Nowadays, many people generally pay attention to the appearance, function and price of office chairs when choosing office chairs. Those who know how to do it know that the core technology of office chairs lies in the design of the chassis. A good chassis can make people better operate and adjust the office chair. As long as you grasp this point, the office chair you choose will be very comfortable and safe.
At present, the mainstream office chair chassis types on the market are roughly divided into three types: one is a conventional three-function chassis, which is relatively ordinary and has a relatively large market share. This type of chassis has two control devices, a lift control lever and a knob. The office chair has three basic functions: locking, lifting, and adjusting the weight of the back elasticity of the office chair. The operation is also very simple. The right lever is the condition to control the back of the chair. Pushing in is to lock the back of the chair. Pull out to release the lock of the back of the chair. You can press on the back to adjust the angle of the back of the chair; It is to adjust the lifting height of the office chair by turning the control lever clockwise.
The other is the engineering four-function chassis. Compared with the conventional three-function chassis, it has two obvious characteristics. One is that the chassis uses wire control technology, which avoids the control device that directly extends from the internal structure like the conventional chassis. Make the control position more concentrated and beautiful. The second is to increase the front and rear adjustment and depth adjustment of the seat, so that the office chair can adapt to customers of different heights. This design gives the user a more intuitive feeling and a more comfortable sitting. The depth adjustment of the seat is one of the main differences between ordinary office chairs and engineering office chairs.
Finally, there is a five-function chassis for engineering. In addition to the above four functions, this chassis has added seat cushion angle adjustment to meet the needs of different users from more aspects. The chassis is designed to closely integrate the chassis and the seat, so the office chair manufacturer has already assembled the chassis, seat, and back of the chair. After purchasing, customers only need to install the air rod and the chair caster wheel.
Different office chair manufacturers are using conventional three-function chassis and engineering four-function chassis. The conventional chassis is the market demand, and the engineering chassis is the customer demand.
