Product Description

The Mid-Back Upholstered Swivel Executive Office Chair, model OFC-MB-PAD-640, presents a professional executive seating form with a dark gray upholstered seat and back. Its padded shell is organized by visible seam-defined panels, giving the backrest a structured, tailored appearance suited to conventional office interiors. Upholstered arm pads sit above dark support housings, while the polished aluminum five-star base and chrome gas lift provide a brighter visual contrast against the dark seating body. Black twin-wheel casters complete the mobile base. Overall dimensions are 640 x 720 x 1030 mm, with a 90 mm finished seat cushion, 70 mm backrest padding, a 240 mm lumbar support zone, and 540 mm clear width between the armrests. Construction combines padded comfort with a conventional office-chair mechanism. The seat uses a molded polyurethane foam pad with a 60 mm seat-foam thickness and 45 kg/m3 density target, while the integrated back cushioning targets 40 mm foam at 35 kg/m3. The arm pads are upholstered and padded, with arm height above the seat visibly set at 180 mm. Beneath the seat, a black synchronized tilt mechanism with a visible steel plate housing links the seating structure to the central chrome gas lift and polished aluminum base. The internal seat carrier is specified as a 12 mm plywood or steel-reinforced target, and the exact upholstery grade, including leather or PU content, should be confirmed through the supplier bill of materials before purchase. Functional features support everyday desk and meeting use. A right-side lever controls pneumatic seat-height adjustment, with 30 mm marked total-height adjustment travel and a 100 mm gas-lift range noted for desk compatibility. The seat and back rotate a full 360 degrees around the central gas-lift swivel bearing. The multi-position tilt mechanism allows 15 degrees of back recline and locks in three positions. The chair carries a recommended user weight capacity of 136 kg and a matching back support rating. Published verification targets include a 710 N downward seat static load for one hour, 100,000 caster rolling cycles, and 100,000 gas-lift height cycles. This unbranded chair is suitable for executive workstations and managers' or professional staff offices, particularly with desks 720 to 760 mm high. It is also appropriate for conference and meeting rooms for meetings lasting one to three hours, where swivel movement and twin-wheel casters help users access seating around boardroom tables. Procurement teams should plan for one set supplied across two cartons, a packaged gross weight of 23 kg per set, and 40 minutes of assembly time per chair. Carton dimensions are 850 x 420 x 720 mm, with carton volume at 0.26 m3 per set and an indicative 20GP loading figure of 135 sets at 85 percent space utilization. Buyers seeking explicit material grades or internal frame composition should request BOM confirmation before finalizing specifications or bulk orders.
