Ergonomic chairs are designed to help you sit comfortably for a long time at work.

These chairs can improve your work efficiency and job satisfaction, but they can also reduce the risk of musculoskeletal injuries. Ergonomic chairs can relieve your low back pain for five reasons.

Improve comfort

The last thought

1. Correct posture

The most important reason why ergonomic chairs can improve low back pain is that their design can support your natural posture and reduce the pressure on your body. The back of the chair usually extends from the shoulder to the seat. There is a structure in the lower part of the back, which bends forward slightly to match the natural curve of the lumbar spine. This is often called lumbar support because it helps to protect the lumbar spine.

Adjustable armrests can support your elbows and forearms because your arms will naturally surround you. This allows you to use the keyboard and mouse without causing shoulder and arm muscle fatigue. Adjust the height of the seat so that you can lay your feet flat on the floor and bend your hips and knees to about 90 degrees. The backrest of some ergonomic chairs can be moved forward or backward to shorten the depth of the chair and prevent the front edge from cutting into the back of the knee.

2. Correct hip and pelvis alignment

The common cause of low back pain when sitting down is incorrect arrangement of hips and pelvis. The top of the pelvis should be kept horizontal to prevent it from leaning forward or backward. When sitting in the right position, the bone structures on the pelvic bones are said to be flush with each other. Located in the front and back of pelvic bone respectively. When these bony structures are in a horizontal state, your waist should be slightly arched and the protruding part should face forward.

If you swing from side to side, you should feel the pressure of the bone structure called the ischial tubercle. These are also called ischias because they should be the load-bearing parts of the pelvis when sitting. If you have ever sat on a hard bench, you may feel your ischial tubercle pressing into a hard surface.

3. Prevent shaking and leaning forward.

When you sit down, your lumbar spine will bend and your shoulders will roll forward, forming a lazy posture. In this position, your shoulder blades are far away from the thoracic vertebrae, and your head is extended forward or outward. When you look up at the computer monitor, your neck will move to a stretched state and further exaggerate the front head posture. If you continue to work in this posture, you may cause muscle strain, pain and headache.

Both internal and external factors can lead to laziness. Internal factors include limited hip flexion range, tense hamstring, obesity and weak trunk (core) muscles against gravity, which can not keep the spine upright. External factors are factors other than the body, such as the limitation of chair design. These include the seat depth is too long or too short, the seat back is too vertical, and the armrest is too low.

Ergonomic chairs may not change your internal constraints, but they are designed to correct external factors. Adjustable seat depth and back contour support the waist, prevent laziness and promote sitting in a proper position. Some chairs also allow you to adjust the angle or inclination of the back. Using properly adjusted ergonomic chairs can prevent laziness and head posture in front.

4. Reduce repeated bending of the body

The side effect of sitting badly on standard tables and chairs is that the body needs to bend over repeatedly to relieve it. This situation is likely to happen several times a day, and it will make your back ache. Sitting in an ergonomic chair with good back support can make you sit more upright. This can make you not need to move more, but effectively prevent the waist from adding extra pressure.

Improve comfort

Many ergonomic chairs are made of higher quality materials. Cushions and cushions to improve the fit. Some ergonomic chairs have extra lumbar support built into their designs. If the legs are short, you can lower the chair and slide the backrest forward to shorten the depth of the seat. You can also lift the armrest to support the elbow. The key to comfort is to be able to adjust almost every part of the chair to adapt to various body shapes and sizes.
