The entire sofa set is upholstered in smooth full black leather with delicate natural texture and excellent wear resistance, every independent module crafted into uniform square block shape with clean stitching on all edges to highlight minimalist geometric beauty. Thick integrated high-density foam fills seat and back cushions, offering stable enveloping support without deformation after long-term sitting. The hidden tiny foot design keeps the overall silhouette low and streamlined, eliminating cumbersome exposed frames. The internal framework is built with sturdy multi-layer solid wood and elastic webbing for reliable load-bearing; customers can choose top-grain leather, microfiber leather or tech leather, adjust the quantity of seat and chaise modules, and swap decorative pillow fabrics and colors to meet various space design demands.
