The Mid-back Ergonomic Mesh Office Task Chair with Fixed Loop Armrests, model MTSH-MB-590GY, is a versatile unbranded seating solution designed for consistent daily use across commercial and residential settings. Its streamlined visual profile pairs a contoured mesh back with a neatly upholstered seat, supported by a sleek five-star base that balances a compact footprint with stable structural presence. Fixed loop armrests connect directly to the back frame, creating a cohesive, uncluttered silhouette that fits seamlessly into a range of interior schemes without excess decorative detailing. Constructed for enduring performance, the chair features a tensioned polyester mesh backrest set over a PP lumbar support frame, paired with a 50mm thick high-resilience cold-cure molded foam seat wrapped in wear-resistant polyester fabric. Its structural core includes a 2mm thick steel tilt mechanism housed beneath a PP outer back shell, supported by a glass-fiber reinforced nylon five-prong base fitted with 60mm diameter dual-wheel PU soft tread casters. A Class 3 black painted steel pneumatic cylinder facilitates height adjustment, while a 12mm thick MDF board forms the internal seat support structure. Functional design elements prioritize user comfort across extended use. The chair offers lever-operated seat height adjustment with 100mm of vertical travel, 360-degree smooth swivel rotation, and a 12-degree backward synchro tilt with user weight tension adjustment, plus three lock positions for a 125-degree recline. An integrated fixed ergonomic lumbar support zone aligns with the natural curve of the lower back, and the soft dual-wheel casters roll smoothly across both hard flooring and carpeted surfaces. The breathable mesh backrest supports airflow to reduce heat buildup during prolonged sitting. This chair is well-suited for open plan office workstations supporting eight hours of daily individual desk work, compact home office spaces paired with standard desk sizes, and short to medium duration use in small meeting rooms. It also holds up to rotating multi-user use in shared hot-desking environments, suits the mobility needs of administrative staff workstations, and fits quiet, extended study use in college library spaces. Procurement teams should note that each unit ships across two cartons, with an assembly time of 40 minutes per set. The chair supports a recommended static user load capacity aligned with its component ratings, and its durable material construction is engineered to withstand frequent, repeated use in high-traffic shared spaces. Order volume planning can reference standard 20GP container loading figures for efficient bulk shipping coordination.
