1. The origin of ergonomic chairsThe concept of ergonomic chairs can be traced back to World War II, when pilots needed to carry out engineering modifications to their chairs for long-term flights. The one who really brought ergonomic chairs into the office field was a profession that required long-term sitting and was rich - programmers.The development of ergonomic chairs in China is also accompanied by the rise of the Internet industry. In order to allow employees to work overtime, the bosses are really well-intentioned. Some wealthy bosses have equipped their employees with more comfortable chairs.At present, China has become the world's largest ergonomic chair market. Shouldn't the design for Chinese people also be based on a sample library of Chinese people's own height and body shape data?2. Are ergonomic chairs really safe?The more comfortable a chair is, the more complicated the engineering is. An ergonomic chair is mainly composed of casters, a five-star rod, a gas pressure rod, a base, a seat, a backrest, armrests and a headrest.Five-star rod: It is responsible for bearing weight. The material, weight and reinforcement are basically proportional to the price, but it does not have much impact on the use.Gas pressure rod: It is the core component of a chair and one of the most important components related to safety. At present, the commonly used gas pressure rods on the market are 2-4 levels, and 4 is the highest level. Level 2 gas pressure rods are often used in chairs with higher heights such as bar chairs, and level 3-4 gas pressure rods are mostly used for office chairs and ergonomic chairs.Chassis: It is the most challenging for the manufacturing ability of chair manufacturers. It is located above the gas pressure rod. The cheaper the ergonomic chair, the more similar the chassis looks. The chassis of the hundred-yuan level looks like a face-to-face.The evaluation results show that the regular product is just broken; the gas pressure chair in the second-hand market exploded; and the three-no products not only exploded, but also caught fire, and the scene was terrifying, so you must make sure it is a regular product before buying.3. Why do you need to buy an ergonomic chair?1. Harm of improper long-term sittingWaist injury: If you neglect exercise and sit in one position for a long time, the muscle strength and endurance of your waist will become worse and worse, which is very easy to cause lumbar muscle strain and low back pain. In addition, long-term sitting will also compress the lumbar intervertebral disc, especially for people who often write at a desk or operate a computer. This compression will not only reduce the elasticity of the intervertebral disc, but also squeeze it out of its normal position, causing lumbar disc herniation.Neck injury: People who sit for a long time will easily form cervical bone hyperplasia, calcification and ossification of the cervical ligaments, and stiffen and straighten the cervical spine, resulting in different types of shoulder and neck discomfort.Leg injury: After sitting for a long time, especially if you sit in an incorrect posture for a long time, your waist will be severely compressed, and the lumbar nerves will extend to the knees, causing knee pain.
The above is the correct sitting posture, with your head straight, shoulders flat, spine straight, and chest straight. The thighs should be relaxed symmetrically, and the calves should be placed vertically and parallel. Put your feet forward straight and use your arms evenly. But with busy work and long hours of sitting, you really can't take care of the correct sitting posture.4. What are the benefits of ergonomic chairsHead: The height and rotation of the headrest can be adjusted, which can make the user's cervical spine naturally fit the headrest, standardize the user's sitting posture, and increase office enjoyment. When the height of the headrest fully supports your cervical spine, it is the best position.Chair back: The best support position for the waist is the third and fourth vertebrae. The entire chair back can be adjusted in height, which can easily meet the needs of different users and reduce most of the human weight borne by the lumbar vertebrae.Lumbar support: Separate movable lumbar support, the rebound force is concentrated on the movable lumbar support, giving the user the closest support. The movable lumbar support adjusts the curvature to make the entire lower back relax and fit comfortably to the waist and back, so that the spine can be relaxed, thereby relieving the fatigue of the spine.Armrest: Adjust the height and angle of the armrest to make the hand and the table transition more smoothly to prevent the occurrence of mouse hand.Freely adjustable angle, stepless locking, arc-shaped back design, bow-shaped frame strength and elasticity treatment, arc-shaped streamlined armrest treatment.The role of ergonomic chairs is actually to correct our sitting posture and protect our waist, shoulders and neck.5. The difference between ordinary chairs and ergonomic chairs1. Good support
2. Stronger adjustability
3. Good material and not stuffyThe biggest feature of ordinary chairs is that they are not adjustable. At best, they can just let you sit down. The experience is average and suitable for short-term sitting.
In the sitting posture, only the spine is less stressed when sitting backward and sitting upright, while the force is the greatest when sitting prone.The ergonomic chair can be freely adjusted according to the user's body shape and the stretching changes of the sitting posture. The best support point for real-time sitting posture can be achieved by adjusting the height of the chair's headrest, chair back, lumbar pillow, chair surface, and armrests.6. Choosing an ergonomic chair
It is most important to buy one that suits you according to your physical condition. Most ergonomic chairs can meet the needs of people between 155 and 185 cm. It should be noted that the cushion size of some chairs is relatively narrow or the seat is high, so you need to judge based on the detailed size before buying.
