Product Description

The Light Grey Fabric Cantilever Conference Office Chair (Model CC-SLD-GRY-01) from Bolongkeli Smart Furniture is purpose-built for professional collaborative and guest seating settings, with a streamlined, functional visual profile that blends polished metallic and soft neutral textile finishes. Its open cantilever sled base creates a sleek, unobstructed silhouette beneath the seat, paired with a distinctive split twin backrest and integrated fixed armrests for a balanced, modern look that aligns with a wide range of commercial interior palettes. The light grey woven polyester upholstery is complemented by matte grey polypropylene structural frames and a reflective chrome-plated base, creating a cohesive, understated aesthetic suitable for both formal and flexible work environments. Constructed for consistent long-term commercial use, the chair combines durable, performance-focused materials across every component. The cantilever sled base is formed from chrome-plated cold-rolled steel tubing, with a 2 mm wall thickness supported by a 1.5 mm thick powder-coated steel backrest bracket and 12 mm molded plywood under-seat support panel. Structural side frames are built from light grey matte polypropylene with internal steel reinforcement, while armrests feature a grey polypropylene frame with integrated padded tops. Seat cushions use high-resilience molded polyurethane foam at 65 kg/m³ density with a 60% rebound rate, paired with high-resilience polyurethane foam backrest pads; the light grey woven polyester upholstery delivers 50000 Martindale cycles of abrasion resistance. All base contact points are fitted with replaceable, non-marking injection-molded polypropylene floor glides that pass 10000 cyclic scratch resistance tests. The chair holds a net weight of 18 kg, with a recommended static load capacity of 125 kg and a sled base static load rating of 150 kg. Key functional features support comfortable, low-maintenance use in high-traffic spaces. The fixed-position frame includes 5 degrees of controlled rearward flex from the cantilever base for gentle, natural movement during seating, with no caster mobility to keep seating positions stable during meetings. The split twin backrest design incorporates separate upper back pads and a dedicated lumbar cushion for targeted ergonomic support, while integrated fixed armrests are positioned at standard typing height to reduce shoulder strain during extended note-taking or device use. The smooth fabric surface allows simple spot cleaning with mild detergent, and replaceable glides reduce long-term floor maintenance needs. Note the chair has a non-stackable fixed frame design, with a fixed position that delivers slight natural cantilever flex for seated comfort. This model is suited for a wide range of commercial work and gathering spaces. It performs reliably as seating arranged around conference room tables for 4-hour collaborative sessions, as guest seating in lobby and visitor reception waiting zones, as short-term seating in open office touchdown spaces for impromptu discussions, as standardized seating in training facilities for staff and program attendees, and as premium seating paired with 2.4 m executive desks in leadership meeting suites. For procurement planning, each chair ships as 1 set across 2 cartons, with a packaged gross weight of 23 kg per set and total carton volume of 0.26 m³ per set; assembly requires 40 minutes per unit.
