Product Description

This height-adjustable student desk and chair set, model STD-DC-001, delivers a functional, ergonomic furniture solution tailored for growing users across educational and residential settings. Visual form and layout: The set pairs a cantilever-base desk with a four-leg chair, both finished in a coordinated light gray powder-coat frame with contrasting black non-slip feet. The desk top features a subtle light wood-grain melamine surface with PVC edge banding, and the chair uses a one-piece light gray molded plastic shell with an integrated oval cutout handle at the upper backrest. Clean, streamlined lines ensure the set fits neatly into structured spaces without visual clutter. Construction and materials: The desk and chair frames are built from round steel tubes with a durable light gray powder-coat finish, fitted with height adjustment holes and steel locking pins with black plastic collars for secure positioning. The desk top is a wood-based composite panel, with an open-front gray powder-coated steel storage compartment beneath. The chair’s seat and back shell are molded polypropylene, with internal seat support from a 14 mm bent plywood or equivalent board. Both the seat and backrest are padded, with the 90 mm thick seat cushion using 45 kg/m³ foam and the 70 mm thick backrest using 38 kg/m³ foam, upholstered in 1.4 mm thick material rated for 50000 abrasion cycles. Practical functions: Desk height adjusts across 8 positions via stepless pin-hole mechanism, with a maximum height of 760 mm. The under-desk storage compartment offers 150 mm of internal depth, and a recessed pen groove runs along the desk top’s rear edge. The chair backrest reclines to 125° with 3 lock positions, with tilt tension adjustment covering a maximum user weight of 120 kg. A 240 mm high lumbar support zone promotes proper posture, and the integrated backrest handle simplifies movement. Plastic-tipped bases protect floors and enhance stability, with the desk supporting a static load of 50 kg. Suitable spaces: The set works well in primary and secondary school classrooms, where adjustable height accommodates student growth. It also fits after-school training centers with multi-age users, home study rooms for homework and reading, international school facilities, and exam halls requiring stable, storage-equipped furniture. Procurement considerations: Each set ships in two cartons, with a total gross weight of 17 kg and total volume of 0.11 CBM. Assembly takes 30 minutes per set. The 15 kg net weight makes repositioning manageable, and the durable, low-maintenance materials support long-term use in high-traffic environments.
