The JUESHANGDA Mid-Century Modern Mustard Fabric Wingback Lounge Armchair (model LC-WG-MST-001) balances timeless mid-century design cues with robust, user-centric construction for both residential and commercial public seating applications. Visually, the chair features a signature wingback silhouette defined by a smoothly curved bent plywood outer shell finished in dark walnut stain, paired with tapered, splayed solid rubberwood legs in a dark espresso finish, upholstered in warm mustard yellow woven polyester blend tech fabric. Its fixed four-leg base sits at a 12-degree outward splay to create a stable footprint, with integrated curved armrests formed directly by the bent wood shell, capped with padded top surfaces for comfort, and a central recessed lumbar detail on the ergonomic backrest. Precise upholstery with 8 stitches per 30mm seam pitch is secured to the inner shell with hidden staples for a clean, tailored finish. Construction centers on an internal support frame of 18mm thick kiln-dried solid hardwood and plywood, paired with a 4mm thick sinuous zig-zag spring and polypropylene webbing seat support system. Cushions use high-density 50 kg/m³ polyurethane foam wrapped in 200g polyester fiber, with a 120mm thick seat and 80mm thick backrest; the removable loose seat cushion simplifies cleaning and regular rotation to extend service life. The upholstery achieves 30000 Martindale abrasion cycles, while the frame holds a 200kg static load rating and the chair supports a 150kg user weight. All legs are fitted with 8mm felt glides to reduce movement noise and prevent scuffing to hard floor surfaces. Fixed stationary construction includes no swivel, recline, or rocking mechanisms for consistent, stable seating. The chair fits a range of spaces: it works as a standalone accent seat for residential living rooms, dedicated home reading nooks, office breakout and waiting zones, boutique hotel lobbies, and restaurant waiting areas, and can be deployed in matched pairs to form symmetrical conversation seating. It pairs ideally with 450mm height round side tables, minimal floor lamps, and low-pile area rugs. For procurement, note that leg attachment is required on receipt, with included hardware and hex key supporting a 40-minute assembly time per unit; each chair ships in two cartons, with 135 units fitting a 20GP container at 85% space utilization for efficient large-scale ordering.
