Ndesign named this special sofa SECRET, which they reached as a result of their knowledge and experience in seating culture. Instead of expecting the individual to adapt to the design, it is aimed to “adapt the product to the user” with the form and material design, especially in the seat and back. Designed to provide maximum comfort to the space, the simple form is presented to the user as a cover for the function in the Secret sofa. The angular surfaces where the seat and back come into contact provide a natural resting position between the spine and legs, while flexible memory materials that can absorb the variability of dynamic movements during sitting are used between the upholstery and the frame.
