The Height-Adjustable Children's Ergonomic Study Chair (model CESC-555898-ADJ) is a child-sized wheeled seating solution, offered as an unbranded product tailored for supportive long-duration use. Visually, it features a compact, child-proportioned form with a dual-lobe split back support, a padded oval height-adjustable headrest, and a five-point mobile base, offered in pink, blue, and green finishes to coordinate with youth-focused interior palettes. All exposed gaps around the chassis and lift column are fully covered to deliver anti-pinch protection, while upholstery uses consistent 8mm stitch pitch for a neat, durable finished appearance. Construction prioritizes long-term durability and child-safe comfort: seating surfaces use stain-resistant breathable knitted fabric upholstery, with a 60mm thick, 45 kg/m³ high-resilience molded polyurethane foam seat cushion and high-density polyurethane foam backrest fill for consistent pressure distribution. Structural components include a high-strength ABS and PP plastic frame, 2.5mm thick reinforced steel chassis plate, cold-rolled steel gas lift column, reinforced nylon composite five-star base measuring 620mm in diameter, and 50mm PU-wheeled casters. The chair carries a 300kg maximum static load capacity, with a gas lift rated for 100,000 fatigue cycles and fabric rated for 40,000 abrasion cycles, supporting a recommended user weight of 80kg. Core functional features support evolving ergonomic needs: gas-assisted seat height adjustment delivers 200mm of vertical travel, with a minimum seat height of 390mm and maximum seat height of 590mm, paired with 80mm of forward and backward seat depth adjustment for customized fit. The gravity-activated caster locking system automatically secures the chair when a user is seated, preventing unintended movement during focused tasks, while the adjustable backrest reaches a maximum height of 950mm to align with growing spines. Overall dimensions measure 550 x 580 x 980 mm, with a 450 x 470 mm seat cushion suited to child body proportions, and a net weight of 15kg for easy repositioning by supervising adults. This chair fits a range of child-focused spaces: it supports children up to 12 years old during homework, reading, or online learning in home study areas, pairs effectively with 760mm height-adjustable study desks to promote upright seated posture, serves as durable multi-age seating for private tutoring classrooms, delivers postural support for extended reading in dedicated reading nooks, and coordinates with decor in color-matched children’s bedrooms. Procurement teams should note the product ships as one set across two cartons, with a packaged gross weight of 23kg per set, total carton volume of 0.26 m³ per set, and a 40-minute per-set assembly time. A 20GP container holds 135 sets at 85% space utilization for bulk order planning.
