Metal Fixed Office Chair
Metal fixed office chairs primarily feature steel frame structures or all-metal frames. Common types include steel frame office chairs, metal-structured ergonomic chairs, and auditorium chairs. Among them, auditorium chairs are a typical fixed design, while other types are mostly movable but can achieve partial fixation through structural adjustments.

1. Steel Frame Office Chairs: Basic Sturdy Fixed Design
Some steel frame office chairs use thickened one-piece bent steel frames or electroplated steel frames, such as the simple armrest reception chair (ยฅ66.0) and the thickened electroplated steel frame mesh conference chair (ยฅ63.0). Their core features include:
- Structural Fixity: The steel frame is fixed to the seat and backrest through welding or bolts, forming an integral structure that cannot be disassembled, ensuring long-term use without deformation.
- Application Scenarios: Primarily used in office buildings, conference rooms, and other settings that require long-term stable placement, emphasizing sturdiness and durability.
- Mobility Limitations: They come with casters by default, but partial fixation can be achieved by replacing them with fixed foot pads or locking the casters, though they are not originally designed as fixed chairs.
2. Ergonomic Chairs: Dynamic Fixation Supported by Metal Frames
High-end ergonomic chairs achieve structural fixation and functional dynamic balance through metal frames, for example:
- ENOVA Alloy Master: It adopts a full aluminum alloy frame (back frame, armrest connectors), paired with an Italian DONATI base that supports resistance adjustment for reclining and dynamic lumbar support functions. Its metal frame is fixed, but the base adjustment allows for dynamic sitting posture adaptation, suitable for prolonged office sitting.
- Sihoo C300 Second Generation Pro: It relies on a metal skeleton to support DynaCore mesh and a domino lumbar support system. Although not explicitly labeled as 'fixed', the metal structure ensures the relative fixity of components such as the backrest and armrests, while the elastic mesh allows for full-posture adaptation.
3. Auditorium Chairs: Typical Fixed Metal Seating
Auditorium chairs are representative of metal fixed office chairs, with design features including:
- All-Metal Brackets: Made of rust-resistant metal materials (such as steel pipes), they are fixed to the ground through single-leg landing or armrest stands, non-movable.
- Ergonomic Standards: With a seat height of 400-440mm and a back height of 1020mm, they meet the needs of prolonged use in public spaces.
- Application Scenarios: Specifically designed for auditoriums, conference rooms, theaters, etc., emphasizing space utilization and user comfort.
4. Differentiation Between Fixed and Movable Chairs
- Fixed: Such as auditorium chairs, they are directly fixed to the ground through metal brackets, without casters or movable parts.
- Movable: Most steel frame office chairs come with casters by default, but partial fixation can be achieved through structural adjustments (such as locking the casters); ergonomic chairs, although their metal frames are fixed, are still movable as a whole.
