Element sofa Vita is constructed of a wooden carcass, fitted with metal nosag springs. On top is a Bonell inner spring with HR cold foam and memory foam. Vita's seating comfort differs from other By SIDDE sofas, as Vita uses a top layer of memory foam. This allows the seat to form itself to your body.

Depending on body weight and intensity of use, the padding and springing decreases in stiffness by 10% in the initial phase, eventually staying constant at 85% of new value. Fabric Chess is a stretchy fabric, which is necessary because of the round shapes of the model. In use, the fabric moulds itself and space will be created. Where you sit, the fabric will bend slightly, which is part of the model.
