The Mustard Fully Upholstered Monolithic Lounge Armchair with Block Base, model LNG-ARM-MST-01, is an unbranded contemporary single-seat lounge seating solution designed for flexible use across residential and commercial settings. Its visual identity centers on a cohesive, soft-edged monolithic form defined by a seamless curved transition from armrests to backrest, accented by a low open cutout on the side panel. It features a legless, fully wrapped block base that rests directly on the floor for a grounded, streamlined profile, with precision stitched fabric binding trimming all edges for a polished, tailored finish. Crafted for durable daily use, the chair builds on a core structure of 25mm thick kiln-dried solid pine internal framing, supported by 14mm bent plywood seat support boards and 12mm thick engineered wood side panels. The seat uses 80mm wide elastic webbing for suspension, topped with a 240mm thick cushion of high-density polyurethane foam wrapped in dacron, paired with medium-density polyurethane foam fill for the backrest. All surfaces are upholstered in matte woven polyester fabric with a stain-resistant finish, secured with even 3 stitches per centimeter seam construction. The upholstery delivers 50000 double rubs of abrasion resistance, while 5mm thick non-scuff nylon glides line the base to protect floor surfaces, with a full-perimeter floor contact design for even weight distribution. The fixed non-reclining structure supports a maximum static weight of 136kg, with balanced seat proportions and gently angled support for extended sitting comfort. This armchair works as a standalone accent piece or paired with a coordinating side table, suited for residential living rooms, office lobbies, hotel reception areas, open office casual collaboration zones, and clinic, salon, or retail waiting spaces. It is compatible with tile, hardwood, and low-pile carpet flooring. Procurement teams should note each unit ships in two cartons, requires 40 minutes of assembly per set, and supports efficient bulk loading for large-scale projects. The 20kg net weight design allows for flexible repositioning as space needs evolve, without sacrificing structural stability for regular high-traffic use.
