Product Description

The Black Mesh Back Padded Seat Folding Office Training Chair with Fixed Armrests, model FTC-MB870is an unbranded static seating solution built for flexible, high-use seating needs. It features a streamlined, professional matte black finish across all components, with a consistent upright profile suited to formal and casual settings alike. When set up, its four splayed steel legs create a stable floor footprint, and fixed PP armrests sit at a consistent height aligned to the seat and backrest. The backrest uses tensioned black woven polyester mesh set into a PA+fiberglass reinforced plastic support frame, with a slight fixed lumbar curve for gentle support. The seat combines a molded plywood base, high-density polyurethane rebound foam padding, and black woven polyester upholstery stitched securely over the cushion. The main frame is constructed from 1.5mm thick powder-coated steel tube with an anti-rust matte coating, connected with zinc-plated steel rivets and lock washers at the central side-pivot X-frame folding mechanism. Non-marring, anti-slip black plastic glides cap each leg to protect hard flooring surfaces. The chair folds completely flat to a slim profile for compact storage, and supports vertical stacking of up to 10 units when folded to minimize storage footprint. It has no swivel, gas lift, recline, or height adjustment functions, retaining a fixed, rigid structure for consistent, stable seating. The breathable mesh back reduces heat buildup during extended sitting, while the padded seat balances support and comfort for users. The design is compatible with retrofittable writing tablets and casters per category standards to support customized use cases. This chair fits a wide range of commercial and select residential spaces: it works seamlessly in corporate training rooms for fast setup and teardown between scheduled sessions, formal conference and meeting spaces for guest and attendee seating, temporary offsite company events due to its easy transport and flat storage, open office collaborative areas for quick reconfiguration during ad-hoc group work, educational institution classrooms and workshops for durable daily high-volume use, and waiting or reception areas for comfortable short-duration guest seating. When procuring this model, note that each unit ships across two cartons, with assembly required per unit; factor in lead times and assembly labor for large orders, and confirm storage space aligns with its stacked and folded dimensions to support efficient turnover between events or sessions. Its durable fabric and steel construction is engineered to withstand frequent use, making it a practical choice for spaces requiring flexible, no-fuss seating solutions.
