Office Chair with Fixed Feature

The following office chairs can be fixed or have fixed-related features:

1. High-back Mesh Staff Office Chair
   This model is explicitly labeled as a 'Fixed Armrest Leisure Conference Chair'. From its naming and functional description, it can be inferred that it has a fixed structure. Designed for conference settings, it typically requires maintaining a stable posture. Therefore, the armrests and chair body may adopt an integrated fixed design to avoid movement interference. Additionally, the 'leisure' function may refer to the chair back being able to tilt slightly backward for adjustment, but overall, it is primarily fixed, suitable for office or conference scenarios where a long-term sitting posture is required.

2. Bow-shaped Mesh Office Chair
   The typical feature of a bow-shaped chair is that its legs form an arc-shaped bow structure, directly contacting the ground with no caster design. This structure provides support through bow-shaped elasticity and naturally possesses fixity, maintaining stability without the need for additional locking devices. Its advantages lie in its simple structure, low cost, and avoidance of movement risks that casters may cause, making it suitable for office environments requiring a fixed sitting posture, such as drawing or writing focused work.

3. Fixed-leg Computer Chair
   This model is directly named 'Fixed-leg', and its functional description emphasizes 'both sitting and lying functions', but explicitly excludes caster design. Its fixity may be achieved in two ways: first, the bottom of the chair legs may use anti-slip rubber pads or weighting design to enhance friction with the ground; second, the chair body structure may be integrated with the base, with no rotating or moving parts. Such chairs are suitable for scenarios requiring frequent switching between sitting and lying postures, such as lunch breaks or short rests, where the fixed design can avoid safety hazards caused by casters.

Analysis of Other Models:
The installation instructions for the 1012A and 1033A office chairs include steps for installing base casters, indicating that they support mobility by default and do not mention fixed design; the remaining models are mostly labeled as 'height-adjustable rotating casters' or 'swivel chairs', all with mobility as their core selling point. If fixed functionality is required, it is recommended to prioritize the above-mentioned models explicitly labeled with fixed features and confirm whether the product details page includes key descriptions such as anti-slip, weighting, or no casters.
