Points to note and pitfalls to avoid when purchasing an ergonomic chair
Let's take a look at the points to pay attention to and the pitfalls to avoid when purchasing an ergonomic chair.
1. Look at the adjustability
I mentioned above that an ergonomic chair is mainly composed of the chair back, base, headrest, armrests, air pressure rods, and chair legs. The adjustable ones include the headrest, chair back, base, and armrests.
(1) The main function of the headrest is to provide support for the cervical spine and prevent cervical spine pain from sitting for a long time. People of different body types need to adjust it to fit themselves. Therefore, the richer the adjustability, the better the compatibility with the body shape. 3D>2D >1D>Fixed. Currently, mainstream ergonomic chairs are basically 2D headrests.
3D: Supports up and down, front and back, and rotation adjustments
2D: supports up, down, and rotation adjustments
1D: supports up and down adjustment
(2) The chair back can be said to be one of the cores of the entire ergonomic chair. It mainly provides a reasonable and effective support for the waist, back and shoulders to maintain the healthy "S" shape of the spine and prevent excessive intervertebral disc pressure from sitting for a long time. cause deformation.
The first thing to consider when choosing a chair back is whether the design is reasonable. If the design is unreasonable, no matter how much adjustability you have, it will be of no use. You cannot try sitting on it when purchasing online, so it is more reliable to choose one from a big brand. The adjustability is divided into two parts, one is the chair back adjustment, and the other is the lumbar adjustment.
Generally, most mid-to-high-end ergonomic chairs support up-and-down adjustment of the chair back, which is mainly friendly to tall people. Tall people need to adjust the chair back a little higher to provide reasonable support for their waist, back and shoulders.
The lumbar support adjustment mainly adjusts the support strength and angle. This is more useful for thin people or fat people. You can adjust the support strength to suit your waist.
(3) The base mainly provides a support for the buttocks. Its adjustability mainly refers to the seat depth. An ergonomic chair that supports seat depth adjustment will be more compatible with the body shape. Small figures can adjust the seat depth a little smaller to prevent the seat from falling. Too deep to reach the back of the chair. For large models, you can adjust the seat depth a little wider to prevent the seat cushion from being too short and the legs hanging in the air.
In addition, the bases of some high-end ergonomic chairs support forward tilting (such as the domestic Baoyou Jinhao e and the foreign Herman Miller Aeron), which are mainly more friendly to people who work at desks. If the seat cushion is tilted forward, the front end of the cushion can be placed on top. Leg numbness caused by prolonged sitting.
(4) The armrest is mainly to provide a support for the arm. The adjustability of the armrest is relatively less important than the above ones. As long as there is the most basic up and down adjustment, the other functions are icing on the cake. It doesn't matter if you don't have them. Some manufacturers work hard on armrest adjustment. I personally think it is of little significance. Their purpose is just to increase the selling price. The current armrest adjustments include: 6D>5D>4D>3D>2D>1D>Fixed>No armrests
6D: Supports up and down, front and back, left and right rotation, left and right translation, upward tilting, and linkage adjustment
5D: supports up and down, front and back, left and right rotation, left and right translation, and linkage adjustment
4D: supports up and down, front and back, left and right rotation, and linkage adjustment
3D: supports up and down, front and back, left and right rotation adjustment
2D: supports up and down, front and back adjustment
1D: supports up and down adjustment
When I talk about linkage, I mean that when the back of the chair is tilted back, the armrests will tilt simultaneously. This is helpful for leaning back while playing with the phone and can give me arm support.
2. Look at the material
The material is divided into two aspects, one is the chair surface (headrest, chair back, seat cushion), and the other is the chair legs.
The chair surface is mainly divided into two types: mesh surface and sponge
Mesh: Good breathability, but limited load-bearing. Imported mesh is more durable than domestic mesh, such as American Matrex, Korean Wintex, DuPont mesh, flocking mesh, etc.
Sponge: better load-bearing and durable, suitable for people with heavy weight, but not breathable.
The material of the chair legs is divided into aluminum alloy, nylon and steel. Among them, aluminum alloy has the best load-bearing capacity, nylon is lighter, and steel is purely for a better appearance. It cannot be said that it is not good. It mainly depends on the price. You get what you pay for.
3. Look at your body shape
Regarding body shape, this is mainly for small bodies (below 155cm) and large bodies (above 185cm or more than 90kg)
Most chairs on the market are designed for the average body size, which is 160-185cm and weighing less than 80kg. For this kind of people, buying chairs basically doesn't have a big problem.
(1) Below 155cm
There are not many ergonomic chairs on the market that are suitable for teenagers with small bodies. You can choose the one specially designed for small bodies. If the chair surface is too large and you only sit on half of the chair surface each time, then the waist of the ergonomic chair Support is decoration.
(2) 185cm or more
There are actually quite a few to choose from, but be careful with some chairs. The headrest or backrest may not be high enough and may get stuck on your shoulders. In addition, tall people must choose chairs with seat depth adjustment and backrest height adjustment. Yes, the adaptability will be better.
(3) More than 90kg
It is recommended that overweight people avoid choosing high-rebound mesh chairs. First of all, for overweight people, the high-rebound mesh is relatively soft, which will have a greater impact on the life of the mesh. Secondly, if it is too soft, you will sink when you sit on it. When you get in, your thighs will be hugged, which is not particularly comfortable. If you sit for a long time, you may experience numbness in your legs (the front end of the cushion will press against your thighs, compressing the blood vessels and nerves in your legs for a long time, which will cause numbness in your legs). .
For this group of people, you can choose the kind of low-elastic mesh that is harder, or choose a sponge cushion.
