Product Description

The TASK-MESH-GRB-01 is an unbranded ergonomic office task chair distinguished by a green mesh back, black woven-fabric seat, and black molded polymer frame. Its medium-height back combines a flexible geometric-weave mesh panel with a green padded horizontal lumbar band, creating a breathable support surface with a clear visual accent against the black seat, armrests, and five-star base. The contoured seat uses molded polyurethane foam with a waterfall front and is carried by a molded plywood or polymer inner support. Fixed black T-armrests sit between the user and the work surface, while twin-wheel casters complete the mobile task-chair form. Overall dimensions are 660 by 640 by 1040 millimeters, with 540 millimeters of clear width between the armrests and a 90-millimeter finished cushion. Construction centers on a black steel gas lift with a telescopic polymer sleeve, injection-molded nylon arm supports and underside brackets, a polymer perimeter frame, and polyurethane casters. The seat upholstery is black woven fabric over an 80-millimeter molded foam cushion specified at 38 kilograms per cubic meter. The padded lumbar band and 70-millimeter backrest padding zone provide structured contact, while the chair has a recommended user weight capacity of 136 kilograms and a net weight of 15 kilograms. Functionally, the pneumatic lift offers 100 millimeters of seat-height travel, from 440 to 540 millimeters. The seat rotates 360 degrees for multi-directional access, and the synchronized tilt mechanism provides 12 degrees of back recline with one-position tension control. Fixed armrests place the matte T-pads 230 millimeters above the seat for forearm support, and the rounded waterfall edge is intended to reduce pressure concentration behind the knees. The five twin-wheel casters support movement on hard floors and low-pile carpet. This model is suited to open-plan offices, shared workstations, home offices, meeting rooms, computer rooms, hot-desking areas, administrative workspaces, and small professional studios. It is especially relevant where rotating users need adjustable seat height, rolling access, lumbar contact, and support for keyboard, phone, or document tasks. The green back offers color differentiation, while the black seat is intended to conceal regular use marks. Procurement teams should note that each set ships in two cartons, with packaged gross weight of 23 kilograms and reference assembly time of 40 minutes. Buyers should also confirm seat-height compatibility with intended desks; the documented home-workstation reference is a 760-millimeter work surface for users requiring the 540-millimeter seat height.
