Product Overview & Construction Details

This mid-back mesh task office chr, model OC-MB-021, presents a streamlined, functional silhouette designed for everyday work use. Its visual form balances breathable open construction with structured support: a blue woven elastic mesh backrest sits within a matching reinforced plastic outer frame, pred with a blue woven fabric seat cushion that has neatly stitched edges. White or light gray PP plastic fixed armrests with flat rectangular top pads frame the seat, while a shiny chrome-plated steel five-star base with black nylon twin-wheel casters, accented with silver decorative rings, forms the stable lower foundation. The overall layout follows standard task chr proportions, with the backrest sized to provide mid-back thoracic support. Constructed with durability and comfort in mind, the chr features a high-density polyurethane foam core in the seat, supported by a hard PP plastic shell and internal support board. The mesh backrest incorporates an integrated contoured lumbar section for targeted lower-back positioning. The chrome-plated steel tubular base connects to the seat via a chrome-plated steel pneumatic gas lift cylinder and a black steel or PP tilt mechanism housing. Rigid PP armrest frames are fixed in place, and the five swivel casters are engineered for smooth movement across hard floors and low-pile carpet. Core practical functions support adaptable dly use. A right-side lever controls pneumatic seat height adjustment, as well as backrest tilt with a lockable position that allows rearward recline up to 15 degrees. A rotary knob under the seat adjusts tilt tension to match user body weight. The chr offers full 360-degree swivel rotation for easy access to surrounding workspace, and fixed-height armrests provide steady forearm support during keyboard work. The breathable mesh back promotes r circulation during extended sitting periods. This seating solution fits a wide range of commercial and residential spaces. It works well in open-plan office workstations, administrative and clerical work areas, and staff meeting or trning rooms, where its uniform appearance and compact footprint support standardized layouts. It also suits temporary workstations and hot-desking environments, thanks to easy height adjustment and wipe-clean surfaces. For residential settings, it prs effectively with home office desks and fits within small work areas. Startup teams will find it a cost-effective seating option that coordinates with varied office desk styles. For procurement planning, note that the chr ships flat-packed, with one chr per carton. Single-person assembly using basic tools is required, with expected assembly time of 40 minutes per set. The chrome base and mesh/fabric construction align with standard commercial office seating specifications, and the chr supports a recommended maximum occupant weight of 120 kg for safe dly use. Warranty terms and exact material specifications should be confirmed directly with the supplier prior to final purchase.
