Product Description

The JUESHANGDA model LGE-SWL-PUR-4PRONG-01 armless contoured purple fabric swivel lounge chair delivers a sculptural, contemporary seating solution that balances aesthetic appeal with durable, functional design for both public and private settings. Visually, the chair features a streamlined, armless silhouette defined by smooth, contoured lines, upholstered in rich deep purple woven polyester tech fabric, paired with a polished chrome four-prong base that lends a sleek, refined metallic accent to the form. The compact, balanced layout sits neatly within varied floor plans without overwhelming surrounding interior elements. Construction is built for consistent long-term use across high-traffic environments. The seat and back wrap a rigid internal support structure of 12mm bent plywood, topped with molded polyurethane foam: seat foam carries a density of 45 kg/m³, while back foam measures 40 kg/m³ with a 45% rebound rate, all covered by 1.2mm thick woven polyester upholstery over a fire-retardant spun polyester interliner rated for 50000 double rubs of abrasion resistance. The central support is a 2mm wall thickness polished chrome-plated steel tube connected via a steel ball bearing swivel joint to the seat structure, anchored to an 8mm wall thickness polished die-cast aluminum four-prong base fitted with non-marking rubber glides at each tip. Key functional features support comfortable, low-fuss use: the integrated concave lumbar curve and winged curved upper back deliver targeted support for the lower back, shoulders and upper torso, set to a fixed 105-degree relaxed lounge recline with no tilt or height adjustment for consistent posture support. The 360-degree smooth swivel mechanism allows easy reorientation, while the armless design removes protruding barriers to enable flexible seating positions and unobstructed access. Non-marking glides protect hard floor surfaces from scuffs and damage during movement. The chair is well suited for a wide range of spaces, including corporate office reception lobbies and waiting zones, open-plan office breakout areas, co-working common spaces, executive office guest seating areas, hotel lounge zones, and residential modern living rooms or reading nooks, where its bold finish and sculptural form serve as a complementary accent piece while meeting the durability demands of frequent public use. For procurement planning, note each unit ships in two cartons with a total packaged gross weight of 23 kg, requiring 40 minutes of assembly per set. The chair supports a static weight capacity of 136 kg, with an 18 kg net weight, and fits 135 sets per 20GP container at 85% space utilization for efficient bulk shipping planning.
