Product Description

The Mid-Back Padded Swivel Conference Chair, model OFC-MB-BUR-520, presents a tailored seating solution with a structured mid-back silhouette, coordinated burgundy upholstery, and a polished aluminum five-star base. Its seat uses horizontal pleated channels, while the padded back features vertical gathered detailing near the upper and side areas, creating a formal appearance suited to organized conference and office settings. Curved fixed armrests are upholstered in the same burgundy material and frame the seat without adjustment controls, supporting a clean, unified visual profile. Construction combines cushioned support with a durable under-seat structure. The seat contains a 90 mm molded polyurethane foam cushion over a load-bearing shell and a 12 mm plywood or equivalent molded composite support board. The back uses polyurethane padding attached to a shaped internal panel, with a defined lumbar support zone. Beneath the seat is a black powder-coated steel multi-position tilt mechanism, paired with a polished telescopic steel gas column and black actuator lever. The polished aluminum alloy base has five radiating legs and black twin-wheel casters, balancing a refined finish with practical mobility. Functionally, the chair supports full 360-degree swivel movement and gas-lift height adjustment with 100 mm of seat-height travel. A synchro-style tilt plate allows a 12-degree maximum back angle, while the under-seat lever provides multi-position locking including an upright setting. A rotary tension knob adjusts recline resistance for occupants up to 130 kg. The fixed arms offer continuous elbow support, and the casters are intended for hard floors and low-pile office carpet, making the chair easy to reposition around meeting tables or workstations. This model is well suited to conference rooms, manager or executive offices, private workstations, consultation and advisory spaces, reception discussion areas, hotel business centers, and business lounges. Its burgundy finish works particularly effectively with wood or dark desking and supports a consistent upholstered seating fleet across formal interiors. For procurement, buyers should note the chair is supplied unbranded as one set across two cartons, with packaged gross weight of 23 kg and a reference assembly time of 40 minutes per set. The upholstery is specified at 50,000 Martindale cycles, seat foam density at 45 kg/m3, back foam density at 35 kg/m3, and recommended occupant load at 130 kg. Projects should confirm flooring compatibility, assembly resources, storage volume, and delivery handling before bulk placement.
