Product Description

This mid-back office task chair features a streamlined, professional silhouette defined by a matte black upholstered seat and back paired with reflective polished chrome structural elements. Its five-star base sits below a central support column, with fixed cantilever armrests positioned at consistent height on either side of the seat, creating a balanced, uncluttered layout that complements both formal and casual work environments.
The chair is constructed for consistent long-term use, with a 1.0mm thick black PU faux leather upholstery covering seat and back sections filled with high-density polyurethane foam. Its inner support frame uses welded steel tubing, paired with a chrome-plated solid steel armrest structure, a Class 3 chrome-plated steel pneumatic lift cylinder, a steel plate tilt mechanism with spring assembly, and a polished chrome-plated die-cast aluminum five-star base. All metal components feature a mirror chrome finish with anti-corrosion treatment, and black nylon dual-wheel casters mount to each point of the base for smooth movement.
Functional features support productive seated work: a right-side under-seat lever controls 100mm of pneumatic vertical seat height adjustment, while the full 360-degree swivel allows easy access to surrounding work surfaces without repositioning the base. The spring-loaded tilt mechanism enables a 15-degree backward recline with adjustable tension control, plus a lock to hold the chair in a fully upright position for focused task work. The two-section padded backrest delivers targeted mid-back support for aligned lumbar positioning, and the rigid fixed armrests provide steady elbow support throughout the workday. The dual-wheel casters enable low-noise movement suitable for hard flooring surfaces including tile, wood, and laminate, with a recommended user weight capacity of 125kg.
This chair suits a wide range of spaces. It is appropriate for open office workstations supporting daily 8-hour seated work at standard-height desks, and its minimalist black and chrome aesthetic integrates smoothly into conference and meeting room layouts. Its compact footprint makes it a practical choice for residential home office setups where bulk must be minimized, while its polished finish works well for front-of-house executive guest or visitor seating. Its durable construction also supports high-turnover commercial office installations.
For procurement planning, note that each unit ships in two cartons, with an assembly time of 40 minutes per set. The upholstery holds up to 50,000 double rubs of abrasion resistance, supporting frequent use in high-traffic settings, and shipments can be planned to accommodate container loading for large-scale project orders.
