Product Description

The Mid-Back Upholstered Swivel Executive Chair offers a professional seating solution with a structured, tailored appearance. Its beige padded seat and back are finished with a smooth upholstery surface and visible horizontal seam lines, creating a neat executive look suited to both traditional and contemporary interiors. The contoured back panel includes a defined lumbar support zone, while fixed loop armrests provide continuous elbow and forearm support with matching beige pads and angled metallic-finished side supports. A polished five-star metal base, chrome-plated central gas-lift column, and twin-wheel casters complete the chair’s visual balance of comfort and office functionality. Overall dimensions are 670 x 670 x 1080 mm, with 540 mm of clear width between the armrests. Construction combines padded comfort with a supportive internal structure. The seat uses a 90 mm thick foam cushion over a load-bearing seat pan, with a specified foam density of 45 kg/m3. The back incorporates a padded insert over a rigid internal shell, using 35 kg/m3 foam, and includes a 240 mm high lumbar support zone. The target internal seat pan is moulded plywood or reinforced polymer, while the back frame is tubular steel or reinforced polymer and concealed beneath upholstery. The 50 mm chrome-plated telescoping steel gas lift provides height adjustment and supports 360-degree swivel rotation. Material grade details for the beige upholstery should be confirmed through the supplier bill of materials before purchase. Functional features are designed for daily desk work and meetings. Pneumatic adjustment provides a 520 mm seat height at the stated maximum endpoint. A synchro-style tilt mechanism enables 15-degree back recline with coordinated seat movement, a single-position upright lock secures the working posture, and a side knob adjusts tilt resistance. The chair is intended for users up to 130 kg. Five twin-wheel casters allow omnidirectional movement on hard floors and low-pile carpet, while the fixed loop arms maintain a consistent, formal profile. This model fits private manager offices, open-plan workstations, meeting rooms, reception or consultation areas, and home offices where executive styling is required. Its compact footprint and neutral finish coordinate with wood, tile, vinyl, and low-pile carpeted office environments. Procurement teams should note that one set ships in two cartons, with a packaged gross weight of 23 kg and a reference assembly time of 40 minutes per set. Verification figures include a static seat load of 820 kg, backrest load of 136 kg, base static-load target of 1134 kg, and 100,000-cycle ratings for gas-lift height adjustment and caster rolling durability. Confirm final upholstery specification, assembly hardware, and finish samples when ordering for commercial projects.
