The Sculptural Three-Tone Upholstered Wave Lounge Chair is an unbranded upholstered lounge seat with a relaxed, organic profile. Model WAVE-LNG-920-900, it measures 850 by 920 by 900 millimeters and presents a layered wave form defined by a yellow seat and back, an off-white middle band, and an orange floor-contact base. The armless silhouette uses tailored stitched seams that follow the curved transition between seat and back, giving the chair a sculptural, floor-connected appearance rather than a conventional leg-supported look. Construction combines soft woven upholstery with a layered padded shell and a hidden internal support frame. The yellow seat and back use a fine woven textile fitted tightly over curved foam. The contrasting off-white middle layer is a shaped woven band, while the orange base is upholstered in durable woven textile over a load-bearing padded form. Seat cushioning consists of 120 millimeter polyurethane foam with integrated contouring and 35 kg/m3 compression resistance; the inclined back uses 100 millimeter layered polyurethane foam rated at 30 kg/m3. The upholstery fabric weighs 380 g/m2. Beneath the padding is an 18 millimeter molded plywood or equivalent curved composite structural shell, reinforced by a 25 millimeter tubular steel or bent hardwood frame. Non-marking fabric or felt glide pads protect floor-contact zones. Designed for a fixed lounge posture, the chair has a 380 millimeter seat height and a 118-degree inclined back. Its raised 160 millimeter side and front lip helps cradle the thighs and lower back, while the integrated raised side edges offer partial arm support without separate armrests. The arched floor profile permits gentle fore-and-aft rocking through a 7-degree arc. There is no swivel, height adjustment, or mechanical recline, preserving the clean alignment of the upholstered shell and base. The seat is 680 millimeters wide and 620 millimeters deep, with a 520 millimeter backrest above the seat. Net weight is 18 kilograms, with a recommended static user load of 136 kilograms. The chair is suited to design-led hotel lobbies, showrooms, creative office breakout areas, residential living rooms, concept stores, exhibition displays, furniture galleries, and premium relaxation corners. It works best as an accent seat where visual identity and relaxed comfort take priority over dense, task-oriented seating. For procurement, note that each set ships in two cartons, with packaged gross weight of 23 kilograms, carton dimensions of 850 by 420 by 720 millimeters, and reference assembly time of 40 minutes.
