The Height-Adjustable Ergonomic Kids Study Desk and Chair Set with Attached Bookshelf (model KDS-9580-TILT-SET) is an unbranded child-sized study solution designed to support growing users through their primary school years. Visually, the set presents a streamlined, child-centric layout: the desk integrates a raised upper bookshelf with open divided compartments at its rear, while the matching chair sits neatly beneath the work surface to minimize unused floor space. Its soft rounded edge detailing and neutral, easy-coordinate finish suit a range of interior palettes. The desk frame is constructed from powder-coated carbon steel, paired with an 18mm thick E1-grade MDF desktop finished with a matte easy-clean laminate and soft rounded PVC edge banding. The attached bookshelf uses matching 15mm thick E1-grade MDF for visual consistency. The chair features a thinner powder-coated carbon steel internal frame supported by a bent plywood seat base, padded with high-density high-resilience polyurethane foam and upholstered in breathable woven polyester fabric. It rides on 50mm diameter PU soft tread casters designed to glide smoothly without damaging hard flooring. Functional design is tailored to long-term child use: the desk uses a hand-crank mechanical lift that locks in small increments to adjust height, with a stepless friction lock that tilts the desktop to a maximum 45 degrees to support writing, reading, and drawing positions. The chair offers tool-free sliding height adjustment for both the seat and backrest to align lumbar support with a child’s developing spine, and its gravity auto-lock casters lock automatically when a child is seated to prevent unwanted movement. The wide splayed desk leg base with floor contact pads provides anti-tip stability, while the integrated bookshelf keeps frequently used books, stationery, and reading materials within easy reach. This set fits well in compact children’s bedroom study areas for daily homework, reading, and art activities, as well as in after-school tutoring classrooms where proper seated posture is important for extended study sessions. It accommodates users up to 12 years of age. For procurement, note that each set ships in two cartons, with an assembly time of 40 minutes per unit. The set supports daily use of 8 hours per day, and pairs well with complementary accessories including clip-on LED desk lamps, detachable book stands, and pull-out under-desk storage drawers. Load planning for 20-foot containers accounts for 135 sets at 85% space utilization for bulk orders.
