Product Description

This height-adjustable student desk and chair set, model SDC-ADJ-01, delivers functional, ergonomic seating and workspace solutions for varied educational and residential settings. The set features a cantilever C-leg desk frame paired with a four-leg chair frame, creating a streamlined, space-efficient silhouette that fits neatly into standard row-based layouts without excess bulk. The perforated seat and backrest add a subtle textured visual element, while the powder-coated steel framing lends a clean, durable finish that aligns with casual to formal learning environments. Constructed for long-term daily use, the desk has an MDF core worktop with a melamine laminate surface and plastic edge banding, supported by a powder-coated round steel tube frame in a cantilever C-leg design. An under-desk storage tray, made from single-piece grey injection-molded ABS plastic, provides easily accessible storage for supplies. The chair features perforated injection-molded polypropylene (PP) plastic seat and back panels, with internal support from a 14 mm bent plywood seat support board and 14 mm bent plywood/composite reinforced back frame, mounted to a powder-coated four-leg steel tube frame. Height adjustment uses a steel telescopic tube with spring-loaded pin lock, and all eight contact points are fitted with black hard PVC anti-slip floor protectors. The seat cushion is 90 mm thick with 45 kg/m³ foam and 65% rebound, while the 70 mm thick backrest uses 38 kg/m³ foam, covered by 1.4 mm thick upholstery with 50000 cycle abrasion resistance. Practical functionality centers on 8 desk height positions with 120 mm total travel, accommodating flexible use across different user statures. The grid-perforated seat and backrest enable continuous air flow for ventilated seating during extended sessions. Ergonomic support comes from a curved backrest with a lumbar contour shaped to match natural spinal alignment, with a 125° recline angle and 3 suggested lock positions, plus tilt tension adjustment for users up to 120 kg. The chair also offers 360° swivel with 5-caster multidirectional movement for easy repositioning, while the desk static load capacity reaches 80 kg. The full set weighs 15 kg, with a lumbar support zone height of 240 mm and 540 mm clear width between armrests. This set is suited for primary and secondary classrooms, where it fits standard row configurations and aligns with height grading standards, as well as school tutoring rooms for small-group study and after-school instruction. It works well in home study spaces as dedicated children’s work areas, and fits naturally into training center classrooms for vocational and adult training, plus exam halls for standardized examination room arrangements. It pairs with a 2.4 m executive desk for mixed-use workspace setups. For procurement planning, each set ships in 2 cartons with a gross packaged weight of 23 kg and total carton volume of 0.26 m³, with carton dimensions of 850×420×720 mm. Assembly takes 40 minutes per set, and a 20GP container holds 135 sets at 85% space utilization, supporting bulk ordering for institutional projects.
