What is the difference between an ergonomic chair and an ordinary office chair?
The biggest difference between ergonomic chairs and ordinary office chairs is that they can more satisfy people's comfortable sitting, which is mainly reflected in the following aspects:
1. Size
Ordinary office chairs usually only provide one size, and since the chair height and width of different office chairs are inconsistent, what kind of human body shape can be suitable should be determined according to the size of the related products. In contrast, ergonomic chairs have a variety of adjustment functions, so they are suitable for a wider range of human body shapes, and some ergonomic chairs will provide multiple sizes to choose from, such as Ivyco's NOBLE, but not all ergonomic chairs. The chairs can meet all body types, such as the 830 series ergonomic chairs from Ivyco, which are not suitable for tall and fat people to sit on.
2. Structural aspects
Headrest:
It can be found that many ergonomic chairs do not have headrests, why? The function of the headrest is nothing more than to support the head when resting and leaning back, while the function of the headrest is basically zero in the normal working posture. So it's not critical for an ergonomic chair to have a headrest, but it's better than none. The comfort of the headrest is exemplary of the NOBLE series of ergonomic chairs owned by Ivyco, which will be explained below.
Chair back:
The back of the chair can be said to be the soul of the entire ergonomic chair. This is also the most critical point that differentiates it from ordinary office chairs. It is not a problem that can be solved by a simple curve. The materials used and the fit of the human spine The key to the back of the chair is to adjust the way of tilting and tilting. A good chair back should feel relaxed and comfortable, without pressure, weight and stuffiness.
Lumbar support:
Most ergonomic chairs come with an adjustable lumbar support, although some do not. Adjustable waist support is divided into up and down adjustment, left and right adjustment, strength adjustment or asymmetric strength adjustment. The adjustment method is not the most important, the important thing is whether the lumbar support + chair back can perfectly support the spine and lumbar spine.
cushion:
Different materials, the seat's sitting feeling is quite different, the main classification has been mentioned above, and will not be repeated here. "High-end" ergonomic chairs are mostly made of patented materials, so the seated feeling is even more different. In addition to the material of the seat cushion, the ergonomic chair is very different from the ordinary office chair in the shape design and adjustment method of the seat cushion. The front end is usually waterfall-shaped, and then the seat depth adjustment can be divided into front and rear adjustment (do not change the length of the seat cushion, change the distance from the seat back) and curl adjustment (do not change the distance from the seat back, change the length of the seat cushion), Ivyco Its NOBLE, etc. use front and rear adjustment.
armrest:
Whether the armrest is connected with the back of the chair is related to the overall comfort of the entire ergonomic chair. Only when they are connected together, can the armrest maintain the same angle as the back of the human body when leaning back, so that the arm can be comfortably supported. At the same time, it is also important to adjust the front, rear, left, right, up and down adjustment of the armrest.
Chair legs:
The legs of ergonomic chairs usually use five-star feet, while ordinary office chairs also use four-legged, arched feet, etc. in addition to five-star feet. There are three main materials for the legs of the chair: nylon, steel, and aluminum alloy. Strength size: aluminum alloy>steel>nylon. As far as the weight of the human body is concerned, the nylon legs are enough to bear.
Air bar:
The reason for the explosion of the office chair is the use of inferior air pressure rods. The more well-known brands of air pressure rods are: Korea KGS, Korea Sanhong SHS, etc. As far as I found, the big-name ergonomic chairs mostly use the air pressure rods of Korea Samhong. As long as other brands of pneumatic rods are certified for quality, there is basically no problem with safety.
Wheels:
Most ordinary office chairs use hard wheels, while ergonomic chairs usually have two types of wheel (hard wheels and soft wheels) to choose from. Hard wheels are suitable for carpets, and soft wheels are suitable for wood floors and porcelain. floor.
If you want to buy a "high-end" computer office chair - ergonomic chair, you need to know the brand of ergonomic chair and the famous series of ergonomic chair products on the market, and then it is best to go to the stores of these brands to experience, after all, a mid-to-high end None of the ergonomic chairs are cheap.
