The Smart Learning Desk CSC-ADJ520 is a children’s ergonomic study chair engineered to support growing users across daily seated activities. Its design features a contoured padded backrest with a dedicated lumbar support zone, paired with a generously padded seat set between evenly spaced armrests, all mounted on a five-star base fitted with swivel casters for a streamlined, child-friendly silhouette that balances soft, approachable detailing with functional structural lines. The chair is offered in pink, blue, and green finish options to coordinate with varied interior palettes. Construction prioritizes durability and long-term comfort for regular use. The seat core uses high-resilience polyurethane foam, wrapped in a choice of breathable faux leather or fabric upholstery. The backrest uses molded contoured foam with a rigid inner support, finished with a coordinated padded fabric or faux leather cover to match the seat. The support column and adjustment housing are made from injection-molded engineering PP plastic, while the five-star base is available in reinforced nylon or powder-coated steel. Caster wheels are PU-wrapped swivel units with integrated brakes, paired with zinc-plated steel locking pins, axles, and a steel backrest tilt pivot with plastic friction bushing for smooth, reliable operation. Key functional features support adaptable, safe use for young users. The chair offers 8 incremental seat height positions locked via a knob and pin system, paired with backrest height adjustment to grow with the user. A pivoting backrest tilts to follow natural seated posture movement, with 3 suggested lock positions across its recline range, and a rotary dial at the front of the seat pan controls height settings and tilt lock. Casters allow 360-degree swivel and multidirectional movement, with gravity-activated brakes to prevent unintended rolling when occupied. The chair supports a maximum static user load of 80 kg, with tilt tension adjustable to accommodate a range of user weights. This chair suits a range of residential and commercial spaces. In homes, it works well in children’s home study areas paired with a height-adjustable study desk for homework, reading, and drawing, or in multi-use bedroom zones for craft activities and supervised screen time. In commercial settings, it fits private tutoring center classrooms, where its adjustable sizing accommodates students across multiple grade levels. It pairs optimally with a 1200 mm wide height-adjustable children’s study desk for a coordinated ergonomic setup. For procurement, note that each unit ships in 2 cartons, with a reference assembly time of 40 minutes per set. The maximum recommended user age is 14 years, and buyers can select between upholstery and base material options to align with budget and durability needs, as well as choose from available color finishes to match existing decor. The 80 kg maximum static load should be aligned with intended user groups to ensure safe, long-term use.
