Ergonomic chairs help maintain good posture and relieve your lower back pain!

Feb 16-2023

After sitting in the office for a long time, a ergonomic chair can save your back pain! On a busy and tense eight-hour day, nearly seven hours are spent sitting on a work chair. If the office chair is uncomfortable or the sitting posture is incorrect, the cervical and lumbar spine will be in a tense state, and there is a risk of cervical and lumbar disease.

A caring office chair can provide support to fit your waist and shoulders, protect spinal health. There is an ancient Chinese saying, "To do a good job, one must first sharpen one's tools". How can you work well if you are sitting uncomfortably? Today we will talk about it.

1. What aspects should be considered when choosing a good ergonomic chair?

1. Good chair back

The chair back can be said to be the soul of a good office chair.

Firstly, the design of the chair back of a good office chair must be in line with the natural curve of the human spine, i.e., the thoracic spine is convex backward, and the cervical and lumbar spine is convex forward. Therefore, a reasonably designed work chair should have the following three support points for the human back:

(1) There is a curved surface that can be adjusted at the upper back to support the convex thoracic spine.

(2) There is an adjustable lumbar cushion at the lower back to support the convex lumbar spine.

(3) There is an adjustable neck support. A neck pillow that can be adjusted is crucial for supporting the convex cervical spine and relieving fatigue.

2. Two parameters to be considered

(1) The height and leg length of each person are not the same. A good ergonomic chair should have an adjustable seat cushion height.

(2) The depth of the seat cushion should be deep enough and adjustable to release the pressure on the lower part of the thigh, promote the circulation of the lower limbs, and not give a feeling of slipping off the chair.

3. The seat "should be stable"

Office work often requires movement, so an office chair with casters has become the mainstream. If you are careful, you will find that a general caster office chair is supported by a five-point base, which also meets the stability requirements and will not tilt over. At the same time, the casters should also choose more durable ones, which is also to enhance the stability of the chair.

4. Breathable material

Generally speaking, the leather of an ergonomic chair is divided into two types: mesh and leather. Each has its own characteristics: leather is easy to clean but has poor air permeability; mesh has good air permeability but is not warm.

However, when it comes to the material of the office chair, breathable materials should be chosen as much as possible. Even if the office is air-conditioned at a constant temperature all year round, which is comfortable for the warmth and cold, because the human body is in close contact with the chair, materials with good air permeability are more conducive to dissipating heat, and the human body will feel more comfortable.

5. The armrests are connected to the chair back

The simplest way to judge the quality of a chair is to see if its armrests are connected to the chair back or the seat cushion. For a chair that connects the armrests to the chair back, when leaning back, the armrests can maintain the same angle as the person's back, providing comfortable arm support.

2. What harm can a bad ergonomic chair do to the body?

The comfort level of the back, neck, and waist determines the fatigue of the thoracic vertebrae, cervical vertebrae, and lumbar vertebrae, respectively.

A normal human spine has three physiological curvatures. These curvatures do not grow on a straight line due to physiological needs. The thoracic spine is convex backwards, and the cervical and lumbar spine is convex forwards. From the side, the spine is like two connected S's.

Due to this physiological characteristic, the waist and back cannot be placed on the same plane. Therefore, in order to achieve a comfortable sitting posture, the design of the chair back should conform to the natural curve of the human spine, which can maintain the convexity of the cervical and lumbar spine and the concavity of the thoracic spine.

If the ergonomic chair is not good, people will sit uncomfortably and will inevitably slack off in order to find the most comfortable position. They cannot maintain the correct and healthy sitting posture for a long time, and their cervical, lumbar, and thoracic vertebrae will remain in a tense state, causing exhaustion and huge strain.

More than half of white-collar workers in offices suffer from cervical or lumbar diseases, which are caused by prolonged incorrect sitting posture and excessive fatigue. Therefore, choosing a good ergonomic chair is essential for work.
