The whole sofa set is wrapped in smooth dark grey full leather with delicate natural grain and excellent wear resistance, each independent modular unit crafted into uniform square block shape with neat segmented stitching to highlight geometric minimalist texture. Thick high-density rebound foam fills seat and back cushions, offering stable enveloping support that resists long-term sagging and deformation. Hidden tiny support feet maintain a streamlined floating outline without bulky exposed frames, while reinforced multi-layer solid wood inner frame with elastic webbing ensures reliable load-bearing capacity for daily heavy use. Customers can choose top-grain leather, microfiber leather or tech leather, adjust the quantity of seat and chaise modules, and customize the fabric tone of matching decorative pillows to fit various space design demands.
