The Yiankang LC-BW4S-001 armless high-back bentwood shell swivel lounge chair features a streamlined, minimalist silhouette defined by its continuous curved seat and back shell, paired with a polished flat 4-star metal base. The open armless layout creates unobstructed access from the front and both sides, while the tall backrest delivers structured upper body support for relaxed, slightly reclined seating. Constructed around a 12mm thick bent plywood structural shell finished with walnut veneer, the chair uses differentiated foam densities for balanced comfort: a 45 kg/m³ high-density polyurethane seat core and 35 kg/m³ medium-density polyurethane back core, both wrapped in smooth dark charcoal 1.2mm polyurethane faux leather upholstery secured with color-matched high-tenacity polyester double stitching. The central support stem and 4-star base are crafted from polished chrome-plated steel, fitted with felt-tipped non-scuff glides at each prong end to protect hard flooring surfaces. A heavy-duty steel ball bearing assembly enables full 360-degree swivel rotation with passive return-to-center alignment, with no adjustable height, tilt, or lock mechanisms, and no rolling casters, keeping the chair in stable fixed positioning. The fixed 18-degree reclined back angle supports casual, relaxed posture suited to non-task use, and the non-porous upholstery allows simple spot cleaning with mild detergent, with flush seams that reduce dust trapping. This lounge chair suits a broad range of commercial and residential spaces, including corporate office reception and waiting areas, hotel lobbies and guest room lounge zones, co-working breakout spaces, design showroom displays, executive office informal meeting areas, as well as modern residential living rooms and home studies. Its compact form and warm walnut-and-dark upholstery palette complement mid-century and contemporary interior schemes, while the armless design supports efficient seating density in high-traffic public zones. For procurement, teams should note the chair ships in knock-down format requiring simple on-site attachment of the base to the pre-assembled seat shell, with standard export packaging to prevent transit damage. Buyers should confirm final material specifications for core wood species, upholstery grade, and alternative base material options directly with the supplier, as standard configurations may offer upgraded leather upholstery or polished aluminum base variants. The chair’s contract-grade abrasion resistance and static load rating support regular daily use in both light commercial and residential settings.
