Ergonomics is a subject about the study of human-being.It is a science of making the workplace to meet the needs of users. Ergonomics aims to improve efficiency and productivity while reducing discomfort.
Why should chairs to be ergonomic?
First,take a look at the angle of your computer screen or the height of your desk. Think about whether your eyes are tired or your wrists hurt from typing at the end of a stressful day. The correct understanding of ergonomics means that the tools can be adjusted to meet the needs of users, focusing on the correct posture, so as to reduce the impact of repeated movements, so as to prevent daily work strain.
The use of computers and the rapid changes in the modern workspace have greatly increased the demand for ergonomics. Desks, chairs, computer screens, keyboards and lights, whether in the office or at home, need to be evaluated. You can only maintain fixed posture using ordinary office chair, which cause muscle stiffness.However, ergonomics can meet the needs of different users according to their own characteristics, allowing us to maintain a balance between sitting and standing effectively defeating the physical damage caused by sedentary behavior in the office.
How are ergonomic office chairs manufactured?
Actually many people has a misunderstanding for ergonomic chairs, they consider that functional chair equal to ergonomic chair, so that they think if the chair back, depth, height can be adjustable it should be ergonomic . In this article, let take a look at how ergonomic office chairs come out from the design to mass production.
Sep1: Research, testing, and multidisciplinary cooperation on sitting habits:
Herman Miller conducts tests for different populations in the way of research to collect research data, which is finally improved by experts in different fields
For example, some tests measure a person's comfort while sitting, while others measure a person's metabolic variables-such as heart rate (hr), respiratory rate (rr) and co2 output-to compare the relationship between the performance of different chairs and the user's health. The results of all these research processes enable them to better give the design requirements and bring the unique quality of the product. They study not only the dimensions and differences of the human body, but also the way the body moves. They study the structure of the human body, bones, muscles, and how the body should move to make it feel comfortable.
To learn more about physical changes at work, steelcase also conducted a global survey of sitting posture, observing the different sitting positions of more than 2000 people on six continents. With the integration of new technology and new behavior, nine new sitting positions have been born. However, the problems caused by these new positions have not been fully solved in the existing seat solutions.
Hookay has conducted an in-depth study on various sitting positions of the human body. The spine is the core transmission shaft of the human body, and the spine has to bear part of the weight no matter what posture it is. The main force-bearing of the spine is concentrated in the back, waist and buttocks. Under the condition that the back can not be slowly pressed for a long time, the compression of human muscles leads to unsmooth blood flow, enlarged capillaries and oppressed nerves lead to soreness, slow response and slow work efficiency, while the waist is the core compression area of the weight of the upper torso. Lumbar deformation, hyperplasia and other problems are caused by the lack of efficiency of the top waist.
Therefore, there are three main points for the chair to conform to ergonomics: 1. According to the physiological curve of human spine, the curve of the whole back of the chair is naturally fitted to the curve of the back ; 2. In line with the waist-hip seat depth ratio, reasonable and chair width corresponding to the human waist and back coverage; 3. It can provide comfortable feedback, tension, and the strength of support that complements the sense of wrapping.
Step 2 Design:
Efficient seat design should begin with understanding the scientific nature of the seat and the contact parts between the human body and the seat. On the other hand, the overall design of Hookay seat is completely consistent with the physiological curve of human spine, and the curved surface of the whole chair back naturally fits the Radian of our low back curve. Evenly disperse the pressure of the waist and back muscles, after the back is supported enough, the waist and buttocks will disperse the force, and the muscles will be relieved.
Different work modes require different solutions, and the concept of dynamic support for seats also needs to be continuously developed to keep up with the ever-changing workflows and office appliances. Hookay ergonomic chair has created the concept of dynamic lumbar support, which brings brand-new ergonomic support for improving the physical and mental health of users. it also provides employees with corresponding ergonomic seats as they move in their working posture.
It's not just a matter of comfort. There are many beautiful and comfortable chairs in the world, but they don't take into account the impact of these people sitting on them for hours every day. The design of the chair should be able to naturally adapt to the dynamic changes of the body, especially the lumbar, so that people can get close support in various sitting positions. In this way, the problems caused by static sitting posture can be effectively avoided. It can even help improve the physiological function of sedentary posture.
Today the world becoming increasingly diverse and extreme stature is becoming increasingly prominent. The height adjustment of ergonomic chair from Hookay can meet each user's body size, body shape and different sitting posture preferences.
Sep3 manufacturing, testing: mainly for seat back, seat cushion, chair castor, gaslift test.
1) gaslift inspection:
2) seat cushion nailing.
3) rotation test of castor.
4) tension test of chair back.
5) compressive gravity test of seat cushion.
6) parts assembly
All office tools are developed in accordance with the nature of ergonomics. Users can easily adjust to different environments. All products are designed to promote the daily movement and high efficiency of users in the office environment. Of course, the performance of quality inspection is also very important. At present, many domestic ergonomic chairs on the market pay too much attention to the diversification of functions in order to meet the diversified needs of consumers, but some international ergonomic chair brands such as Herman chair Miller, steelcase, HAWORTH, and a very small number of domestic brands,they pay more attention to the sustainable development between products and the environment:
In addition to the sustainable development between the product and the environment, as well as the strict quality test and check of the product itself.
1) BIFMA certification is the key standard for testing the quality of an ergonomic chair (if there is no BIFMA certified ergonomic chair on the market, it is not recommended to buy it . After all, a good ergonomic chair can buy the most powerful support for yourself and your family.)
2) Brand gaslift: BIFMA certification, SGS certification, Pay attention to whether the gaslift is SGS/BIFMA certified. The nitrogen concentration in the pressure rod of a qualified SGS certified pressure rod is ≥ 90%, the endurance can reach 200-250kg, it can rise and fall 300000 times without damage, and can be used normally for five to eight years.
A good ergonomic chair can last as long as 12 years if you sit for 24 hours a day. On average, you only need to spend a small amount of money to buy the strongest support for yourself and your family. Why not?
