High Back Mesh Office Chair - Ergonomic Computer Chair with 4D Armrests, 360° Swivel & Adjustable Recline (90°-120°), Breathable Mesh Back for Home/Office (300 lb Capacity)

Advanced 4D Armrest System: Features fully adjustable armrests that pivot 90° upward for space-saving storage and rotate 30° for optimal forearm positioning. Height-adjustable with horizontal movement to accommodate different desk heights and body types, reducing shoulder strain during extended computer use. Dynamic Reclining Mechanism: Smoothly adjusts between 90° (upright working position), 105° (relaxed leaning), and 120° (resting recline) with easy-to-reach handle control. The tension-adjustable tilt mechanism provides personalized resistance to match your preferred sitting style and body weight. Premium Ventilated Design: High-elasticity mesh backrest promotes constant airflow to prevent heat buildup. The dual-layer mesh fabric maintains structural integrity while flexing with your movements, offering both support and breathability during long sitting sessions. Engineered Comfort Seating: W-shaped seat cushion contours to your body with high-resiliency foam that won't flatten over time. The waterfall edge design (24.8"W × 26.6"D) improves leg circulation while the slightly concave center keeps you properly positioned (height adjustable). Commercial-Grade Mobility: Heavy-duty nylon base with 360° swivel and smooth-rolling dual-wheel casters. The industrial-strength Class-4 gas lift provides stable height adjustment while supporting up to 300 lbs, making it suitable for diverse office environments and user sizes.
