Product Description

The Mesh Back Cantilever Conference Office Chair (model OFCH-CANT-MESH-625, unbranded) presents a streamlined, professional silhouette tailored to commercial workspace settings, with a cohesive matte black and dark gray color palette that aligns with neutral office interiors. Its fixed cantilever sled base creates a clean, unobtrusive profile, while the open-weave mesh back sits vertically above a generously padded seat, paired with closed-loop fixed armrests that maintain consistent, uncluttered lines around conference tables. Overall dimensions measure 625 x 585 x 1015 mm, with 540 mm of clear width between armrests to accommodate a broad range of users.
Built for long-term commercial use, the chair’s frame is constructed from 16mm diameter powder-coated black steel tubing with a matte epoxy finish, mounted with non-scratch black nylon glides at floor contact points. The backrest uses a black molded PP plastic internal structure shaped into a Y-shaped lumbar contour, upholstered in dark gray breathable woven polyester mesh rated for 50,000 abrasion cycles. The seat features a 14mm bent plywood internal support board, topped with high-density 45 kg/m³ polyurethane foam that forms a 90mm thick cushion, upholstered in black abrasion-resistant woven fabric. Fixed injection-molded black polypropylene armrests attach directly to the frame for lasting structural integrity, with the steel frame tested to 120,000 cycles of static load durability.
Functional design prioritizes comfort for extended seated use: the fixed cantilever frame offers gentle flex for static seating comfort, while the integrated 240mm tall contoured Y-shaped lumbar pad aligns with the natural lower back curve. The 125° backrest angle includes three suggested lock positions, and the open mesh back enables continuous air flow to reduce heat buildup during long meetings. Armrests sit 190mm above the seat surface for relaxed arm support, and the non-swivel, non-rolling design delivers stable placement, with nylon glides preventing scuffs to tile, wood, and vinyl hard flooring. The chair holds a 150 kg static seat load capacity, with a 120 kg recommended user weight limit for single-person use.
This model is suited for conference room seating, where its space-efficient profile supports consistent arrangement around meeting tables, including 2.4m executive desks. It also works for front office guest reception, temporary open office workstations, and training rooms, as its stable sled base allows quick repositioning between sessions, and its stackable-adjacent form supports compact storage when needed. For procurement, note that each unit ships in two cartons with a packaged gross weight of 23 kg per set, requiring 40 minutes of assembly per chair. A 20GP container can hold 135 sets at 85% space utilization, making the model scalable for large-space furnishing projects. There are no brand-specific aftermarket service inclusions for this unbranded SKU.
