Product Description

The Cognac Vegan Suede Geometric Block Upholstered Lounge Armchair from JUESHANGDA, model BLK-LOUNGE-01, is a modern single-seat lounge chair defined by sharp geometric form and clean, integrated construction. Its monolithic block silhouette features a fixed offset upright backrest set at a 10-degree backward recline from vertical, with a deliberate open gap between the back and one wide, padded armrest that sits flush with the chair’s integrated block leg supports, creating a streamlined, sculptural visual presence. The 1.2mm cognac matte vegan suede tech fabric upholstery covers all structural elements, including the integrated legs, with matching-color polyester thread forming clean, straight seam details at 8 stitches per inch for a tailored, cohesive finish. Non-marking, non-slip plastic glides sit at the base of each leg to preserve floor surfaces without disrupting the chair’s smooth, unbroken profile. Beneath the upholstery, the frame combines solid kiln-dried pine with 18mm curved plywood reinforcement, supported by a 14mm bent plywood internal seat board. The 150mm thick seat cushion uses 40kg/m³ CMHR polyurethane foam wrapped in 200g polyester fiber, while the 120mm thick backrest uses 22kg/m³ high-resilience polyurethane foam wrapped in the same 200g polyester fiber, delivering a 60% foam rebound rate for balanced comfort. Armrests feature a 40kg/m³ polyurethane foam core over the wood frame for soft, supportive contact. The fixed stationary base includes no swivel, recline, or tilt mechanisms, and the chair holds a static weight capacity of 136kg with a frame static load rating of 272kg, with no loose removable cushions for long-term structural stability. Overall dimensions measure 870 x 750 x 780 mm, with a 450mm seat height, 720mm seat width, 600mm seat depth, and 610mm armrest height. This lounge chair fits a broad range of public and private spaces. It works as a standalone accent piece next to sofas or coffee tables in residential living rooms, a dedicated seat in home reading nooks positioned near windows or bookshelves, supplementary seating at bedroom vanities or bed feet, modern guest seating in office breakout and reception areas, and curated seating in boutique hotel lobbies, cafes, and co-working lounges. It pairs best with low-profile coffee tables and minimalist side tables at 450mm height. For procurement, note each unit ships in 2 cartons with 40 minutes of required assembly per set, and a 20GP container holds 135 sets at 85% space utilization, suitable for bulk furnishing projects.
