no criteria for mattresses, any prescribed norms or GOSTs that would allow this product to be considered orthopedic. For a mattress to become such, you just need to choose the right one, taking into account the weight of the person, his age and individual physiological characteristics. Only on the basis of these factors, as well as the daily activity of a person, we can say what properties the mattress should have. Do you need a rigid correction of the spine, or does intervertebral hernia, on the contrary, require softness and anatomicality of the bed? The individuality of each person will help you choose the mattress that will further fulfill orthopedic purposes. After all, if a person weighing 140 kilograms is put on an "orthopedic" mattress with a recommended load of 120 kilograms, then what kind of healing properties can we talk about?
It is healthier to sleep on hard mattresses. This statement is similar to the previous one. In fact, everything is individual here. Hard mattresses are well suited for young children. At this time, the spine grows and forms. So hard mattresses will be useful as an important prevention of diseases of the musculoskeletal system. But for an adult with soft tissue flow, a hard surface will be harmful. After all, the pressure from the mattress will only contribute to low blood circulation, and not prevent it.
The mattress must be selected taking into account the person's age. But this is the sheer truth. The fact is that children and adolescents are better off not sleeping on elastic and hard surfaces. For those who are well over 40, it is better to choose an option with an anatomical structure. Middle-aged people can be guided by their own taste.
A quality mattress should be made only from natural materials. There are quite a few springless mattresses that are made from artificial heat-sensitive fibers. Modern mattresses use a special foam that can shape the body and react to its temperature. They have pretty good anatomical properties. It is simply impossible to find analogues of such materials in nature.
Bonnel springs (dependent block) are obsolete. This is actually the truth. The block with dependent springs has a very low orthopedic effect. Indeed, interacting with each other, the springs under the lying person form a very real pit. For the spine, the effect of a hammock and a wave appears, a person feels all vibrations. This is the difference between mattresses with Bonnelli springs. They have a low price, but there is no need to talk about any kind of orthopedic support. An alternative is the PocketSpring independent spring block, where each spring moves independently.
Obese people require special mattresses. And this is really so, because those who weigh a lot need to pick up non-bending products. The mattress should be as elastic and rigid as possible, the number of springs in it should be at least two hundred per square meter. However, there are other factors to consider. In addition to rigidity, an anatomical surface is also required from the product. This is important if a person suffers from limb flow. It is also desirable that the springs are made of hardened steel. They have the effect of memory, when pressed, trying to return to their original position.
Soft mattresses are more comfortable. It is difficult to talk about comfort, because it is a subjective concept, individual for each person. In this case, attention must also be paid to weight, body complexion. Some people are generally comfortable sleeping on the floor. And hardness and softness are relative concepts. It is still correct to talk about elasticity. The mattress should support the body and prevent depressions in the shoulder and hip area from forming. And the main thing here is not to overdo it. For those who are hard on the main mattress, it is advisable to put an additional super-thin one on the main mattress. It will be both useful and comfortable.
For partners with different weights, you need to purchase a combined mattress. The difference in weight of 30 kilograms can already be considered critical. In this case, it is best to put two different mattresses on the bed. However, there is another option - a single mattress, but with different hardness zones. With this design, each person will sleep in their own area, so the mattress will not resonate and will not allow a person with a small weight to roll to their heavier partner.
The properties of a spring mattress depend on its filling. And this is true, because in a good mattress there are several fillers at once, each of which has its own task. Latex will give elasticity, coconut coir - rigidity, sheep wool - warmth, cotton fibers will maintain an ideal microclimate, and linen and jute felt will increase the service life. The convenience of this or that model depends on the layers, their quality and thickness.
Springs cannot be completely independent. This problem applies not only to blocks of independent springs, but also to volume-elastic materials - latex, viscoelastic or polyurethane foam. After all, the elastic walls of the air bubbles that make up these materials prevent them from behaving like little springs. But in both a spring and a springless mattress, it is impossible, in principle, to compress only one spring or bubble so that the neighboring ones do not deform. That is why it is possible to increase the elasticity of the block either by using a large number of springs (more than 250 per square meter) or to ensure their independence by connecting the spring covers only in the middle.
In principle, a spring mattress cannot be comfortable, since the springs exert pressure and disrupt blood circulation. The laws of physics say that any support puts pressure. If a person is lying on a mattress, then it is important for him that the pressure does not interfere with the natural physiological processes that take place in the body. It is logical to assume that the more accurately the mattress is able to repeat the shape of the body, the more the body weight will be distributed over the surface. Studies have shown that if a spring mattress contains more than 250 springs per square meter, and the comfort layer is 2-3 centimeters, then this completely solves the problem with an orthopedic support. The mattress itself will be well ventilated.
The more springs in the mattress, the better. As mentioned, more springs actually help the mattress to better fit the human anatomy. However, this property is smoothed out by layers of comfort that transfer pressure to multiple springs at once. Studies have shown that a layer 3-4 centimeters thick makes an increase in the number of springs over 300 per square meter simply meaningless - there will be no additional effect. On a rack and pinion base, many springs may be deprived of support, because some fall into the gap between the rails. And the smaller the springs, the more they will disappear. Over time, they will create bubbles on the underside of the mattress and a wave on the top. To make this process invisible, many manufacturers recommend turning the mattress over at least once every 3 months.
Latex, like any organic material, has a limited lifespan. The natural material is the sap of the Hevea tree, which is converted into a polymer in the air. Foamed latex in its pure form is never used, since, like all organics, it is subject to decay. But if you add preservatives and stabilizing additives to the material, this will give it durability and safety. As a result, latex can last for many years.
Latex-based mattresses have a specific smell. The fact that inexpensive latex varieties have an unpleasant odor is explained by the presence of special compounds, oligomers, in them. They form when latex is poorly polymerized when the process is accelerated by abnormally high temperatures. This happens in semi-clandestine production in East Asia, where the climate is hot. Under normal conditions, polymerization at a temperature of 5-8 degrees lasts 30-40 hours. Then oligomers are not formed, and the latex is odorless. Elite varieties of this material are generally created at subzero temperatures, which guarantees the absence of unpleasant sensations.
A mattress with natural fillings is an ideal breeding ground for dust mites and bacteria. In fact, dust mites, not bacteria, are the main inhabitants of the beds. Their size is tenths of a millimeter, and these creatures feed not at all on the natural materials of the mattress, but on the scales of human skin. It is known that the waste products of these mites are strong allergens. That is why an environment should be created inside the mattress that would make the life of ticks unbearable. But how to chemically kill them without harm to human health? An effective way is to create unbearable conditions for ticks - they need heat and humidity of at least 70%. A person will give warmth in any case, but humidity can be reduced due to effective ventilation. It makes sense that innerspring mattresses will ventilate much better than foam cores. As a result, it is much more attractive to dust mites.
Jacquard fabric is best for mattress covers. Outwardly, this fabric really looks more representative. But the internal structure of the knit weaving makes this particular material more suitable for making mattress covers. The knitwear also stretches better, which allows you to repeat the curves of the mattress without tension and wrinkles. It is also worth considering that knitwear has a two-layer weaving, where the upper cotton layer touches the human body, and the lower one is a mixture of viscose and polyamide, which improves the strength of the fabric. Also, the volumetric weave has better ventilation ability. If the knitwear is hooked, then the hole can be easily repaired with a needle, simply by gathering the loops together. But in this case, "arrows" are formed in jacquard.
The mattress must have a winter and summer side. Recently, double-sided mattresses with different finishes on their sides have become popular. One is designed for winter, it is warmer and softer due to the quilting of wool or woolen cover. The summer side seems to be cooler, its cover is made of natural cotton. Due to the different sides, it is recommended to turn the mattress at least a couple of times a year. While this seems like a good design, it has some serious drawbacks. The fact is that the design of double-sided mattresses has to be made symmetrical, which gives a larger number of layers, and therefore increases the cost of the product. Due to the slatted base, the surfaces of the double-sided mattress are more deformed, since they are made much softer than the lower surface of a regular mattress. Therefore, over time, the layer of quilting will wrinkle, even if the mattress is turned over regularly every three months. And in modern warm apartments, the temperature changes little throughout the year, as a result, the advantages of such a product simply come to naught.
