The Mid-Back Mesh Swivel Office Task Chair, model TASK-MESH-GRY-01, delivers understated, functional seating with a coordinated neutral light grey finish that blends seamlessly across professional and residential work environments. Its visual profile features a streamlined mid-back structure, fixed loop armrests, and a five-prong caster base, creating a balanced, unobtrusive silhouette that avoids overly bulky detailing to support open, uncluttered space layouts. Constructed for consistent long-term use, the chair pairs a tensioned breathable grey polyester mesh back with an integrated curved ribbed lumbar support, paired with a seat built from a molded high-resilience polyurethane foam pad upholstered in woven grey fabric. The frame and fixed armrests use glass-filled nylon with a matte light grey finish, supported by a 2.0mm thick welded steel internal seat plate, 14mm bent plywood seat support board, 50mm diameter Class 3 chrome-plated steel gas lift, and 1.8mm thick steel butterfly tilt chassis. The glass-filled nylon five-star base is fitted with 50mm dual-wheel hard-floor nylon casters, two of which include integrated brake tabs. The seat cushion uses 45 kg/m³ density foam with 65% rebound, with a total finished cushion thickness of 90mm; the backrest features 70mm padding and a 240mm tall lumbar support zone, with 540mm of clear width between armrests. The mesh back delivers 30,000 Martindale cycles of abrasion resistance, the gas lift supports a 150kg static load, and the five-star base holds a 1136kg static load capacity, with a net product weight of 12kg. Core practical functions support flexible seated work: the seat offers 100mm of vertical height adjustment via an under-seat lever, 360-degree continuous swivel rotation, and 12-degree synchronized backward tilt that reaches a 125-degree recline with three suggested lock positions controlled by a single locking lever. The fixed integrated lumbar structure provides consistent mid-back support, while the fixed-height loop armrests position forearm support appropriately for typing tasks. Two casters include locking tabs to hold the chair stationary when needed. This chair is suited for 8-hour daily seated task work at standard 760mm height desks, fitting users up to 185cm tall. It works equally well for open office workstations, home office setups where its neutral finish complements modern residential desks, high-turnover shared training rooms, and collaborative conference spaces. It is recommended for pairing with 2.4m executive desks. For procurement, note that each unit ships as one set across two cartons, with a packaged gross weight of 23kg per set and total carton volume of 0.26 m³. Assembly takes 40 minutes per set, and a 20GP container holds 135 sets at 85% space utilization. The product is offered as an unbranded model, with swivel function, height adjustability, five-star base, mid-back support, and included armrests as core standardized features.
