This Koinor Ronaldo sofa is a prime example of dynamic design and German engineering. Upholstered in timeless black leather, this two-seater exudes a powerful elegance, accentuated by the striking, wing-like shape of the armrests. We are particularly impressed by the visual lightness of the design: the sofa appears to float above the floor on its elegantly curved metal legs. The manual function of this two-seater refers to the flexible armrests: using a precise ratchet mechanism, they can be folded down in stages to transform them into a comfortable headrest for reclining. with its distinctive silhouette and elegant quilting on the backrest, the Koinor Ronaldo is a true design highlight, equally impressive as a standalone piece or as the centerpiece of a modern seating arrangement.
