How To Choose A Safe And Qualified Office Chair?

With the development of science and technology, more and more office workers and netizen are working in front of computers. Sitting in front of a computer desk for an extended period and bending their bodies puts muscles, ligaments, fascia, capsules, and other soft tissues in a state of tension for a long time. After fatigue, the powers of the neck are stretched beyond their physiological load. As a result, diseases such as cervical spondylosis, periarthritis of the shoulder, and strain of the lumbar muscles are becoming younger.

So how should enterprises buy office chairs?

Office headrest

Sitting in the office to see the computer in addition to the cervical vertebra and neck is uncomfortable, so you need a headrest. The headrest can support the neck and head and ease the fatigue of the neck; the headrest is recommended that you can move up and down the headrest. The best position to adjust the headrest is to adapt to the third to a seventh segment of the cervical spine. The choice of headrest material is also critical. The best option for the material headrest is mesh, which is relatively fresh and breathable. While the sponge headrest with a bit of heat, it is more comfortable than mesh.

Can the chair adjust the sitting position?

The first criterion for an office chair is whether it can help the user adjust to the best sitting posture because only by maintaining a good sitting posture can you minimize the damage to the body. Choosing a chair with a slightly reclining backrest, preferably one with adjustable chair height, backrest height, and tilt, is recommended. Height suitable, lower limbs naturally sagging, feet flat on the ground, slightly higher than the hip joints, hip back, the body slightly later leaning back, gently leaning on the chair back, so that the upper body and leg angle maintained at about 135 degrees. Such a sitting posture will approximate the natural "S" when standing.

Cushion comfort and material

The comfort of an office chair is inseparable from the seat cushion because it has the longest contact time with the human body, and it is also where the human body has the most significant contact area on the seat. Therefore, the comfort of the seat cushion directly affects the person's convenience. Generally, a good seat cushion will be very thick. When purchasing an office chair, you can observe whether it has a concave curve. Generally, if there is a curve, the fit is better and more comfortable to sit on. The cushion material is usually divided into mesh, fabric, and leather. The comfort of the fabric and leather is vital, but it is too hot in summer, and the comfort of the mesh is poor, but it is easy to clean.

Adjustability

The office chair should be adjustable. Everyone's height, weight, leg length, and waist length are different, and each person's skeletal muscles are unique. It is necessary to work to make the office chair a most comfortable posture. The chair has good adjustability. These adjustments are reflected in the adjustable headrests, backrests, armrests, and seat cushions. And not only can you adjust the height, but also the inclination.

Stability of mechanism

Whether the mechanism is stable or not, its material choice is significant. As we all know, the heavier the mechanism, the more stable the office chair will sit. The mechanism of a good office chair is generally made of iron or aluminum alloy, while the poorer ones are made of ordinary Engineering plastics. The aluminum alloy mechanism has a solid load-bearing capacity. In addition, during the purchase process, you need to check whether the seat base is equipped with explosion-proof steel plates. To ensure safety, regular office chair manufacturers will install an explosion-proof steel plate that is not less than 2 mm at the connection between the gas lift and the seat cushion to prevent the gas lift from exploding during use.

Office armrest.

Some office chairs may not have armrests, but it is best to choose an office chair because it can reduce the pressure on the lower back, relieve tension in the shoulders and neck, and provide support when writing and reading. Usually, when using the computer in the office, the hand is mainly suspended, so the burden on the arm is heavy. If the armrest can adjust to the ideal height, it can support and relax the arm. Ideally, the armrest should be an adjustment, cushioning, and comfort.

Safety of gas lift .

The quality of the gas lift is an essential element in determining the office chair's safety factor. It is reported that the reason for the explosion of the office swivel chair: was mainly caused by an inferior gas lift. Therefore, when choosing a swivel chair, the first thing to check is whether the gas lift is certified by authoritative organizations such as SGS/BIFMA/TUV. The gas lift used by ZHI XING and most well-known office chair brands is mainly gas lift that has passed several safety certifications. In addition to the manufacturer's trademark on the rod body, the gas lift will print with national certification marks and the certification qualification. We can identify the pros and cons of the gas lift accordingly.

Chair base

The chair's base is the key to the load-bearing of the chair. When choosing, you need to see its material, load-bearing, and inspection standards. The materials of the chair base are PP, PE, nylon, steel, and aluminum alloy. The strength is sorted, aluminum alloy >iron steel > nylon > PE > PP.Nylon, iron steel, and aluminum alloy are commonly used in the industry, and nylon is the most cost-effective, so Nylon material is a material with a high usage rate on the market. Qualified nylon chair legs have good toughness, tensile and compressive resistance and reduce the damage of bumps. However, those who are tall and heavy are recommended to choose aluminum alloys.

Pay attention to six points when using office chairs.

1. Please keep the indoor ventilation so as not to be too dry or humid.

2. The leather has strong absorption. Please pay attention to anti-fouling.

3. Use a clean towel dipped in water to wring it out once a week, repeat light wiping, and then dry it with a dry towel.

4. If there are stains on the leather/cloth, it can be wiped with foam and a leather cleaner. Do not use strong cleaning products to clean the leather.

5. If the drink is knocked over on the chair, immediately dry it with a clean cloth or sponge, wipe it with a damp cloth, and let it dry naturally. Do not dry it with a hair dryer.

6. There are stains on the steel chair frame. To keep its luster, wipe it with a clean, dry cloth. In case of stubborn stains, spray luster cleaner on its surface and then wipe it with a flannel to make it as bright as new.
