Office Chair Base Types
There are various types of office chair bases, with the following being the common ones:
Regular Three-Function Base: This is a relatively basic type of base equipped with two control devices: a lever and a knob. It has three basic adjustment functions: backrest lock, seat cushion height adjustment, and backrest recline tension adjustment, which can meet users' basic sitting posture adjustment needs. The backrest recline angle is approximately between 125 - 130ยฐ, making it suitable for daily office scenarios.
Ergonomic Four-Function Base: Represented by the base of the Daboli D1 flagship ergonomic computer chair. It adopts wire control technology, solving the problem of scattered and unattractive control devices. On top of the original functions, it adds a seat cushion forward-and-backward adjustment function, further enhancing the comfort and adaptability of the chair. The backrest recline angle is approximately between 130 - 135ยฐ, and there are various operation methods such as buttons, levers, and dials, allowing users to operate according to their own habits.
Ergonomic Five-Function Base: Such as the base of the Jinhao + L ergonomic computer chair sold by Daboli. In addition to the four adjustment functions of the ergonomic four-function base, it also adds a seat cushion angle adjustment function. Moreover, the base, seat cushion, and backrest are pre-assembled during factory production, making installation easy and saving users installation time and effort.
Self-Weight Four-Function Base: Taking the Italian DONATI self-weight four-function base of the Daboli DY205 ergonomic computer chair as an example, it upgrades the backrest recline tension adjustment function from manual to automatic, automatically adjusting the recline tension according to the user's weight, making it more convenient to use.
Single-Spring Lever-Controlled Base: It controls backrest lock, height adjustment, and other operations through a single lever and adjusts the recline force through a knob. However, the recline force of this base is not uniform enough, which may affect the user's experience.
Self-Weight Lever-Controlled Base: Essentially, it is a dual-spring base with independent design, providing more function adjustments and improving the backrest resistance problem, but it fails to solve it from the root.
6th Generation Space Base: Developed by Sihoo, it uses special high-performance glass fiber materials and makes five major breakthroughs in angle, material, mechanics, mechanism, and touch. Combined with a spring-plate mechanical design, it can achieve precise adjustment of the backrest recline force, providing users with a more comfortable sitting experience.
Carbon-Glass Fiber Base: For example, the carbon-glass fiber base used in the Sihoo c500 ergonomic chair has undergone 300,000 tests and can achieve infinite suspension. Moreover, the adjustment adopts an integrated wire control design, making operation more convenient and precise.
