office chair mechanism
The office chair mechanism serves as the core control unit of the chair, dictating its adjustability and ergonomic performance to match diverse sitting postures and work scenarios.
• Ergonomic Adjustment: Supports multi-dimensional adjustments including 360° smooth swivel for free movement, gas lift height adjustment (typically 10-15cm range) to fit different desk heights, and recline tension control—turn the knob to customize the resistance when leaning back, adapting to users of varying weights (50-120kg).
• Structural Reliability: Crafted from high-grade cold-rolled steel or aluminum alloy, it features a precision-machined gear system and anti-wear nylon components. The load-bearing capacity reaches 150-200kg, with a service life of over 50,000 adjustment cycles, ensuring long-term stability without looseness or jamming.
• Safety & Comfort: Equipped with a locking function (e.g., 3-position tilt lock) to fix the backrest at specific angles (90° for focused work, 110°-135° for relaxation). The mechanism operates silently (≤30dB) to avoid disrupting the work environment, while its compact design seamlessly integrates with the chair frame for a sleek overall look.
