What Is The Biggest Difference Between An Ergonomic Chair And An Ordinary Office Chair

1. Dimension
Ordinary office chairs usually only provide one size, and because the height and width of different office chairs are different, what body shape can be suitable for should be determined according to the size of relevant products. In contrast, ergonomic chairs have multiple adjustment functions, so they are more suitable for a wider range of human body sizes. Some ergonomic chairs provide multiple sizes for selection, such as Herman Miller's Aeron, but not all ergonomic chairs can meet all human body sizes. For example, the Diffrient World ergonomic chair under Humanscale is not suitable for tall and fat people.

2. Structure

head pillow:
It can be found that many ergonomic chairs do not have headrests. Why? The function of the head restraint is nothing more than to support the head when it is tilted backward during rest, while the function of the head restraint is basically zero when it is working in a normal sitting posture. Therefore, whether there is headrest is not the key to an ergonomic chair, but it is better than nothing. The headrest comfort can be regarded as a model, which is the Freedom series ergonomic chair under Humanscale. The details will be explained below.

back:
The back of the chair can be said to be the soul of the whole ergonomic chair, which is also the key difference from the ordinary office chair. It is not a simple curve that can solve the problem. The material used, the fit with the human spine, and the tilt adjustment method are all the keys to the back of the chair. A good back should give people a relaxed feeling, without oppression, weight bearing and stuffiness.

Lumbar support:
Most ergonomic chairs will have an adjustable lumbar support, and of course, some do not. Adjustable lumbar support can be divided into up and down adjustment, left and right adjustment, strength adjustment or asymmetric strength adjustment. The adjustment mode is not the most important, but the important thing is whether lumbar support+seat back can provide perfect support for the spine and lumbar spine.

Cushion:
The seat feel varies greatly with different materials. The main categories mentioned above will not be repeated here. The "high-end" ergonomic chair is made of patented materials, so the sitting feeling is very different. In addition to the material of the cushion, the ergonomic chair is very different from the ordinary office chair in the shape design and adjustment mode of the cushion. In order to reduce the pressure on the nerves and blood vessels of the hips and legs, the front end of the ergonomic chair cushion is usually waterfall shaped, Secondly, the seat depth adjustment can be divided into fore and aft adjustment (not changing the length of the seat cushion, but changing the distance from the seat back) and curling adjustment (not changing the distance from the seat back, but changing the length of the seat cushion). Leap and Gesture under Shikai adopt fore and aft adjustment, while Body and Mira2 under Herman Miller adopt curling adjustment.

Handrail:
Whether the armrests are connected with the back of the chair is related to the overall comfort of the entire ergonomic chair. Only when they are connected, can the armrests maintain the same angle with the back of the human body when reclining, so that the arms can be comfortably supported. At the same time, it is also important to adjust the armrest from front to back, left to right, up and down. Herman Miller recently launched a new ergonomic chair, named "Cosm". Whether the original blade armrest can become a classic will be answered after the official sale.

Chair legs:
The chair legs of ergonomic chairs usually use five star legs, while ordinary office chairs use four foot, bow foot, etc. in addition to five star legs. There are three main materials for the chair legs: nylon, steel and aluminum alloy. Strength: aluminum alloy>steel>nylon. As far as the weight of human body is concerned, the nylon chair legs are enough to bear.

Air bar:
The reason for the explosion of the office chair is the use of inferior air pressure rods. Well known brands of air pressure bar include Korean KGS, South Korea Sanhong SHS, etc. I found that most of the big ergonomic chairs use air pressure bars from South Korea Sanhong. As long as other brands of air pressure rods have passed the quality certification, the safety is basically no problem.

Chair wheel:
Most ordinary office chairs use hard wheels, while ergonomic chairs usually have two kinds of chair wheels (hard wheels and soft wheels) to choose from. The hard wheels are suitable for carpets, while the soft wheels are suitable for wood floors and porcelain floors.
