The Kids Ergonomic Height-Adjustable Study Chair (model KSC-ADJ490-PB) is a purpose-built seating solution designed to support growing users during extended seated tasks, offered in soft pastel pink and pastel blue finishes to complement light, youth-focused interiors. Its streamlined form features a rounded, contoured silhouette anchored by a wide 5-point caster base, with a slim height-adjustment column connecting the base to the seat assembly; two backrest styles are available, including a dual split lumbar design offered in both colorways and a single contoured backrest exclusive to the blue variant, with select pastel pink units fitted with smooth-edged fixed armrests. The chair is constructed for long-term daily use, with an internal support frame made of Q195 carbon steel pipe, paired with glass-fiber reinforced PP connectors for the backrest and a reinforced PP 5-point base accented with subtle colored dot details. Seat and back cushions are padded with high-density polyurethane shaped foam, upholstered in breathable knitted polyester fabric that withstands regular wear from repeated use. The height adjustment mechanism uses a powder-coated steel pole marked with clear graduated height indicators, operated via an ergonomic ABS grip at the pole top, while nylon casters with soft PVC rolling surfaces attach to the base, and all plastic components feature smooth, rounded edge finishes for safety. Functional design prioritizes ergonomic support and practicality: the W-shaped contoured seat pan reduces pressure on the backs of the legs to encourage upright, supported sitting, with a seat height travel range that locks into fixed positions to suit different user needs. The 5-point base enables 360-degree swivel and smooth, quiet movement across hard flooring surfaces without causing scratches, supporting a maximum static load to accommodate stable use over time. This chair is well suited for a range of residential and light commercial spaces, including home children’s study areas paired with compatible height-adjustable desks for homework, reading and writing, early education classrooms and tutorial centers for preschool and primary school learners, and family multi-use activity spaces for art, craft and screen-based learning. It is optimized for users up to 12 years of age and 160 cm in height, and pairs best with an 850 mm height-adjustable study desk to support aligned, comfortable posture. For procurement planning, note that each unit ships across two cartons, with a straightforward assembly process, and bulk loading s are available for full container orders to support large-scale furnishing projects. Buyers can select between backrest styles and color options to match existing space decor, and should confirm variant specifications when ordering to align with preferred armrest inclusion.
