Generally, the height of tatami bed is 15cm-20cm. If a tatami platform is set, there is a lifting platform inside, which can be set between 35 cm and 40 cm. Tatami platform can't be curved, only suitable for straight platform. Japanese tatami is generally 30 cm from the ground, while Chinese tatami is about 15 cm.

The tatami bed is composed of a bed, Simmons and a mattress, and is provided with a bed body, a bed body frame and a wrapping belt. The bed has four layers, and the packaging belt is sewn on the edge of the bed, and the bed frame covers the whole bed. According to the physical characteristics of the human body, the shoulders, pelvis, ankles and other prominent parts are given soft protection. At the same time, it has different functions such as relieving stress, improving sleep state, avoiding moisture accumulation, not breeding bacteria easily, and benefiting human health.

Extended data

tatami

Tatami is transliteration in Japanese, and it is called piling in Japan. In ancient times, its lifestyle was called banquet system and banquet system. Tatami originated in China, but its date of origin has not been confirmed.

There are signs that after Yao and Shun, the main lifestyle was tatami. Han Dynasty is the peak of tatami development. During the 400 years from Han Dynasty to Tang Dynasty, stools and high beds prevailed, while chairs gradually declined in China. The specific period when it was introduced to Japan, South Korea and other places has been impossible to verify. With the changes of the times, the mat house has also changed from a banquet (made of bamboo) to a tatami in Japan today, and it has been inherited and developed by Japan. ? There are seats in Xi 'an's royal mausoleum. Tatami is a kind of furniture woven from rushes, which is laid on the ground all the year round for people to sit or lie down. Most tatami in general families are designed on the balcony, study or hall floor of the room.

function

First of all, tatami is economical. It has many beds, carpets, chairs or sofas.

This function. According to estimates, the cost of "tatami" for rooms of the same size is only three to a quarter of that of western-style layout. Secondly, space can be used effectively. In the case of a small room, there is no furniture such as beds, tables and chairs, which can save a lot of space. This is in line with the fact that there are more people and less land in Japan.

Sitting on a soft sofa for a long time will relax the muscles of legs, hips and waist, while the muscles sitting on tatami will be in a state of tension, so there will be no fear of muscle relaxation. A professor published research results in a newspaper, pointing out that the grass fragrance emitted by "tatami" is beneficial to human body.

Tatami is closely related to Japanese Shinto religious ceremonies and tea ceremony, and many Japanese families still have tatami in at least one room. Japanese tatami is not only a kang mat and carpet, but also a ruler. In Japan, wherever you go, the area of each tatami is equal.

The Japanese word "tatami" is "Bi", and it is also translated as "straw mat" or "straw mat", but it is not accurate. Brighter and flatter than straw mats, thicker and harder than straw mats. Traditional Japanese-style rooms don't have beds, tables, chairs and benches. They sleep on it at night, put away their bedding during the day, eat on it and carry out various activities. For example, when guests visit, they can just sit on it and have tea and chat. Therefore, as soon as you enter a Japanese home, you must take off your shoes. It is very impolite not to take off your shoes, just like stepping on our bed in China.

Japanese people like tatami very much. Once, there was a program on TV: dozens of families raised money to build an apartment. The reporter interviewed one of them and asked them what they were dissatisfied with the house. The only thing the family felt was that there was no tatami in the room. Modern Japan has absorbed the western architectural style, and the room configuration has been very different from the past. Especially in big cities, most people live in modular housing.

But "tatami" is still loved by people. Most families in Japan are "in harmony with foreign countries": there are western-style rooms, sofas, coffee tables, cabinets, beds and tables, as well as harmonious rooms and tatami. Most Japanese still don't want to sit on the sofa, preferring to kneel on the ground. A Japanese lady told me that if I don't sit on the tatami, I always feel that my mood is unstable. Tatami is not only spread at home, but also in public places such as cinemas and auditoriums.

Japanese people can watch movies and sit cross-legged for hours while listening to reports, which really makes people admire their sitting skills. Tatami is also a handicraft. There is a "tatami" museum in Japan, which displays tables and chairs, coffee tables, screens and paintings made of "tatami" materials. The variety and exquisite workmanship are breathtaking.

kind

Tatami is made of rush mats and paper mats. Relatively speaking, straw mats are more breathable and suitable for bedrooms and infrequently used rooms. Paper is stronger and waterproof, suitable for children, saunas, teahouses and rooms with high frequency of use. There are both traditional plain faces and many modern patterns. Weaving techniques include plain weave, twill weave, check weave and jacquard weave.

1, straw core: straw core is the most common in the market, which is a traditional practice. Its disadvantage is that it needs to be aired frequently and is afraid of humidity. It's easy to grow hair and bugs after getting wet. And it's not very flat With the continuous improvement of living standards and the acceleration of work rhythm, geothermal energy appears. So fewer and fewer people buy it.

2, non-woven fabric core: the word non-woven fabric is very common. It is an environmentally friendly and degradable material, and some clothes are non-woven. The knitting of clothing fabric is warp and weft knitting, and the tatami core is laminated knitting, which makes the effect more stable. This is also the reason why tatami with non-woven core is not easy to deform and not smooth.

3, brown core: brown core is suitable for mattresses, tatami is not easy to deform, and it is basically not sold in the market.

4. Wood fiber board core: Its advantage is flat and moisture-proof, but it can't be used for geothermal, because it will be crisp when heated.

5. Bamboo charcoal core: the moisture absorption rate of charcoal is 14 water, and that of straw is 18 water. So it is impossible to use carbon to prevent moisture from straw. A simple experiment: put a piece of bamboo charcoal and the same straw together, which is usually the first to get wet. So when there is moisture, the straw is absorbed first.

In Japanese style, returning to nature is the biggest feature. No matter in the design of color, function and shape, we advocate being close to nature and emphasize naturalism, so that users can feel in nature. For example, Japanese-style courtyards are unique and emphasize the contrast between indoor and outdoor, which contains profound philosophical thoughts and oriental culture in the placement of Shi Jing, the positioning of plants and the layout of landscape construction. Flower arrangement and bonsai are indispensable and placed in every corner of the house. It is not difficult to understand why even the placement of teacups or the corner of a bathroom should be matched with flower arrangement, and the mutual modeling and matching of various natural elements are indispensable.

At the same time, the Japanese pay attention to Zen, indifferent and quiet, fresh and refined, so most furniture emphasizes its functionality, less decoration and embellishment, simple shape, mostly straight lines, and luxury and luxury styles are almost impossible to appear in Japanese homes.

use

Tatami plays an important role in Japanese life. As early as the end of 16, Japanese society had the practice of building houses according to tatami distribution. Tatami is so important in Japanese family culture that tatami is not just a noun. The area of a tatami is 1.65 square meters. In some parts of ancient Japan, the amount of house tax was determined by the number of tatami sheets.

It is especially suitable for young people who live in big cities and are busy day after day, which can relieve fatigue well.

5.5cm thick grass board not only plays the role of cooling and moisture insulation, but also absorbs moisture, conducts heat and keeps constant temperature. Because of its own weight, it is flat, which reduces the uncomfortable feeling of the mat because it is thin or rolled up, and it is more beautiful and comfortable because of the exquisite surface and the reinforcement of the edge. And because of the convenience of standard size and the randomness of tailoring, no matter how big the space is, the tatami feels like a whole without any obstacles.

Tatami is a natural environmental protection product. It is absolutely beneficial to human health and longevity. First of all, it passes through the qi of heaven and earth, walks barefoot on it, and can massage meridians all the time, relax muscles and promote blood circulation.

Children don't have to worry about falling when using it. He can also prevent bone spurs, rheumatism, spinal curvature and so on.

Tatami is smooth, the grass is flexible, breathable, light green in color and natural in fragrance. The rooms paved with it are sound-proof, heat-proof, durable, portable, luxurious and exotic. Tatami can show the largest space in the smallest range.

With the cultural and economic exchanges between China and China, tatami began to appear. Tatami, as a household product, has moderate soft and hard texture and promotes the growth of children's bones. It is also beneficial to the relatively fragile physical recovery of the elderly. At the same time, it also has the advantage of flexible use. It can be used as a mattress or even directly as a bed. Conditional rooms have a platform with tatami on it, which can be used as bedrooms, tea rooms or other leisure and entertainment rooms. Coupled with the characteristics of green and practical, it has been loved by many people in China.

At present, the specifications of tatami produced in China are 1.9 meters long and 0.9 meters wide, and sometimes it can be customized according to the room size. There is a traditional Japanese room table in the middle. After tatami and its lifestyle entered China, most people in China chose the improved electric lifting platform. Compared with the traditional room table, this kind of lifting platform has the advantages of saving space and being convenient for users. When not in use, it is seamlessly combined with the ground; When in use, press the electric switch, and it will slowly rise to a suitable height, so that you can drink tea and chat, regardless of the sitting position. At the same time, there is space under the base to accommodate the legs of users, which is very suitable for the habits of China people.

history

Tatami Modern Chinese is usually transliterated as tatami, tatami, tatami and so on. And Zhongshan insight is transliterated as Zami and pedal cotton, with irregular words. Tatami is the perfect crystallization of life culture for thousands of years and the condensation of wisdom of Chinese ancestors. The origin of tatami can't be verified, and it was used in Yao and Shun dynasties. The earliest literature describing tatami originated in the Western Zhou Dynasty. At the peak of the Han Dynasty, "seats" swept across the country. It has been nearly two thousand years since China was introduced into Japan in the prosperous Tang Dynasty.

According to the survey, tatami culture has been widely spread all over the world. In Africa, Southeast Asia, South America, Yunnan Diaojiaolou residential area, Mongolia, Japan, South Korea and North Korea nomadic areas, there are different forms and different stages of living and living styles. Seating is not only the inevitable choice of primitive inhabitants, but also runs through all stages of the development of human civilization, and is also moving from rural areas to cities. From tents (yurts), stilts with stilts and heated kang (Korean warm beds), from open garden houses to prefabricated houses (buildings), from rough to exquisite, from living space to emotional space with spiritual influence.

Japanese tatami manufacturers spare no effort to promote tatami to the public and don't want it to become history. According to Xinhuanet, Japan Tatami Industry Promotion Association has been committed to the revival of tatami in Japan, encouraging people to return to the traditional lifestyle, including letting tatami "go home". Thanks to many efforts, the tatami industry is recovering, and many apartment residents begin to move square tatami into the living room, hoping to regain the tradition and build a "Japanese harmony".

manufacturing process

Traditional handicrafts

Traditionally, tatami is woven from rushes, tied with straw, and foamed plastics are also used. There is a uniform standard for the shape and size of tatami, which is bound with tapestry or black cloth. In the era when most Japanese lived in houses with land, tatami was a luxury enjoyed by wealthy families because some materials needed to be imported. Moreover, the traditional tatami is plain tatami with no pattern on the surface.

Modern craft

Modern tatami is made of high-quality straw with advanced Japanese technology and equipment. After high-temperature fumigation and disinfection, it is pressed into semi-finished products, sewn by hand, covered with natural mats, and wrapped with decorative ribbons on both sides to make finished products. A good quality tatami weighs about 30 kilograms. The tatami just made is grass green. If it is used for a long time, it will turn into bamboo yellow due to oxidation in the sun, and it is also very beautiful. Tatami consists of three layers, the bottom layer is insect-proof paper, the middle layer is straw mat, and the top layer is rush mat, with cloth on both sides, and the edges are generally traditional Japanese patterns. The standard thickness of tatami is 3.3 cm and 5.5 cm.

After entering the modern era, with the improvement of production technology and the change of people's aesthetic psychology, embroidered tatami appeared in Japan, that is, various patterns and patterns were embroidered on the surface of tatami by using advanced production technology to meet the different aesthetic and decorative needs of users. And with the entry of western lifestyle, the floor lifestyle of modern Japan has also begun to change. In some Japanese families, people no longer sleep directly on tatami, but put beds on tatami, and people sleep on beds. At this time, tatami has almost become a floor paving material, equivalent to a carpet.
