The Ergonomic Height-Adjustable Children's Study Chair from Smart Learning Desk, model KSC-SB5862is purpose-built to support long study sessions for growing users, with a streamlined armless, mobile design that balances support and flexibility. Its visual profile is defined by a split dual-wing backrest, smooth contoured seat, and five-star caster base, with understated cohesive finishes that complement both residential and institutional learning spaces. The compact footprint measures 580 x 620 x 820 mm at the lowest seat setting, with a 600 mm diameter five-star base that delivers stable positioning without cluttering floor space. Construction prioritizes durable, child-friendly materials: seat and backrest surfaces use breathable knitted fabric treated with a stain-repellent, easy-clean finish, padded with 45 kg/m³ high-density resilient polyurethane foam that delivers a 60% rebound rate for sustained comfort. The internal support structure relies on a 1.5 mm thick steel tube frame paired with a 14 mm bent plywood internal seat support board, while the central lift column uses powder-coated steel tube, the five-star base and integrated anti-tip foot platform are reinforced polypropylene, casters feature polyurethane tread with polypropylene housing, and adjustment controls use color-matched ABS plastic. The chair weighs 18 kg net, with a 150 kg maximum static load capacity. Core functional features adapt to users across growth stages: gas-assisted stepless seat height adjustment delivers 210 mm of travel, locking at any desired position, while 80 mm of forward and back seat depth travel adjusts to match growing children’s thigh length. The split backrest uses dual independent wing pads that conform to the natural spinal curve to provide lateral posture support, with a 125° recline range and three suggested lock positions for varied task positioning. Gravity-activated sit-brake casters lock automatically under 20 kg or more of seated load to prevent unwanted movement, while 360-degree swivel enables easy access to all areas of a paired desk. The integrated anti-tip footrest ring provides stable foot support for smaller children, and the lift mechanism is tested for 100000 adjustment cycles for long-term use. This chair suits home study spaces paired with height-adjustable children’s desks for daily homework and reading, as well as primary school classrooms and after-school training program environments, accommodating users up to 14 years of age and 165 cm in height, and pairing seamlessly with desks up to 2.4 m in width. For procurement, note that each unit ships in two cartons with a 23 kg packaged gross weight and 0.26 m³ carton volume, requires 40 minutes of assembly per set, and fits 135 sets per 20GP container at 85% space utilization.
