Product Overview & Construction Details

GUOYOU OC-MESH-004 is a grey mesh back mobile meeting chr with white armrests, categorized as a conference and meeting office chr that balances modern aesthetics, functional support and flexible space adaptation. Its visual form features a sleek, streamlined profile: the grey elastic mesh backrest with a horizontal weave pattern is framed by a black reinforced plastic perimeter structure, pred with contrasting white hard plastic armrests that have an angular design, and a polished chrome-plated carbon steel cantilever 4-leg base, delivering a clean, contemporary look that fits diverse professional interior styles. In terms of construction and materials, the backrest uses tensioned grey elastic mesh supported by a black reinforced plastic inner frame with molded rib structure, mntning uniform tension for consistent support. The seat cushion consists of a high-resilience polyurethane foam core with a molded contoured shape, wrapped in a grey woven polyester fabric cover with locked seam construction along the perimeter for durability. The chr’s base is built from bent round tubular carbon steel with welded cross braces and a chrome-plated finish, connected to the seat via a black steel mounting plate. Four black nylon twin-wheel casters are fitted to the leg ends for mobility, and the white one-piece armrests are rigidly mounted to the frame. For practical functions, the tensioned mesh backrest provides passive lumbar and upper back support with continuous r circulation, suitable for extended sitting sessions. The fixed-height cantilever base delivers stable static support, while the rigidly fixed angular armrests offer reliable forearm and upper body support. The dual-wheel nylon casters enable smooth 360-degree swivel rolling across hard office floors and low-pile carpet, and the chr’s lightweight build allows single-person manual movement between spaces without lifting equipment. The cantilever 4-leg frame geometry supports vertical nesting for space-saving storage, accommodating multiple stacked chrs during room reconfiguration. This chr is suited for a wide range of commercial spaces: it serves as standard seating in corporate boardrooms, team meeting rooms and trning venues, where its mobility and stackable design support frequent layout adjustments. It works well as temporary guest or collaborative seating in open plan offices, as space-efficient visitor seating in reception and wting areas, and as durable shared seating in co-working lounges, educational study commons and multi-purpose activity rooms. For procurement planning, the chr ships in a single carton, with partial assembly required to attach casters and armrests. A 2-year warranty is a common reference for commercial-grade mesh conference chrs, though exact warranty terms, material specifications such as foam density and fabric abrasion resistance, and structural performance detls including exact stack capacity and stability test results require direct confirmation from the supplier to align with specific project requirements.
