Product Description

The Mid-Back Grey Mesh Ergonomic Task Chair with Height-Adjustable Arms is a practical seating solution for task-focused workspaces. Its grey woven mesh and light-grey polymer components create a clean, coordinated appearance, while the five-star base, twin-wheel casters, and contoured back give it a recognizable office-task profile. The model EM-GMESH-ADARM-01 is offered unbranded and fits within the ergonomic office chair category for commercial or residential specification. Visually, the chair uses grey flexible mesh across the back and seat, supported by polymer perimeter and seat-pan structures. A curved, mesh-covered polymer lumbar cushion defines the lower-back zone, and light-grey arm posts complement the frame. The under-seat tilt plate and lift linkage are made from black steel and enclosed by a light-grey polymer housing, balancing an open mesh look with structured support. The light-grey molded five-star base is fitted with black twin-wheel casters. Construction combines breathable mesh, molded polymer, steel under-seat hardware, a gas lift, and a foam-free suspension seat. The finished seat cushion thickness is 90 mm, backrest padding thickness is 70 mm, and the lumbar support zone height is 240 mm. The clear width between armrests is 540 mm. Overall dimensions are 670 x 670 x 1090 mm, and the chair weighs 17.5 kg. Buyers should note that the base may be supplied as painted metal or nylon according to the stated product configuration. Functionality is centered on adjustable ergonomic task support. A pneumatic lever adjusts seat height from 430 to 530 mm through a Class 4 gas lift with a 100 mm stroke. The synchro-tilt mechanism allows 18 degrees of controlled backward travel with multi-position lockout. Height-adjustable arm pads move through 80 mm and align beside the front edge of the seat. A 360-degree swivel and five casters support movement on hard or carpeted office floors. The stated maximum user weight is 136 kg. The chair is suited to open-plan office workstations, conference rooms, study rooms, and home offices, especially where lumbar support, mobility, and a compact grey swivel chair are required. It is appropriate for individual workstations and desks with a height of 720 to 760 mm. Procurement teams should plan for two cartons per set, a packaged gross weight of 23 kg, and a reference assembly time of 40 minutes. The reference carton dimensions are 850 x 420 x 720 mm, with a total carton volume of 0.26 cubic meters per set. The indicative loading quantity is 135 sets in a 20GP container at 85 percent space utilization.
