The unbranded mid-back grey mesh ergonomic office task chair, model MB-GR-MESH-01, delivers balanced, functional seating for diverse work settings with a clean, coordinated matte grey finish that integrates seamlessly with professional and casual workspace aesthetics. Its structured silhouette features a tensioned grey mesh backrest contoured to deliver built-in mid-lumbar support, paired with a padded fabric seat, integrated fixed loop armrests, and a wide five-star base fitted with smooth-rolling casters, creating a streamlined profile that fits neatly under standard desk surfaces without overcrowding surrounding floor space. Built for consistent long-term use, the chair combines durable, purpose-selected components: a glass-fiber reinforced polypropylene frame supports the breathable mesh back, which is rated for 50000 Martindale abrasion cycles. The seat uses a 60mm thick, 40kg/m³ high-density molded polyurethane foam core with a CA117 fire-retardant rating, supported by a 12mm plywood base plate and upholstered in abrasion-resistant grey woven fabric. Fixed fiber-reinforced polypropylene armrests sit 210mm above the seat surface, while a reinforced nylon five-star base with a 640mm diameter supports a Class 3 black powder-coated steel gas lift, 2.5mm thick steel butterfly tilt plate, and 60mm dual-wheel polyurethane casters tested to 40000 rolling cycles. The chair holds a maximum recommended user weight capacity of 136kg, with a net weight of 12.7kg. Core functional features include 100mm of pneumatic seat height adjustment controlled via a side lever for a maximum seat height of 540mm from the floor, 360-degree swivel, synchronized back recline with user-adjustable tension, one lockable recline position, weight-activated tilt resistance that automatically calibrates to the user, and caster mobility suited for hard floors and low-pile carpet. The breathable mesh back eliminates heat buildup during extended seated sessions. This chair is suitable for open office workstations paired with standard 760mm height desks, compact home office setups, meeting room task seating, study or casual computer use stations, high-turnover coworking shared spaces, and administrative workstations, where its height range accommodates users up to 185cm tall. Procurement teams should note each unit ships across two cartons, requires 40 minutes of assembly per set, and supports efficient bulk shipping, with 135 sets fitting a 20GP container at 85% space utilization. Overall dimensions measure 640mm wide, 620mm deep, and 1130mm tall, with a 510mm wide, 415mm deep seat and 670mm tall backrest. It carries no third-party sustainability or safety certifications beyond the noted CA117 foam fire rating, so buyers should confirm alignment with organizational furnishing standards prior to purchase.
