Product Description

The Black Mesh Ergonomic Swivel Task Chair is a mid-back office seating solution with a neutral all-black appearance suited to shared and individual work environments. Its visual character is defined by a flexible black polymer mesh back set within a contoured molded nylon frame, paired with a black woven fabric seat, fixed arm supports, and a black five-star base. A visible lumbar opening gives the backrest a structured ergonomic profile, while the swivel seat and caster base reinforce its functional task-chair form. Overall dimensions are 650 by 650 by 1060 millimeters, with 540 millimeters of clear width between the armrests. The seat cushion uses 65 millimeters of molded foam beneath its fabric upholstery, and the listed finished cushion thickness is 90 millimeters. The backrest includes 70 millimeters of padding thickness and a lumbar support zone height of 240 millimeters. Construction combines molded foam, fabric, mesh, nylon frame and base components, a steel gas lift, and twin-wheel casters. The internal seat structure is a molded plywood or reinforced polymer seat shell, while the arm supports and back frame are injection-molded black nylon. The lift column is a black-coated steel telescoping tube with a chrome upper section, and the molded nylon base includes integral hub reinforcement. Practical adjustment is centered on daily desk use. A pneumatic lever controls seat height through a 100 millimeter class-3 gas-lift stroke. The synchro-tilt mechanism moves the back and seat together, with four lock positions across 19 degrees of recline, and a rear rotary knob adjusts tilt resistance. The chair also provides 360-degree swivel movement and five twin-wheel casters for mobility on hard floors and low-pile carpet. Fixed armrests offer consistent upper-body support during computer work, meetings, and workstation transitions. The chair is appropriate for open-plan offices, private offices, meeting rooms, shared workstations, hot desks, and training positions. Its black finish supports a broad range of interiors, and its swivel and recline functions suit short-to-medium duration meetings as well as regular desk tasks. The model is unbranded and identified as TASK-MIDBK-AR-01. Procurement teams should plan for assembly, with a reference time of 40 minutes per set, and note that the product is supplied as one set across two cartons with a packaged gross weight of 23 kilograms. The rated user weight is 120 kilograms, net weight is 14 kilograms, and seat foam density is 45 kilograms per cubic meter. Buyers specifying larger fleets should also review delivery access, storage space, assembly responsibility, replacement or warranty terms, and compatibility with the intended floor type and work surface height.
