Product Description

The Ergonomic Mid-Back Mesh Office Swivel Chair with Fixed Armrests, model OFC-MESH-MID-001, is a versatile unbranded office task chair designed for consistent seated use across professional and personal spaces. It features a streamlined, low-profile silhouette with a cohesive light gray finish on its reinforced nylon armrests, seat frame, and five-star base, paired with a black mesh backrest and smooth dual-wheel casters that create a understated, functional aesthetic. Fixed integrated loop armrests sit at a set width to support forearms during typing, while the contoured mid-height back aligns with the natural curve of the lower spine for targeted lumbar support. Construction prioritizes durability and breathable comfort: the backrest uses woven elastic mesh stretched over a nylon rib frame to promote air circulation during long shifts, while the seat is upholstered in wear-resistant polyester fabric over high-resilience molded polyurethane foam for even weight distribution. Core structural components include a chrome-plated Class 3 steel gas lift, a powder-coated stamped steel tilt chassis, a bent plywood internal seat support board, and hard-floor PU casters suitable for low-pile carpet as well as smooth hard surfaces. Functional features support flexible, user-centric use: pneumatic seat height adjustment operated via a right-side lever lets users align the seat to their desk surface, full 360-degree swivel enables easy reach to adjacent work areas, and a weight-activated synchro tilt offers a 12-degree backward recline that locks in the upright position. An under-seat rotary knob adjusts tilt tension to match individual user preference, and the chair supports a maximum recommended user weight of 120 kg. This chair fits a broad range of settings, including open office workstations for general staff completing daily desk tasks, compact home offices, short-to-medium duration conference room seating, adult and teen study rooms, and call center workstations where breathable support is key for long seated shifts. It pairs well with executive desks up to 2.4 meters in width. For procurement, teams should note each unit ships in two cartons, requires roughly 40 minutes of assembly per set, and fits efficiently into standard shipping containers for large-scale orders, making it a practical choice for both bulk commercial outfitting and individual residential purchase.
