Product Description

The Black Upholstered Wrap-Around Bucket Lounge Armchair, model LB-BKT-900-BLK, is an unbranded lounge seating piece defined by its sleek monolithic silhouette. It features a seamless wrap-around arm-back structure that flows into a wide tapered plinth-style base, with no exposed legs to break its clean, sculptural line. The smooth matte black upholstery creates a uniform, refined look that balances softness and structural definition, with consistent stitching that reinforces its smooth, uninterrupted form. Its construction is built for lasting residential and light commercial use, starting with a 25mm thick kiln-dried hardwood plywood internal frame paired with a 14mm bent plywood seat support board. The hidden swivel base uses a powder-coated steel rotating plate, fitted with non-marking felt glides to protect floor surfaces. The seat core uses high-resilience polyurethane foam with a 40 kg/m³ density and 60% rebound rate, wrapped in 30mm thick medium-density foam across the back and arms, all covered in a matte black smooth woven performance fabric. Reinforced polyester stitching with 8mm seam pitch delivers 180 N seam tensile strength, while the upholstery holds a 50000 double rub abrasion resistance rating, and the swivel mechanism is rated for 30000 rotations. Functionally, the chair delivers 360-degree silent rotation with no tilt lock, centered on a fixed recessed bucket seat with no removable cushion. The continuous integrated armrests curve seamlessly into the enclosed backrest to provide targeted upper and mid-back support, ideal for extended seating. The stain-resistant smooth upholstery supports simple spot cleaning with a damp cloth, and assembly requires only minimal attachment of base glides with no complex hardware, taking an 40 minutes per set. This armchair fits a broad range of spaces: it works as standalone accent seating in residential living rooms or cozy home reading nooks, casual guest seating in office lounge and reception areas, sculptural seating in hotel lobbies and guest rooms, and comfortable customer perching in boutique retail and cafe spaces. It pairs well with 2.4 m executive desks in workplace settings. For procurement, note each unit ships in 2 cartons with a total packaged gross weight of 23 kg and 0.26 m³ carton volume, with 135 sets fitting a 20GP container at 85% space utilization. The chair supports a 136 kg static load capacity, with fixed dimensions including 470 mm seat height, 559 mm seat width at the narrowest point, and 762 mm base floor contact diameter for stable placement.
