The Armless Light Gray Upholstered Swivel Lounge Chair (model SL-F4S-LG-01, unbranded) presents a clean, contemporary silhouette defined by its streamlined armless profile and understated light gray woven polyester upholstery. Its form balances soft, rounded seat and back contours with a sleek polished metal four-star base, creating a visually light presence that avoids visual clutter in open layouts. The design’s unobstructed sides eliminate protruding armrests, supporting seamless positioning in tight or grouped arrangements without blocking sightlines or movement paths. Built for regular public and private use, the chair features a 12 mm thick molded plywood inner shell wrapped in molded high-resiliency polyurethane foam: 100 mm thick seat foam with 45 kg/m³ density and 45% rebound rate, paired with 80 mm thick back foam, secured with double parallel side seam stitching at 8 stitches per 30 mm for durable seam integrity. The 360-degree swivel function operates via a precision steel ball bearing unit mounted to a 1.5 mm thick polished chrome-plated steel central stem, connected to a 3 mm thick polished die-cast aluminum four-star base with 700 mm span. Each base prong is fitted with non-marking black TPE rubber floor protection pads, and the upholstery underside is lined with black non-woven polypropylene fabric. Overall dimensions measure 890 x 970 x 1000 mm, with 460 mm seat height, 560 mm seat depth, 680 mm seat width, and 540 mm backrest height, set to a fixed 12-degree relaxed lounge recline with no adjustable tilt or height functions. The chair supports 136 kg static load, weighs 20 kg net, and its smooth fabric surface allows regular vacuuming and spot cleaning for easy maintenance. This chair suits a broad range of spaces, including office reception areas, open lounge collaboration zones, executive office breakout corners, high-traffic hotel lobbies, contemporary residential living rooms, and coworking space common areas. It is designed for paired use with a matching upholstered ottoman to complete lounge settings. For procurement, note each unit ships across two cartons with a 25 kg total gross weight, requires 40 minutes of assembly per set, and its light neutral tone coordinates with most modern interior palettes. The wide four-star base delivers reliable stability during regular swivel and seating use, while the armless form offers flexible access to suit compact layout configurations.
