Product Description

The Two-Tone Curved Shell Swivel Lounge Chair, model SWL-4PRG-001, is an unbranded modern lounge seating piece defined by a smooth, continuous curved shell form that integrates armrests, seat, and backrest into a single cohesive silhouette. Its two-tone upholstery pairs woven polyester blend fabric on the seat and inner arm surfaces with matte tan synthetic leather on the outer back shell, accented by matching light gray piping along seam edges for a polished, tailored finish. It is supported by a four-prong polished chrome-plated steel star base with a wide, stable span, creating a balanced visual contrast between the soft upholstered upper and sleek metallic lower structure. Built for durable, long-term use, the chair’s inner seat frame is constructed from kiln-dried plywood, lined with high-density polyurethane foam cushioning for consistent support. The polished chrome-plated steel central stem connects to a lubricated steel bearing assembly that enables smooth operation, while non-scratch felt glides pre-installed at each prong end protect hard flooring surfaces from scuffs and abrasion. All seams are stitched to a consistent 8 stitches per inch, and upholstery is rated to withstand 50000 double rubs for resistance to regular wear. The chair supports full 360-degree rotation around its central stem, with a fixed 110-degree reclined lounge angle optimized for relaxed seating; it includes no height, tilt, or recline adjustments, and its stationary base is fitted without casters for stable placement. The fixed seat height and dimensioned seat and backrest are engineered to support comfortable upright-relaxed postures, with a recommended static load capacity of 136 kg for broad user suitability. This chair fits a wide range of commercial and residential spaces: it serves as polished guest seating for office reception areas, high-end hotel lobbies, and executive break rooms, works as a casual collaborative seating option for open office zones, functions as an accent piece for residential living rooms, reading nooks, and quiet solo focus corners, and acts as a design-forward display seating option for modern showrooms and galleries. It comes with a 3-year warranty, requires 40 minutes of assembly to connect the base to the seat stem with included fasteners, and ships across two cartons per set. Procurement teams should note assembly labor requirements, total packaged volume for freight planning, and load capacity to align with intended use case demands.
