Product Description

The mid-back upholstered swivel executive office chair pairs a clean, contemporary two-tone aesthetic with functional commercial-grade construction, suited for a range of professional and residential work settings. Its visual design features smooth beige PU leather upholstery accented by visible stitched panel seams, framed by a glossy white molded polymer outer shell that wraps the seat sides and outer backrest. The form is anchored by a polished die-cast aluminum five-star base fitted with twin-wheel polyurethane casters with subtle blue-accented wheel housings, creating a sleek, polished profile that balances soft upholstered comfort with crisp, structured lines. Construction prioritizes durable, long-wearing performance: padded seat and back sections sit on an internal molded plywood support frame, with high-resilience foam cushioning tailored for extended sitting. Core movement components include a Class 3 chrome-plated steel gas lift, a powder-coated stamped steel synchro-tilt mechanism with a nylon-lined pivot bushing for smooth, quiet operation, and reinforced nylon caster sockets to prevent loosening with frequent use. The soft PU caster tread is formulated to glide smoothly across low-pile carpet, hardwood, tile, and vinyl flooring without scratching surfaces, reducing the need for separate floor protection mats in most installations. Core functional features support comfortable, flexible working postures. Pneumatic seat height adjustment is controlled via a right-side lever to align with varying desk heights and user leg lengths. The synchro-tilt mechanism moves the backrest and seat at a synchronized ratio for supported recline, with a lockable upright position and an under-seat tension knob to adjust recline resistance to user preference. The chair offers full 360-degree swivel rotation for easy access to adjacent work surfaces, while its fixed contoured seat pan and curved backrest deliver built-in lumbar and thigh support for consistent upright posture without additional adjustable pads. This chair fits seamlessly across multiple spaces: it complements modern executive private offices paired with executive desks, creates a cohesive uniform look in corporate conference and meeting rooms, and maintains open sightlines in open-plan workstations thanks to its mid-back profile. It also works well for home office setups, polished reception and visitor areas, high-traffic co-working spaces, and flexible training rooms where frequent repositioning is common. For procurement teams, key considerations include confirming final material grades with suppliers prior to bulk order, as exact substrate and upholstery grade details are subject to bill of materials confirmation. The chair ships in knock-down form, with standard assembly requiring attachment of casters, gas lift, and seat-back assembly to the base. Bulk container loading quantities are available for full 20ft and 40ft HQ shipments, and the neutral color palette and durable upholstery rating support frequent multi-user use in high-turnover commercial environments.
