The GUOYOU OC-MB-001 Mid-Back Mesh Office Task Chair features a sleek, balanced silhouette defined by its two-tone color scheme and compact mid-back profile. Its layout centers on a tensioned grey woven mesh backrest framed in black plastic, paired with a vibrant orange fabric seat cushion that creates a striking visual contrast. Fixed armrests with black horizontal pads sit symmetrically on either side of the seat, anchored by a polished chrome-plated steel 5-star base fitted with black dual-wheel casters. The overall structure presents a clean, functional aesthetic tailored for everyday work environments. Constructed with durable, performance-focused materials, the chair’s backrest uses breathable woven mesh stretched over a black plastic frame with rigid internal support, delivering flexible support and passive lumbar ventilation. The seat cushion combines orange woven polyester upholstery with locked seams over a high-density molded polyurethane foam core with a shaped contour, supported by a plywood inner panel with steel reinforcement brackets. Its armrest assembly pairs black nylon pads with chrome-plated steel supports, while the height adjustment system uses a black-coated gas lift cylinder with a chrome outer tube. A steel tilt mechanism under the seat, controlled by plastic adjustment levers, connects the seat to the 5-star base, which is fitted with soft-tread dual-wheel casters for smooth mobility. Functionally, the chair offers pneumatic seat height adjustment via a right-side lever, with a total vertical stroke of 100 mm. Its synchronous tilt mechanism supports lockable recline up to 12 degrees from the upright position, with a rotary tension knob under the seat to adjust recline resistance. It provides full 360-degree swivel rotation around the central gas lift column, and the five dual-wheel casters enable multidirectional movement across different floor surfaces. Fixed-position armrests with long horizontal pads offer stable forearm support, and the mesh back delivers consistent, breathable support for prolonged seated use. This chair is suited for a range of commercial and residential spaces. In commercial settings, it fits open-plan office workstations, staff administrative desks, meeting rooms, and training areas, where its mobile design supports frequent layout reconfiguration and 8-hour dly use. For residential applications, it works well in home offices with standard-height desks and limited floor space, delivering reliable functionality without excessive footprint. For procurement planning, the chair has a net weight of 14 kg, with a recommended static load capacity of 120 kg to guide user suitability. It ships one unit per carton, with single-person assembly required. Teams should confirm material specifications including fabric abrasion ratings, gas lift certification, and base corrosion resistance directly with the supplier, as these details require official validation to align with specific project requirements.
