The Height-Adjustable Ergonomic Children's Study Chair, model CH-ERG-KID-001 from Smart Learning Desk, features a purpose-driven visual layout centered on a dual-split backrest and streamlined five-star base that balances a playful, approachable silhouette with structured ergonomic framing. The chair is offered in 3 color options to coordinate with varied interior palettes, with fixed curved armrests and an integrated foot platform that create a cohesive, uncluttered profile suited to youth-focused spaces. Its construction prioritizes durable, child-safe material selection: the seat uses a 90 mm thick cushion built around a 35 mm high-density molded polyurethane foam core, supported by a 14 mm bent plywood internal board, with upholstery rated to 30000 Martindale abrasion cycles. The 70 mm thick padded split backrest pairs breathable mesh fabric over a PP plastic frame to deliver targeted support across the 240 mm tall lumbar zone, with 540 mm of clear width between armrests. The 2 mm thick powder-coated steel lift column houses a gas spring rated for 10000 adjustment cycles, connected to a reinforced nylon five-star base fitted with floor-protecting soft tread casters tested to 20000 rolling cycles. Armrests are constructed from injection-molded PP with soft TPE padded tops, and height adjustments are secured with zinc-plated steel locking clamps and hand levers. The entire unit has a net weight of 13 kg and supports a maximum static user weight of 80 kg. Practical functions are tailored for growing users: 8 seat height positions are adjusted via a hand-crank mechanical lift that sets seat height from 390 mm to 600 mm above the floor, paired with a sliding seat pan offering 80 mm of forward and backward travel to accommodate varying thigh lengths. The independent split back panels move to follow spinal curvature for dynamic lumbar support, while the backrest locks into 3 recline positions up to 125 degrees. The wide five-star base delivers 10 degrees of static tilt resistance without tipping, and 360-degree swivel casters move smoothly across hard flooring and low-pile carpet. Fixed curved armrests position forearms at a neutral angle for writing and typing, and the integrated height-matching PP footrest provides stable support for younger users. The chair is suited for children’s home study spaces, where it pairs with height-adjustable study desks for users up to 14 years of age, as well as training and tutorial centers, as its surfaces are easy to clean and sanitize and its dimensions align with standard classroom study desks. Its compact footprint also fits neatly into bedroom study nooks adjacent to single beds, and it is compatible with height-adjustable children’s desks with a 760 mm desktop height. For procurement, note that each unit ships in 2 cartons, with a packaged gross weight of 23 kg per set, a carton volume of 0.26 m³, and a reference assembly time of 40 minutes per set. A 20GP container holds 135 sets at 85% space utilization. The chair is rated for 8 hours of daily use, confirmed by ergonomic testing.
