Product Description

The TSK-MESH-MID-RED-SIL mid-back task chair presents a clean office profile with a light gray breathable mesh back, a contrasting red upholstered seat, and a silver-gray molded frame. Integrated fixed loop arms and side back supports give the chair a continuous visual structure, while the polished aluminum five-star base and black twin-wheel casters add a functional, professional appearance. Its layout balances open back support with a padded seat and fixed armrest positioning, creating a distinctive look for desks and shared work areas. Construction combines flexible mesh stretched within a matching molded frame, a red woven upholstered cushion, molded high-resilience polyurethane foam, and a load-bearing seat shell. The seat cushion uses 90 mm thick foam, while the backrest includes 70 mm padding and a 240 mm lumbar support zone. The clear width between armrests is 540 mm. Soft gray polymer pads are fixed to the molded arm supports, and the black steel tilt and height mechanism is located beneath the seat. A polished aluminum base supports five black twin-wheel swivel casters. Designed for everyday desk use, the chair swivels and provides pneumatic seat-height adjustment through a 100 mm stroke, controlled by a visible side lever. Its synchro-style tilt allows a 15-degree back recline with proportional seat movement, and a rear tension control lets the user adjust tilt resistance. The backrest requires a 120 mm travel envelope behind the frame. The casters support mobility across hard floors or low-pile carpet, with no visible wheel locks. The recommended user weight capacity is 136 kg, and the chair net weight is 15.5 kg. This model is suited to open-plan desks, private workstations, conference seating, and residential workspaces where breathable back support and easy movement are priorities. Procurement teams should select hard-floor casters for tile and wood floors, or substitute soft-tread casters for sensitive flooring. Because the armrests are fixed, seating layouts should accommodate their set width. The product is supplied as one set in two cartons, with a packaged gross weight of 23 kg per set and a reference assembly time of 40 minutes. Delivery and receiving planning should allow for the export carton dimensions and multi-carton packaging.
