The Yiankang Slate Blue Armless Swivel Adjustable Height Office Chair, model OF-ARM-4STAR-SLB-01, is a streamlined task seating solution defined by its clean, minimalist silhouette and space-efficient proportions. It features a tapered low-back profile upholstered in smooth, matte slate blue 1.0mm PU faux leather, with a polished reflective four-prong metal base fitted with black non-marking rubber glides in place of rolling casters. The armless design creates an unbroken, slim profile that sits flush against desk edges when not in use, with a low overall height that blends unobtrusively into both commercial and residential interiors. Built for regular daily use, the chair uses a multilayer construction anchored by powder-coated steel internal seat frames, a stamped steel control plate, and a steel ball-bearing swivel assembly connected to a Class 3 gas lift cylinder. The seat is padded with high-resilience 45kg/m³ polyurethane foam with molded edge support, finished to a 90mm thickness, while the 10-degree fixed-angle backrest uses 35kg/m³ supportive foam with a rigid internal support board, finished to 70mm padding thickness. The polished four-star base is constructed from chrome-plated steel or aluminum alloy, fitted with injection-molded rubber glides to protect hard floor surfaces. All upholstery uses consistent 8mm stitch pitch for a tailored, durable finish. Core functional features include full 360-degree horizontal rotation, 100mm of pneumatic seat height adjustment controlled by an under-seat nylon paddle lever, and a fixed-tilt mechanism that delivers passive flex under occupant load without manual tension adjustment. The smooth non-porous PU upholstery supports quick wipe-clean maintenance with mild detergent and a soft cloth, resisting water-based stain penetration for easy upkeep. The armless form allows users to sit in flexible cross-legged positions and tuck the chair fully under standard-height desks to free up floor space when not in use, while the stationary glide base prevents unwanted movement in high-traffic areas. This chair is suited for a wide range of settings, including private home office workstations, open-plan office task zones, conference and meeting room guest seating, reception and visitor waiting areas, as well as student study and dormitory desk spaces. It performs particularly well on hard floor surfaces including tile, wood, and polished concrete, where its rubber glides prevent scuffs and scratches without compromising stable placement. For procurement teams, key considerations include noting that select dimensional, foam density, and component material values are engineering references requiring final bill of materials confirmation from suppliers for exact grade and composition details. The chair ships in knock-down packaging, with standard single-unit packing supporting an 20-minute assembly time with included tools. It carries a 12-month standard parts warranty, with a recommended static load capacity of 150kg and suitability for 8 hours of daily use, aligned with light-commercial task seating expectations. Container loading s are available for bulk orders to support large-scale space planning.
