Product Description

The Height-Adjustable Student Desk and Chair Set, model STU-DC-001, is an unbranded student furniture solution built for reliable daily use across learning environments. Its visual design balances a clean, functional aesthetic: a white powder-coated steel frame pairs with light wood grain laminated work and seat surfaces, accented by smooth, rounded PVC edge trim for a polished, approachable look suited to learning-focused spaces. The desk and chair share a connected, fixed cantilever steel base that eliminates separate movement between the two pieces, creating a streamlined, stable layout that fits neatly into arranged seating plans. Construction uses durable, purpose-selected materials. The support structure is formed from cold-rolled steel finished with white electrostatic powder coating, secured with zinc-plated steel bolts and lock nuts for height adjustments. Desk top, seat, and back panels use E1 grade particleboard with melamine laminate, sealed with impact-resistant PVC edge banding with rounded corners. The seat incorporates an internal bent plywood support board topped with foam, paired with a curved bent steel tube backrest frame and reinforced internal back frame for structured support. An open-front cold-rolled steel storage bin mounts under the desk, and non-slip black rubber pads fit all six base foot ends to contact flooring surfaces. Functional features support safe, comfortable long-term study use. Both the desk and chair offer stepped height adjustment via bolt fasteners, with five adjustment positions per component to adapt to different user heights. The curved backrest is shaped to support the natural lumbar curve, with structured padding for extended seating comfort. The fixed connected base prevents tipping, while rounded panel edges and covered metal components deliver anti-pinch safety. The integrated under-desk bin provides open storage for stationery, notebooks, and personal school items, and rubber foot pads reduce sliding while protecting hard flooring. The backrest offers a 125-degree recline with three suggested lock positions, and the laminated surfaces deliver reliable scratch resistance for regular daily wear. This set is suited for a wide range of learning spaces. It is sized for individual student use in K-12 standard public and private school classrooms, supporting standard row spacing layouts. Its durable, easy-to-clean construction also works well for high-turnover tutoring and training centers, while its multi-position height adjustment makes it suitable for home children’s study spaces, adapting to growing users across its six-year design service life. The fixed connected structure also makes it appropriate for secure, orderly exam and testing venue setups, and its lightweight, robust build supports temporary learning spaces in community or emergency facilities. Procurement teams should note that each set ships in two cartons, with an 40-minute assembly time per unit. Load planning for 20-foot general purpose containers can accommodate 135 sets at 85% space utilization, supporting bulk orders for institutional fit-outs. Buyers should account for the tool-required height adjustment mechanism when planning setup and long-term facility maintenance, and note that the fixed connected structure is designed for permanent or semi-permanent seating layouts rather than frequent reconfiguration.
