Office Chair Base Types

Admin October 14, 2026

Office chair bases mainly include types such as caster bases, fixed bases, pneumatic bases, single-spring lever-controlled bases, self-weight lever-controlled bases, butterfly bases, gravity-sensing bases, fiberglass bases, and space bases.

Caster bases are equipped with casters at the bottom of the office chair. This design greatly facilitates the movement and repositioning of the chair. Whether frequently changing work positions in an open office environment or moving between different areas, caster bases can handle it with ease, suitable for various floor conditions, especially ideal for office scenarios that require frequent adjustments.

Fixed bases do not have mobility; their design focuses on providing more stable support. Without the interference of casters, the chair can be firmly fixed in place, offering strong support to the user. They are typically used in situations where prolonged sitting is required, such as conference rooms or offices, ensuring that users are not distracted by chair wobbling while focusing on their work.

Pneumatic bases combine comfort and adjustability. With a pneumatic rod, the height of the chair can be easily adjusted to meet the needs of different users and various work scenarios. They are commonly used in high-end office chairs, suitable for office environments that require height adjustability and comfort, such as high-end desks or conference chairs, allowing users to find the most comfortable height according to their physical condition and work habits.

Single-spring lever-controlled bases control operations such as recline locking and height adjustment through a single lever. The recline force can be adjusted via a knob, but the recline force may not be uniform.

Self-weight lever-controlled bases are double-spring bases with independent designs, offering more functional adjustments and improving the issue of recline resistance, but not truly solving it from the source.

Butterfly bases are characterized by large knobs on the gravity base. The knobs can be turned to adjust the recline support force, allowing users to make flexible adjustments according to their own needs.

Gravity-sensing bases change the spring travel through gravity. The force required for different weights of people to recline varies, but there may be situations where the recline resistance is inappropriate for those who are too light or too heavy.

Fiberglass bases, such as the fiberglass base from Ergohuman, do not shift and do not cause the waist to move, providing more stable waist support for users.

Space bases, such as the space base from Sihoo, use special high-performance fiberglass materials to achieve precise adjustment of the recline force, allowing people of different weights to recline without pressure and get up easily.
