Many people develop these disorders at a young age. The culprit is sitting for a long time. Besides that, the sedentary will also have a negative impact on the human cardiovascular system. In short, the sedentary can lead to a variety of diseases.

Some chairs are very comfortable to sit, we will not feel very tired after sedentary study or work,while some chairs can make us back pains after sitting for a short time. Why there is such a big difference? It is because that the “best seat” is designed to not only focus on attractive appearance, but also it can meet the human biomechanical characteristics. If the chair is not suitable for you, it will increase fatigue. The unhealthy sitting for long time will also cause myopia or hunchback, which will affect our health.

Among many external factors, it is undoubtedly one of the easiest and most effective method to change a more comfortable and more appropriate ergonomic chair for you.

 

3 Selection of Office Chair

  • Pay attention to the length, width and height

Taking into consideration of human anatomical peculiarities, the chair shall be designed to enable the weight of body resting on the human hips and skeleton. If the seat is slightly higher, it will more or less make the thighs under pressure, the leg muscles will feel uncomfortable after a long time; if the seat is too high to make legs hanging, it often leads to back muscles tension, and prolonged sitting can cause muscle pain. On the contrary, if the seat is too low to make the knee flexion angle of less than 90 degrees, it will also leads to the tension of back muscle. For this reason, the seat shall be designed to be slightly lower than the height of calf.

The surface length of seat shall be designed to enable the hips fully supported, but it shall be not too long. If the front edge of seat is too far out to squeeze the thigh muscles, it can lead to the soreness of thigh muscles. The front edge of seat shall be designed to leave a certain distance between the calves to ensure that the calves can move freely.

The surface width of seat shall be designed to enable the hips fully supported, and it shall leave an extra space to enable us adjust the sitting position freely. The seat is designed to be 53.3 width that can meet the needs of most people.

 

  • Selection of backrest – Focus on design details

A comfortable office chair shall be designed to have backrest that can provide a suitable support for the back. When we sit on the stool without backrest for a long time, we can instinctively take some inappropriate posture to make the torso get support. It can make our chest and back feel uncomfortable, and cause back flexion and eye myopia.

A backrest which is too soft can make our back bend into a bow, which will increase the load of back muscle. If sit for a long time, we can also feel the back pain. Therefore, we should choose some harder backrests, so that it can provide full supports for our body without causing back bend.

The backrest shall be designed to be high enough to support the waist, and it shall make the waist joint free moving in principle. The upper edge of backrest shall not be higher than shoulder. The height from the upper edge of backrest to the seat pan shall be 33.1 cm, so that the backrest can exactly support the lumbar concave.

It is better that the backrest supporting the waist is designed to have some projections and show arc slightly, so that the backrest can be pressed into the lumbar concave to fully support the waist. The horizontal shape of backrest shall be consistent with waistline in a curve shape slightly. The bending shall not be too large, about 20 cm of arc shape is enough.

Besides, you shall select a seat that there is a gap of 20 cm between the bottom of backrest and the seat, so that the hips are not be squeezed when protruding backward.

  • Selection of seat cushion – The hardness of seat cushion shall be suitable

Many people like a very soft seat cushion. In fact, the softer the seat cushion, the larger the pressure area on the hip muscles, it is more likely to cause hip discomfort. It is reasonable to design a seat as hardness and cover some cloth cushion on it. Thus, it is beneficial for the body weight resting on the ischium process to the maximum extent, rather than pressing on the hip muscles.

  • Adjustability

The fundamental demand of our selecting an ergonomic chair is that has a strong adjustability, which can coordinate with our body to the maximum extent to provide supports for the key parts of our body, so as to achieve the purpose of decompression and relaxation.

Therefore, when you choose an ergonomic chair, the first thing you should consider is the adjustability of seat. On the basis of meeting your own needs, the stronger the adjustability of seat, the better the seat is. A good adjustability will bring you a comfortable and reliable support experience.

  • Rest function

The sedentary has another potential danger that can increase the workload of cardiovascular and cerebrovascular. If you take a proper rest, it can effectively improve the situation. How to have a rest in the office? There are many ergonomic chairs to be designed to increase the leg support, which can meet the needs of noon break for office workers. The chair can be turned into a recliner in seconds during lunch break. Don’t underestimate the lunch break for 20 to 30 minutes! By doing this, it can not only make you more energetic in the afternoon work, but also play a significant role on your health.

Thus, it is essential that you have an ergonomic chair in the company, so you’d better select an ergonomic chair with leg support for lunch break!
