Budou Office Chair Structure

“Budou” is not a clearly defined type or brand of office chair. Its structure may be adjusted or combined based on common office chair structures, but without specific information, its unique structure cannot be clearly identified. The following is an introduction to common office chair structures:

Backrest Section

Mesh-back office chairs are a common type, using mesh as the main supporting surface. The mesh has good elasticity, and its tension is fixed by a nylon frame, forming a supporting surface with a certain degree of elasticity. This design can conform to the curve of the human back. When a person sits on the chair, the back makes full contact with the backrest, and the mesh can deform according to the shape of the back, thereby dispersing the pressure on the back, providing comfortable support, and reducing fatigue caused by prolonged sitting.

Seat Cushion Section

The seat cushion is usually composed of a wooden board, sponge, and fabric. The wooden board serves as the basic supporting structure, providing a stable bearing platform for the seat cushion. The sponge is a key factor affecting the comfort of the seat cushion, and there are two types: recycled sponge and new sponge. Recycled sponge has a lower cost but relatively poor elasticity and durability; new sponge has better elasticity and resilience, providing more long-lasting comfortable support. There are various types of fabrics, including hemp, mesh, and leather. Hemp fabric has good air permeability and is suitable for use in warm environments; mesh fabric is similar to the backrest mesh, with good air permeability and elasticity; leather fabric appears high-end and is easy to clean, but has relatively poor air permeability.

Chair Legs and Casters Section

Chair legs are important components that support the entire office chair, and they can be made of materials such as nylon and steel. Nylon chair legs are lightweight and low-cost but have relatively weak load-bearing capacity; steel chair legs are sturdy and durable with strong load-bearing capacity but are heavier. In terms of casters, there are ordinary casters and PU casters. Ordinary casters are suitable for general floors, while PU casters have better noise reduction and wear resistance, cause less damage to the floor, and are more suitable for use on delicate floors such as wooden floors.

Other Sections

The chassis is a key component that connects the seat cushion and the chair legs, responsible for functions such as adjusting the seat height and tilt angle. The pneumatic rod is the core component for adjusting the seat height, achieving smooth lifting and lowering through the principle of air pressure. The dust cover is used to protect internal structures such as the pneumatic rod, preventing dust from entering and affecting the service life.
