Product Description

Its visual design features a clean, functional layout: the desk pairs a laminate work surface with a slender powder-coated steel frame, while the chair incorporates a perforated polypropylene seat and backrest mounted to a cantilever-style bent steel frame, creating a cohesive, space-efficient profile suited to structured group settings. Construction prioritizes durability and ergonomic support. The desk frame uses 1.2mm wall powder-coated round steel tubing, topped with a laminated particleboard surface finished with a 2mm PVC edge for impact resistance. An under-desk storage tray is moulded as a single piece of ABS plastic for seamless, easy-to-clean storage. The chair frame shares the 1.2mm powder-coated bent steel construction, with perforated injection-moulded PP seat and back panels that enable consistent airflow. A 19mm diameter round steel footrest bar runs across the chair’s lower front frame, while a 14mm bent plywood (or equivalent) internal support board reinforces the seat structure. Height adjustment relies on a steel bolt and nylon knob assembly, and each unit sits on four black, non-marking injection-moulded PP floor glides to prevent surface scuffing. Practical functions are tailored to frequent, varied use. The desk offers 5-position manual height adjustment via side bolts, adapting to different user statures, and its fixed open-front plastic tray provides accessible storage for supplies. The chair supports mild back-recline through cantilever frame flex, reducing prolonged sitting fatigue, and its dense perforation pattern delivers continuous ventilation. The set supports static loads of 80kg on the desk top, 120kg on the chair seat, 60kg on the chair backrest, and 15kg in the desk drawer, with floor glides tested to 20000 abrasion cycles. Chairs stack vertically up to 10 units for compact storage during room reconfiguration. Suitable spaces span primary and secondary classrooms for daily study and exams, training centres and tutoring rooms for short courses and workshops, after-school activity rooms for clubs, art sessions, and homework groups, international school facilities aligned with global furniture standards, and examination halls as compact individual workstations. Procurement considerations include packaging of one set across two cartons, with a 40-minute assembly time per set, a packaged gross weight of 23kg, and a carton volume of 0.26 cubic metres. A 20GP container holds 135 sets at 85% space utilization, supporting bulk order planning for educational institutions. The recommended matching desk size aligns with 2.4 metre executive desks for administrative or combined workspace configurations.
