More and more people know that ergonomic chair is the first choice for office chair. But for many people, "ergonomic chair" is just a term. What is ergonomics, what is an ergonomic chair, they often do not understand. Today, we will give you a detailed introduction to the ergonomic chair.
What is ergonomics?
First of all, we will introduce ergonomics. It is a science that studies the relationship among human, machine and environment in the "human machine environment" system, and provides theories and methods for solving the problems of human efficiency and health in the system.
In essence, ergonomics is to make the use of tools suitable for the natural shape of the human body as far as possible. In this way, the body and spirit of people who are using tools do not need any active adaptation, so as to minimize the fatigue caused by using tools.
As for the ergonomic chair, as the name implies, the chair designed according to ergonomics is more humanized. No matter how tall or thin you are, you can find a comfortable sitting position and don't feel tired after sitting for a long time.
Such a chair can be called an ergonomic chair!
Can a chair be considered an ergonomic chair only if it meets the following conditions?
- Sitting on an ergonomic chair, the distance between the eyes and the computer screen is 50-70 cm
- The first line of the screen is about 3 cm under the line of sight
- When the arm sags naturally, the armrest can be at an angle of 80-100 degrees with the elbow, while not extending outward
- The waist and back are close to the back of the chair, leaving no space
- The knee will be higher than the chair, and a good seat will give blood to run
- Footboard should be in the end, do not hang your feet
Compared with the general office chair, the most important feature of the ergonomic office chair is its adjustability. You can easily adjust each part of the chair and adapt to your body size.
Sitting in an ergonomic office chair to work can bring many benefits to people:
- The weight of the human body that can bear the lumbar vertebrae, reducing the probability of spondylosis
- Reduce the burden on the blood system
- Reduce the pressure area of the buttocks and back, promote blood circulation of the buttocks and back
- Prevent the birth of the mouse hand
- Relieve the burden on leg muscles
- Prevent incorrect office posture and improve work efficiency
The design of the ergonomic office chair should consider 5 points:
When the ergonomic chair is being designed, it needs to consider the following 5 points:
The height of the headrest can be rotated and adjusted, the best position is that the height of the headrest fully supports your cervical spine. When sitting, the cervical spine not only fits the headrest naturally but also regulates the sitting posture.
This can effectively relieve the fatigue of the spine and prevent bone spurs or chronic spinal degeneration.
The material of the headrest is made of soft spots, so the comfort is naturally needless to say. Moreover, the hard material is easy to cause blood flow in the neck, causing headaches and dizziness.
- Chair back
The chair back can be said to be one of the most important places in the ergonomic chair. First of all, the chair back must fit the human spine. This can reduce the weight of the human body that the lumbar vertebra bears, even the body weight, protect the waist, and eliminate pressure points and heat episodes.
Secondly, the height of the chair back can be adjusted, whether it is a manual adjustment or automatic adjustment so that everyone with different weights can find different tilting strengths.
The elastic and adjustable lumbar support can play such a role: whether it is collaborating at a desk or typing on the keyboard, it can have perfect support for the waist.
- 4. Armrest
The height and angle of the armrest of the ergonomic chair can be adjusted, and the distance between the top, bottom, left and right can be adjusted. The correct height of the armrest should be adjusted to 90 degrees between the arm and the elbow. The arm should hang naturally without hanging the shoulder.
In this way, the hand and the tabletop can be smoothly transitioned, and the mouse hand can be prevented. When our hands are not supported for a long time or are poorly supported, it is easy to cause periarthritis or shoulder soreness.
In the ergonomic chair, the design of the cushion can not be ignored. When we sit in a chair, most of the pressure is borne by the hips, and a small part is borne by the thighs.
To reduce the pressure on the buttock's nerves and blood vessels, the cushion is best to choose a breathable elasticity. To be better for your hips is to be better for yourself.
This shows that the ergonomic chair can be said to be the "king" of the office chair. For those who work in the office for a long time, it is necessary to buy a comfortable ergonomic chair.
We recommend that you buy the brand's ergonomic chair, which is superior to general office chairs in terms of material, safety, comfort, and adjustment function.
The service life of an ordinary office chair is about 2-5 years, and the service life of a brand of ergonomic office chair is 10-12 years, or even longer.
Therefore, although the brand ergonomic office chair is a little more expensive, in the long run, it is obviously more cost-effective, and its comfort and health can not afford the general office chair.
