Product Description

The Light Grey Upholstered 4-Star Swivel Lounge Armchair (model L-SW-4STAR-LG01) is an unbranded modern minimalist seating piece defined by clean, streamlined forms. Its integrated wrap-around armrests flow seamlessly from the contoured seat shell, paired with a sleek black 4-prong base that creates a balanced, uncluttered silhouette suited to contemporary interior schemes. Overall dimensions measure 760 x 860 x 950 mm, with a 700 mm diameter base footprint that maintains a stable, space-efficient profile without visual bulk. Built for durable long-term use, the chair features 1.2mm thick smooth matte light grey faux leather upholstery, stitched with color-matched high-tenacity polyester thread at 8 stitches per inch to deliver 50000 Martindale cycles of abrasion resistance. The seat holds 120mm thick high-resilience polyurethane foam with 28 kg/m³ density and 55% rebound rate, supported by a 12mm molded plywood core and 14mm bent plywood support board, while the backrest uses 80mm thick matching high-resilience foam shaped to provide built-in mid-back lumbar support. The 2mm thick powder-coated black steel 4-prong base houses a steel 360° rotation bearing rated for 300 kg static load, fitted with hard plastic non-marking glides at each leg end to prevent scuffing on hard flooring. The chair supports a 250 kg recommended static weight capacity, with a fixed 108-degree relaxed reclined back angle that requires no tilt or height adjustment; it offers smooth full rotation around its central axis with no casters, remaining stationary while allowing easy directional access. Assembly requires only included hardware to attach the base to the seat shell, taking 40 minutes per set with no special tools needed. This armchair fits a wide range of public and residential settings, including corporate office lounge and break areas, hotel lobbies, client reception waiting zones, co-working breakout spaces, modern residential living rooms as an accent seat, and contemporary furniture showroom displays. Procurement teams should note units ship as one set across two cartons, with a packaged gross weight of 23 kg per set and total carton volume of 0.26 m³, allowing 135 sets to fit in a 20GP container at 85% space utilization for efficient bulk ordering.
