Product Description

Visually, the sets feature a cohesive color palette of pink melamine work surfaces, gray powder-coated steel frames, and blue injection-molded PP plastic trim and floor feet, creating a bright, durable aesthetic suited for learning environments. The single model accommodates one user, while the double model integrates a full-height vertical divider panel between two seat positions to support focused individual work. The cantilever-style sled base has wide, plastic-tipped feet with anti-slip pads, delivering a stable, low-profile footprint that supports unobstructed leg room. Constructed for long-term use, work surfaces and chair panels are made of pink melamine-faced particleboard with PVC edge banding, paired with a gray powder-coated round steel tube frame with 1.2 mm wall thickness for structural rigidity. Under-desk storage panels use 16 mm thick pink melamine-faced fiberboard, while chair seats and backrests rely on 14 mm bent plywood or equivalent reinforced internal frames for support. Height adjustment is enabled by galvanized steel bolt and nut fasteners, with gas-lift components recommended to Class 4 engineering specifications. Blue injection-molded PP plastic floor feet and trim protect surfaces and reduce wear. Functionally, the desk offers 6-position bolt-hole height adjustment with 120 mm total travel, with 20 mm increments to align with student growth. A front-facing enclosed under-desk compartment with open top access holds books and supplies, with a load capacity of 15 kg. The chair features 90 mm thick seat cushions and 70 mm thick backrest padding, with a 240 mm tall lumbar support zone and 540 mm clear width between armrests for comfortable seating. Seat foam has a density of 45 kg/m³ with 65% rebound reference. The chair supports a 125° recline with 3 suggested lock positions, and tilt tension adjustment covers up to 120 kg of user weight. Chairs have a nesting frame design for compact off-season storage. The single desk supports a 60 kg static top load, while the chair seat holds a 120 kg static load. Total set weight reaches 22 kg for the single model and 38 kg for the double model. These sets are suitable for primary school classrooms for younger growing students, secondary school classrooms at upper height settings, tutoring and training centers that require flexible single or double seating layouts, school renovation projects needing standardized classroom furniture, and after-school activity rooms for art and homework use. For procurement planning, each set ships in 2 cartons, with a packaged gross weight of 23 kg per set and a carton volume of 0.26 m³ per set. A 20GP container holds 135 sets at 85% space utilization. Assembly takes 40 minutes per set.
