The unbranded ERG-MESH-FR-001 high-back ergonomic office chair features a cohesive black finish, with a tall mesh backrest rising 800mm from the seat surface paired with a generously proportioned 510mm wide, 500mm deep seat pan. Its compact, streamlined form sits atop a 350mm diameter steel five-star base, supporting smooth movement without excessive visual bulk, designed to balance professional aesthetic with casual rest functionality. The chair is built for long-term durability, starting with a breathable geometric-patterned polyester mesh backrest upholstery that flexes with user movement. The seat pairs matching geometric mesh over 60mm thick, 45kg/m³ high-density resilient foam for cushioned, pressure-relieving support, while the headrest uses a padded mesh-covered cushion with an internal foam core. The internal support structure combines reinforced nylon and steel for the seat and back frame, anchored to a powder-coated heavy-duty steel five-prong base. Soft molded PU arm pads sit on PA/nylon support brackets, and dual-wheel silent PU/nylon swivel casters with metal axles attach to the base. The seat mechanism uses a thick-gauge steel multi-lock tilt chassis, paired with an SGS-certified Class 4 steel gas lift rated for 120,000 durability cycles, supporting a maximum recommended user weight of 204kg. The frame carries a 120kg static load capacity, and the five-star base holds an 1136kg static load rating. Total assembled dimensions measure 690 x 686 x 1350mm, with a maximum adjustable seat height of 520mm, and the unit weighs a maximum of 19.5kg when fully assembled. The chair delivers comprehensive ergonomic support for extended use. Pneumatic seat height adjustment operates via a side lever with a 100mm stroke, while the backrest offers lockable recline from 90 degrees upright to 135 degrees reclined, with adjustable tilt tension to match user preference. 3D armrests adjust for height, width, and pivot angle to cradle forearms, and the multi-axis headrest offers 60mm of height travel, 35 degrees of angle adjustment, and 40mm of depth adjustment to support the neck and cervical spine. A retractable pull-out footrest slides out from under the seat to support lower legs during reclined rest, while the contoured mesh back zone provides adaptive lumbar support that flexes to match the natural lower back curve. The dual-wheel casters roll smoothly across hard floors and low-pile carpet for unobstructed movement. This chair suits a broad range of public and private seated spaces. It supports 8+ hours of daily desk work in private office workspaces, fits compact home office setups with its recline and footrest for short rest breaks, and stands up to multi-user wear in open-plan task workstations and coworking spaces, where its wide range of adjustable features accommodates diverse body sizes and sitting preferences. It also works well for study and gaming spaces, supporting both focused task work and casual leisure use, and serves as appropriate secondary seating in conference rooms for extended seated discussions.
