Product Description

Its visual design balances functional practicality with a clean, structured layout: the desk features a flat wood-based work surface paired with an open-front storage drawer positioned directly beneath the desktop, while the matching chair includes a slatted backrest with a top handhold cutout and a contoured seat built for regular daily use. The set’s cohesive frame design creates a uniform look that fits neatly into organized learning spaces. Constructed with durable, low-maintenance materials, the set relies on powder-coated carbon steel square tube frames for both the desk and chair to deliver structural stability. The desk top uses a particleboard core with a melamine laminate surface, edged with injection-molded PP plastic with an anti-collision profile to reduce impact damage. The under-desk storage drawer has a cold-rolled steel shell with punched side panels for light weight and visibility. For the chair, the seat and back shells are one-piece injection-molded PP plastic with horizontal slotted openings for ventilation, paired with padded seating and backrest surfaces. Internal seat support comes from a 14 mm bent plywood or equivalent support board, while height adjustment uses steel spring-loaded locking pins that lock in place at set intervals. All leg bottoms are fitted with wear-resistant PP plastic floor glides, and assembly uses zinc-plated steel bolts and nuts for reliable joins. In practical use, the set offers pin-lock multi-position desk height adjustment, allowing users to modify the work surface height to suit different user heights with consistent 20 mm increments. The fixed open-front under-desk drawer provides accessible storage for books and school supplies, keeping work surfaces clear. The ventilated seat and backrest promote airflow during extended sitting sessions, while the ergonomic backrest contour includes a slight lumbar curve to support natural posture. The backrest handhold cutout makes the chair easy to lift and reposition, and the anti-slip floor glides protect flooring and reduce unwanted movement during use. The chair reclines to 125 degrees with 3 suggested lock positions to accommodate different activity needs. The set is well-suited for a range of commercial and residential spaces. In educational settings, it works in primary school classrooms for 12-year-old students, in middle school classrooms for early teenage users up to 14 years old, and in after-school activity rooms where its sturdy steel frame withstands frequent use by multiple students. It also fits tutoring centers and training rooms, where its lightweight frame supports flexible room rearrangement. For residential use, its compact footprint works well in home study areas, bedrooms, or dedicated study nooks. Procurement teams should note that each set ships in 2 cartons with a total gross weight of 23 kg, with a total carton volume of 0.26 cubic meters per set. Assembly takes 40 minutes per set, and a 20GP container holds 135 sets at 85% space utilization.
