Each detachable module of the curved sofa adopts an integrated upholstery structure covered in thick black fuzzy long-pile fabric with strong wear resistance and uniform fluffy texture, bringing enveloping soft touch for relaxation. The seat platform is filled with multi-layer composite high-density rebound foam, balancing sinking softness and lasting support to avoid long-term collapse, while reinforced multi-layer solid wood inner frame and full-coverage elastic webbing ensure stable load-bearing for daily heavy use. Ultra-small hidden metal feet are installed under each module to create a suspended visual effect without breaking the smooth curved outline, and matching fuzzy throw pillows of unified fabric are included for flexible back support adjustment. Clients can replace the fuzzy fabric with boucle, velvet or full-grain leather, and adjust the quantity and arc radian of modules to match different large-space layouts.
