Product Description

This children’s height-adjustable study desk and chair set, model CH-STU-95ADJ, is offered as an unbranded public furniture solution purpose-built for young users’ daily learning needs. Visually, it features a streamlined, space-conscious layout that combines a flat work surface, an upper divided integrated bookshelf, and a coordinated mobile task chair, with soft, child-appropriate finishes that blend seamlessly into casual learning environments. The bookshelf’s multi-compartment design sits directly above the work surface, creating a cohesive vertical storage unit without disjointed add-on components, while the matching chair is scaled to align with the desk’s adjustable parameters for a unified look. For construction, the desktop uses an eco-friendly engineered wood core finished with rounded PVC edge trim, supported by a powder-coated steel tube frame. Structural components are formed from durable ABS engineering plastic, while the bookshelf panels are crafted from laminated MDF for smooth, easy-to-clean surfaces. The chair is built on a steel tubular internal frame, fitted with high-density polyurethane foam padding on both the seat and backrest, upholstered in breathable polyester mesh fabric, and mounted on PU soft casters for smooth movement. Functionally, the desk uses a manual hand crank to adjust height across its full travel range, locking securely at any selected position to accommodate growing users. The desktop tilts to a full 60-degree angle, with six positive lock positions tailored to writing, reading, and drawing tasks, and a fixed bookend stop bar along the tilted edge to prevent supplies from sliding off during angled use. A shallow pull-out drawer under the work surface holds stationery and small school supplies, while the upper divided bookshelf stores books, drinkware, decor, and learning materials within easy reach. The chair features a vertically sliding adjustable backrest that aligns to support proper lumbar and spine positioning, a 360-degree swivel five-star base with lockable casters, and padded armrests with adequate clearance for comfortable entry and exit. The set is well suited for a range of residential and commercial learning spaces, including dedicated children’s home study nooks in family bedrooms, multi-use children’s bedroom zones that share floor space with wardrobes and beds, home remote learning setups, after-school tutoring centers serving mixed-age student groups, and Montessori learning environments that prioritize ergonomic support for independent, upright sitting. For procurement teams, key considerations include the set’s two-carton packaging, per-unit assembly time, and load capacity that aligns with standard children’s use cases. The casters are designed to roll smoothly without damaging soft flooring, and the desktop surface resists regular abrasion from daily school supplies. Bulk purchasing for commercial fit-outs can leverage standardized container loading calculations for efficient shipping planning, and the compact footprint allows flexible placement even in smaller learning areas without excess floor space occupation.
