8 hours to work at the computer, go home from work to sit and surf the Internet, is nowadays the normal life of many white-collar workers. In addition to the bed, the longest accompany them every day is the chair under the buttocks.
Maybe you haven’t realized that an uncomfortable work chair can become a healthy “invisible killerâ€; maybe you realize that the seat under the buttocks is just as important as the seat on the workplace, but you know how to get promoted but you don’t know How to choose a chair.
Now tell you the pick of the work chair. There is no limit to the sea of ​​work. Choose a chair and look for it.
How to buy a chair buyer and seller can not understand
Will you choose the right computer chair? After investigating the 10 white-collar friends around, the reporter found that they knew almost nothing about how to select a computer chair. The computer chair at home was either sent to buy a table, or just picked a suitable price. Some people sit for a long time, the body will go down, and some people sit in front of the computer, their feet are hanging.
The reporter went to a furniture store in the city and asked a well-known brand furniture buyer how to choose a suitable computer chair. The Purchasing Manager said, "I'm not quite sure. You'll just sit for a while and feel better. Which one is more comfortable to buy, our computer chair is mostly for gifts when you buy furniture." Computer Chairs that are closely related to our health The people who bought and sold did not understand it.
The price is too low to be a good chair
A chair, it seems simple, but the structure of each part is also complicated. In the field of civil furniture, few people can really understand it. The reporter consulted experts in the field of office furniture.
"The computer chair below 200 yuan should not be bought, because such a low price can't guarantee the quality at all." Yi Cong, the general manager of Sichuan Qingtian Furniture Industry Co., Ltd., who has been in the office furniture field for 15 years, said openly. At present, the domestic computer chair market is very confusing and the market competition is fierce. Many small businesses do not have brand advantages and adopt low-price competition. In order to reduce costs, these companies cut corners on various parts of the computer chairs. Consumers are even less knowledgeable about professional computer chairs, and purchases are very arbitrary.
The price can be used as a rule to judge the quality of the computer chair, but can you really buy a good chair at a high price? "The expensive chair can't be a good chair, but it's a good chair but it's not cheap," said Lin Lan, a Milan office furniture sales representative who has been selling office furniture for many years in Chengdu.
To understand the structure of a good chair is standard
A good computer chair should consist of five parts: a five-star foot, a pneumatic pump, a chassis, a seat board, and a back board. Only the various members perform their duties and coordinate with each other to form a comfortable and durable chair.
The first part is the five-star foot, the five wheels that slide the computer chair. They bear the weight of the human body and are related to the durability of the chair. The wheels of many cheap computer chairs are made of plastics or even waste plastics. The physical properties of plastics are not good, the summer is too soft and the winter is too brittle, and people often run into situations where the wheels are suddenly broken. A nicer wheel adds the right nylon to the plastic to increase its wear resistance. Of course, stainless steel and aluminum alloy cast wheels are even better.
The second part is the pneumatic pump, which controls the computer chair to go up and down. Insiders pointed out that the difference between a good air pressure pump and a poor quality air pressure pump is about 7 times. The poor quality of the air pressure pump's steel wall is very thin, the valve is not closed tightly, and it will leak for a long time, resulting in the chair cannot lift. Lin Biao teaches everyone a way to check whether the air pump is good or bad: lift the chair to the highest position and then put it down bit by bit, if the chair falls down to the end, if there is no rebound feeling when it falls, the quality of the air pump It's not good enough.
The third part is the chassis. This is the brain of the chair. Almost all functions are achieved through the chassis. The chassis can manipulate the angle of the chair's reclining or leaning forward, as well as the degree of softness and hardness. The chassis function determines whether the entire seat can be tilted or only the backboard can be tilted.
The fourth part is the sitting board, which must conform to the curves of the human buttocks and thighs. The density and thickness of the sponge covered on the seat board are related to the comfort of the seat. If the sponge above is too thin and the density is not enough, the seat will be “insecure†after 3 months of sitting.
The fifth part is the back panel. This part must meet the ergonomics. The closer to the curve of the human spine the better. The elasticity and toughness of the back panel are important factors to determine whether it is comfortable.
The chair will not sit well
Most of the upper body's strength is concentrated on the pelvis. Sitting on a chair for a long time can cause fatigue in the buttocks and pelvis. Too little venous activity can cause pain syndrome and other diseases in the lower back.
Vertebral venous congestion also increases the pressure on the lumbar nerves.
Intervertebral discs only get nutrition through diffusion when they are not deformed or in motion. In order to ensure the elasticity and toughness of the intervertebral disc, it is necessary to supply the liquid, otherwise the continuous pressure will lead to a decrease in the abrasion resistance and even the sagging of the intervertebral plate.
If the muscles remain static for too long, they will cause circulatory disturbances and affect the metabolism of the lymph system.
The physical examination center of West China Hospital of Sichuan University recently discovered that after the medical examination of employees in a public institution, as the employees are mostly between the ages of 30 and 50, up to 70% of them have cervical disease. Wang Youjuan, director of the physical examination center, told reporters that the incidence of cervical spondylosis is 50% higher than that of the general population in long-term working groups such as clerks and medical personnel.
This kind of white-collar disease occurs in young people aged 30 to 40. They work long hours, and their muscles and joints are in a state of high tension. Because of the fast pace of work, they do not have time to move their muscles. Cervical and lumbar diseases are common.
Prevention and mitigation of cervical and lumbar spine diseases, in addition to doing one or two hours after work to do neck and waist exercises. Experts believe that a chair that can give full support to various parts of the human body and allow the joints and muscles to fully relax can also prevent and reduce the occurrence of cervical and lumbar diseases.
Buy a computer chair to try five parts
Experts in the field of office furniture have given the basic principles for purchasing a computer chair: one can adjust sitting posture, conform to ergonomics, provide support for the arms and shoulders, provide strong support for the lumbar cervical spine, and relieve muscle and joint pressure The chair is the scientific work chair.
Shoes don't fit. Only wear them to know. Buying a computer chair is like buying a shoe. Be sure to try it. But what exactly do you try and what details should you pay attention to when you sit down to buy a computer chair that is good for your health?
A seat cushion angle: sitting in a computer chair, the legs naturally sagging, and the sitting board is basically 90 degrees, the feet can be flat on the floor or on the mat, the knee is slightly lower than the buttocks. Due to the different heights of people, a chair with adjustable height and seat depth allows people of different heights to sit comfortably.
Second test backrest angle: The backrest of the computer chair needs to have a reclining function. The seat can be tilted in its entirety (this position relieves pressure on the legs), the backrest angle can be adjusted, and it can be locked firmly. These functions are very important. Leaning back can relieve neck and shoulder pressure. Leaning forward slightly can reduce the pressure on the lower back to make you more comfortable.
Three test waist support: a chair with a waist support function, can give enough support to the waist, can effectively alleviate the pressure on the back. For a better chair, the lumbar support function can also be adjusted according to the needs.
Four-hand armrest adjustment: The armrest relieves tension in the arms and shoulders. Adjustable armrests help to help reduce stress. Set the armrest close to the height of the table to maximize the weight of the arms and shoulders.
Five-Head Pillow Function: The time spent on desk work is long, and it is necessary to lean back and forth from time to time to stretch the neck. The headrest on the chair can relax the head and neck. A good computer chair should have the function of adjusting the height and curvature of the headrest.
