Product Description

The set features a cohesive slatted, ergonomic design with a gray powder-coated steel frame, matte injection-molded PP plastic work surface and seating components, and a matching under-desk wire mesh book basket, creating a streamlined, functional profile suited to both institutional and residential settings. The desk includes a recessed pen groove along its rear edge for small supply storage, while the chair’s curved seat edge and concave sitting surface align with natural seated posture to reduce strain during extended study sessions. Constructed for long-term daily use, the set pairs a powder-coated carbon steel tube frame and stamped steel connecting brackets with durable PP plastic surfaces. The desk rests on telescopic legs with steel spring-loaded locking pins, offering 8 distinct height positions to adapt to growing users. The chair’s seat and backrest feature vertical slotted ventilation gaps for consistent breathability, with internal support from 14 mm bent plywood or equivalent reinforced structures. The 90 mm thick seat cushion uses 45 kg/m³ foam with 65% rebound, while the 70 mm thick backrest uses 38 kg/m³ foam, both covered in 1.4 mm thick abrasion-resistant upholstery rated for 50000 cycles. A perforated PP plastic inner shelf adds desk storage, the detachable welded steel wire basket mounts between desk legs for book storage, and black non-slip plastic glides on all base ends protect floors and prevent shifting. The desk supports a static load of 80 kg, and the chair’s five-star base meets a 150 kg reference load standard, with a total net set weight of 18 kg. The backrest reclines to 125° with 3 suggested lock positions for customizable support. Ideal for primary and middle school classrooms, home study rooms, tutoring centers, training institutions, and international school facilities, the set fits standard single-student workstation layouts and aligns with common global educational furniture dimension guidelines. Procurement teams should note that each set ships in 2 cartons with a gross weight of 23 kg and total volume of 0.26 m³, with a 20GP container holding 135 sets at 85% space utilization. Assembly takes 40 minutes per set, and the clear 540 mm width between armrests accommodates users across the recommended age range.
