Upholstered soft surface adopts full black top-grain genuine leather with natural grain texture, excellent scratch resistance and breathable performance, each independent seat module can be separated and freely combined to match various space layouts. Multi-layer thickened seat and back cushions are filled with high-density rebound foam, maintaining stable supportive softness and resisting long-term compression sagging; square oversized solid side armrests perfectly echo the cubic design language, paired with two matching leather leaning cushions to enrich the layered sense. The bottom of all modules is equipped with seamless polished chrome metal base trim, replacing exposed thin legs to create a stable low-profile visual effect. The built-in frame uses reinforced multi-layer solid wood, and leather covers can be partially disassembled for local maintenance; alternative materials including semi-aniline leather and microfiber leather are available for wholesale and engineering clients.
