The SCH-DC01-LG-ADJ Height-Adjustable Connected Single-Student Classroom Desk and Chair Set from Yili Furniture delivers purpose-built, durable seating and work support for a wide range of learning environments. The set features a unified cantilever sled frame with an integrated, connected desk and seat structure, finished in a coordinated light grey and off-white palette that blends seamlessly into structured learning spaces. Its anti-tip T-sled base creates a stable footprint, with non-marring black injection-molded PP glides at floor contact points to protect flooring and cut down on sliding noise. All exposed edges carry a rounded safety profile to reduce incidental contact injury risk during daily use. Construction prioritizes long-term durability across high-traffic settings. The desk work surface uses a 1.2mm thick textured light grey molded PP/ABS composite with HPL wear resistance, supported by a 1.4mm wall thickness cold-rolled oval steel frame finished in off-white electrostatic powder coat over anti-rust primer, with full continuous welds at all tube joints. The seat and backrest are formed from impact-resistant light grey molded PP/ABS with internal reinforcing ribs, paired with a 14mm bent plywood internal seat support, while the ergonomic backrest features a 10-degree backward rake to deliver lumbar support through extended seated sessions. Telescoping steel adjustment sleeves with black lock rings connect to zinc-plated steel locking bolts for secure height changes, with five fixed adjustment positions set at 30mm vertical increments for both desk and seat heights. A front-access pull-out undermount PP drawer sits beneath the desk surface to hold notebooks, writing tools and small personal study supplies. This set supports a maximum user height of 1800mm, making it suitable for K-12 general classroom fixed-row seating, training center and vocational tutorial spaces, public and school library individual study carrels, standardized exam halls, temporary event or pop-up classroom layouts, and dedicated home study areas for school-age children. The desktop holds a 50kg static load, and the height adjustment mechanism is engineered to withstand 100000 adjustment cycles for extended service life. For procurement planning, each set ships across two cartons, with a 40-minute per-set assembly time, and fits 135 sets in a 20GP container at 85% space utilization. The fixed connected frame is not stackable, but its lightweight 22kg net weight allows easy repositioning for flexible space arrangements. The coordinated neutral finish supports consistent visual alignment across large seating installations, while the bolt-locked adjustment system enables simple, tool-accessible height modifications to match varied user needs across multi-age learning environments.
