Constructed with durable, high-quality materials, the set includes a one-piece injection-molded polypropylene desktop and storage shell, vented injection-molded polypropylene chair seat and backrest, and a frame made of powder-coated carbon steel tube with a 1.2 mm wall thickness. The chair seat is supported by a 14 mm bent plywood or equivalent internal support board, while the book basket uses welded steel wire mesh with a gray coating. All frame legs are fitted with wear-resistant non-slip rubber/PP composite foot caps, and height adjustments rely on steel spring-loaded locking pins. The desk edge features a rounded soft-formed PP profile for safety and comfort. Practically, the set offers manual pin-locked desktop height adjustment with 12 positions, and chair height adjustment with 10 positions, to accommodate users of different statures. The lower wire book basket can be set as removable or fixed between desk legs for convenient storage of study materials. Vented seat and backrest surfaces, with perforated or ribbed plastic and air gaps, promote airflow for extended sitting comfort. The chair reclines to 125 degrees, with tilt tension adjustment covering user weights up to 120 kg. Non-slip base feet enhance stability, while the set is tool-disassemblable for compact transport and storage. The desktop supports a static load of 50 kg, and the product has an expected service life of 5 years for classroom use, with seat foam density at 45 kg/m³ and 65% rebound, back foam density at 38 kg/m³, and 1.4 mm thick upholstery rated for 50000 abrasion cycles. Seat cushion thickness is 90 mm, backrest padding thickness is 70 mm, lumbar support zone height is 240 mm, and clear width between armrests is 540 mm. This set is suitable for primary and middle school classrooms as standard daily seating, home study rooms and kids’ bedrooms for homework and remote learning, tutoring centers and training institutions for after-school classes and exam rooms, school libraries and reading rooms for individual reading and research, and international school campuses aligned with global ergonomic student furniture standards. It is also recommended to match with a 2.4 m executive desk where needed. For procurement, note that each set is packed in 2 cartons, with a packaged gross weight of 23 kg, carton dimensions of 850×420×720 mm, and carton volume of 0.26 m³.
