Product Description

The Black Mesh Ergonomic Task Chair with Adjustable Arms and Five-Star Base is a practical seating solution for professional and home work environments. Model ETC-MESH-BK-501 is supplied without brand labeling and presents a clean, neutral appearance suited to interiors where a coordinated black finish is preferred. Its upright, contoured form combines a breathable mesh back with a padded fabric seat, while the five-star base and twin-wheel casters create a familiar mobile task-chair silhouette. Overall dimensions are 650 by 650 by 1110 millimeters, with 540 millimeters of clear width between the armrests. The backrest uses black flexible mesh stretched within an injection-molded polymer outer frame, which includes integrated lower side support. The contoured seat is built with molded foam covered in black woven fabric, featuring a 90 millimeter cushion, 45 kilogram per cubic meter foam density, and a 240 millimeter lumbar support zone. A 70 millimeter padded backrest section adds visible softness while retaining the mesh-backed structure. Black polymer arm pads and support posts complement the molded back frame, and the chair rests on a black nylon five-star base. A chrome steel gas-lift tube with a black telescopic cover connects the seat to the base, while a black metal tilt mechanism with multi-lever controls is positioned beneath the seat. Functionality is centered on adjustable ergonomic support. The pneumatic cylinder provides 90 millimeters of seat-height travel, allowing the seat to be set between 450 and 540 millimeters high. The synchronized recline allows the backrest to move to 118 degrees together with a matching seat tilt, helping maintain coordinated support as the user changes posture. Users can lock the backrest in upright, mid-recline, or full-recline positions. The pillar-mounted armrests offer 80 millimeters of height adjustment and pads that rotate 360 degrees. Swivel movement and twin-wheel casters support easy turning and movement around a workstation. The chair is suitable for individual workstations, administrative desks, and home offices requiring mesh-back support through an eight-hour workday. It is also appropriate for hot desks, meeting rooms, and temporary staff seating where mobility and understated black upholstery are useful. Procurement teams should note the stated 136 kilogram recommended user weight capacity, 15.5 kilogram net weight, and component durability ratings including 100,000 caster rolling cycles, 100,000 gas-lift height-adjustment cycles, and 50,000 Martindale cycles for back mesh abrasion resistance. Each set ships in two cartons with a packaged gross weight of 23 kilograms and a reference assembly time of 40 minutes, making planning for receiving, storage, and installation important when ordering multiple units.
