The SD-SET-ADJ-001 Height-Adjustable Student Desk and Chair Set is an unbranded public furniture solution tailored for structured learning and training environments. Visually, the set features a clean, utilitarian layout with an open under-desk storage tray, integrated fixed-position seating connected via a shared steel frame crossbar, and smooth PVC edge trim on all panel edges for a polished, snag-free finish. The curved rigid backrest is contoured to deliver targeted posture support, with a 240 mm tall lumbar support zone, 70 mm thick backrest padding, and 90 mm thick seat cushion positioned to maintain comfortable upright positioning during extended use. The 540 mm clear width between armrests accommodates a broad range of user body types without unnecessary bulk. Constructed for heavy daily use, the set pairs durable composite and steel materials for long-term reliability. The desktop uses 18 mm thick high-pressure laminate over particleboard, while seat and backrest panels are formed from 15 mm thick molded laminate wood-composite, reinforced with 14 mm bent plywood internal supports for both seat and back structures. The frame is built from 1.2 mm thick cold-rolled steel tubing with a powder-coated finish to resist scuffs and corrosion, paired with 0.8 mm thick stamped steel for the under-desk storage tray. Height adjustments use zinc-plated steel bolts and wing nuts, with no additional tools required to shift between 6 height positions, and all feet are fitted with injection-molded plastic end caps to protect floor surfaces. The recline function offers 3 suggested lock positions up to 125 degrees, with tilt tension calibrated to support users up to 120 kg, and the desktop supports a static load of 80 kg. The design carries a 6-year service life, with anti-tip stability tested to 15 degrees, and units can be nested and stacked for compact off-season storage. The set is well suited for K-12 classrooms for daily primary and secondary school lessons, corporate or institutional training rooms for fixed-position session seating, after-school tutoring centers as low-maintenance durable seating, formal exam halls for uniform standardized testing layouts, and temporary school events or meetings where quick reconfiguration is needed. For procurement teams, note each set ships in 2 cartons with a total packaged gross weight of 23 kg, requires 40 minutes of assembly per unit, and 135 sets can fit in a 20GP container at 85% space utilization, supporting large-scale rollouts with predictable logistics planning.
