The UBC-HG-01 is an unbranded high-back gaming and executive office chair with a racing-inspired silhouette. Its blue smooth polyurethane leather or vinyl seat and contoured back create a defined visual profile, while sewn side panels and bolsters give the backrest structure and lateral shaping. Black fabric headrest and lumbar pillows provide contrast and padded support, and black polymer arms and side components complete the commercial look. The chair sits on a painted metal five-star base with black nylon twin casters, presenting a practical layout for desk-facing work, reclined relaxation, and easy turning. Construction combines cushioned surfaces with load-bearing components. The molded polyurethane seat cushion has a 90 mm finished thickness, with the seating zone using an 80 mm molded foam core at 45 kg/m3 density. The backrest includes 70 mm padding over a contoured load-bearing shell, with a 240 mm lumbar support zone. Armrest pads feature a black polymer-capped padded top and hard underside, supported by injection-molded height posts with steel or reinforced polymer brackets. The side recline mechanism uses a black painted steel or reinforced polymer hinge plate and recline lever. Functionality is centered on adjustability for different users and tasks. A pneumatic gas lift provides an 80 mm seat-height working stroke through the right under-seat lever. The side-released backrest reclines continuously through 135 degrees with multi-position lock, while synchronized seat-and-back tilt includes a rear tension knob for user-weight adjustment. Full 360-degree swivel and twin-wheel casters support movement around a workstation. The four-dimensional arm pads offer height adjustment plus a 40 mm fore-aft slide and rotation movement. The strapped head pillow is removable and can be repositioned vertically, and the curved lumbar pillow is removable for placement between the seat and upper back. The clear width between armrests is 540 mm, with a recommended user weight capacity of 150 kg. The chair is suitable for executive workstations, PC gaming rooms, home offices, shared studios, and conference spaces where head and lumbar support are preferred for longer seated sessions. It can be used on hard flooring, wood, tile, vinyl, and low-pile carpet with the supplied casters. Buyers should plan for two-carton delivery, assembly time, replacement-pillow availability, floor protection, and compatibility with desk height and intended users.
