Product Description

The UBC-MESH-MB-GRY-01 is an unbranded mid-back ergonomic task chair designed for daily desk use where breathable support, straightforward adjustment, and rolling mobility are priorities. Its overall form is structured around a light grey polymer outer back frame with a woven light-grey elastic mesh panel. The dark grey upholstered seat creates a measured visual contrast, while the grey T-shaped fixed armrests, grey nylon five-star base, and black twin-wheel casters complete a neutral commercial appearance suited to coordinated grey office interiors. The chair’s layout places the user within a 650 mm wide and deep footprint with a 1040 mm overall height. The backrest includes 70 mm of padding thickness and a 240 mm high lumbar support zone, while the finished seat cushion is 90 mm thick. The clear width between the armrests is 540 mm. Fixed armrests provide consistent support without adding width-adjustment complexity, and their rounded padded contact pads offer a comfortable resting surface during keyboard or writing tasks. Construction combines a molded foam seat cushion upholstered in dark grey fabric with an elastic mesh back and polymer support structure. The lumbar mechanism uses a grey polymer shell with curved support wings and a circular tension knob. Under the seat are a black metal-reinforced tilt mechanism and a steel gas lift with a black or dark-grey center column. The grey nylon five-star base supports black twin-wheel nylon casters, balancing light handling with a stable rolling foundation. Functional features include a 360-degree swivel seat and 100 mm of pneumatic height travel controlled by an under-seat lever. The synchronized tilt mechanism allows a 15-degree backward recline, with tension adjusted through the rear lumbar knob. The curved lumbar support applies pressure to the lower mesh zone through the central rotary control, helping the backrest conform to individual posture preferences. The five casters distribute load around the base and are intended for hard floors or low-pile carpet. This chair is appropriate for open-plan office workstations, administrative desks, home offices, study rooms, hot desks, and temporary meeting positions. It is especially relevant where a compact mid-back profile is preferred. Procurement teams should note the 120 kg recommended user weight, fixed armrest configuration, 40-minute reference assembly time, and delivery as one set in two cartons. The neutral finish and practical movement features make it a sound choice for multi-user and flexible seating environments.
