Sofa Nomi is composed of a wooden carcass, fitted with metal nosag springs, topped with Bonell inner springs and HR cold foam. This is a high-quality filling that softens with use.

Depending on body weight and intensity of use, the padding and springing decreases in stiffness by 10% in the initial phase, eventually remaining constant at 85% of new value. In use, space will be created in the fabric which may cause slight creasing, this is normal.
