The Adjustable Ergonomic Children's Study Chair with Split Backrest (model KSC-PNK-054, unbranded) features a purpose-built form tailored to growing young users, anchored by its signature dual-lobe split backrest. Each backrest lobe measures 220 mm wide, positioned to independently contour to the natural spine curve, with fixed padded armrests set 180 mm above the seat to support neutral elbow positioning. An integrated wide non-slip footrest runs along the chair’s base, with translucent pink PP caster housings holding soft PU rolling tires that complement the chair’s child-centric aesthetic, while all exposed structural edges are rounded for safety. Its core frame is constructed from 1.5 mm thick powder-coated carbon steel, paired with high-impact food-grade PP structural parts. The seat cushion uses 45 kg/m³ high-density molded PU foam, while backrest cushions feature 35 kg/m³ medium-density PU foam, both upholstered in 280 g/m² breathable three-proof knitted polyester secured with 8 stitches per inch reinforced stitching for long-term wear. The 50 mm diameter Class 3 steel gas lift enables height adjustment, with armrest pads built with soft-touch PU over PP bases, and the footrest platform finished in textured non-slip PP. Overall dimensions are 544 x 770 x 720 mm, with a net weight of 18 kg and 150 kg static weight capacity; the fabric delivers 30,000 Martindale cycles of abrasion resistance, 60% foam rebound resilience, and 10° anti-tilt stability for reliable daily use. Functional features are designed to support healthy seated posture: seat height adjusts 135 mm vertically between 325 mm and 460 mm with multi-position lock, the backrest offers 25° adaptive tilt and 160 mm of height travel to maintain spinal alignment, and casters use gravity-activated auto-lock that engages when user weight exceeds 15 kg to prevent unintended movement during study. The wide non-slip footrest accommodates shorter children who cannot reach the floor, while the split backrest lobes provide targeted lumbar support to encourage upright posture. This chair is suited for home study spaces including children’s bedrooms and dedicated home study areas, pairs with height-adjustable children’s study desks, and is appropriate for after-school tutoring centers and classroom settings. It is designed for users up to 14 years old and 170 cm tall, ideal for children needing structured posture support, and compatible with 2.4 m executive desks for coordinated setups. For procurement, note each unit ships in 2 cartons with a 23 kg packaged gross weight and 0.26 m³ total carton volume, with 85% space utilization in a 20GP container allowing 135 sets per load. On-site assembly requires 40 minutes per set; select orders that align with space layout and age-specific user needs to ensure optimal fit and functional value.
