Product Description

The Cognac Upholstered Mid-Back Executive Swivel Chair with Polished Aluminum Base presents a refined executive-office silhouette through its warm cognac upholstery, tailored edge seams, continuous smooth back facing, and bright polished metal structure. Its mid-back form is paired with matching upholstered arm pads, curved polished die-cast aluminum supports, and a five-star aluminum base, giving the chair a structured yet inviting appearance suitable for professional interiors. The black steel tilt mechanism, black twin-wheel casters, and chrome-plated telescopic gas lift provide visual contrast beneath the upholstered seat and back. The seat uses an 80 mm molded foam pad over a structural deck, while the finished cushion thickness is 90 mm. The backrest combines 70 mm padding with a concealed internal frame reinforced by 2.0 mm steel. The seat deck is built with 12 mm molded plywood or steel-reinforced composite construction. Seat foam density is 45 kg/m3 and back foam density is 35 kg/m3, with the 1.2 mm smooth cognac upholstery finished with precise seams. A 240 mm lumbar support zone and 540 mm clear width between the armrests support a balanced seating layout. Functionality centers on 360-degree swivel movement and pneumatic seat-height adjustment operated by a right-side lever through an 80 mm lift stroke. The synchronized seat-and-back tilt offers a published maximum back angle of 15 degrees, with three lockable positions selected through the visible side lever. A front rotary tension knob adjusts backward resistance for users up to 150 kg. Fixed armrests provide upholstered elbow support, while five 60 mm twin-wheel casters support mobility on hard floors. The chair is recommended for wood, tile, vinyl, or sealed concrete surfaces. This model fits manager and executive desks, private workstations, meeting rooms, reception areas, and consulting rooms where a polished, tailored chair is desired. It is intended for one adult user in normal single-shift, 8-hour office seating duty. Procurement teams should note the unbranded model EXEC-MB-CN-AL5 is supplied as one set across two cartons, with packaged gross weight of 23 kg and reference assembly time of 40 minutes per set. The abrasion acceptance value is 50,000 Martindale cycles, which can be reviewed against expected usage and upholstery maintenance needs.
