The seat cushion is made of foam rubber and wood: an organic material whose warm tones help create a homely atmosphere that inspires hospitality and serenity. The pivot of the system is constitued by the central column, formed by “vertebrae” connected to each other through bands os springs. The modular and elastic structure makes this product unique: it is able to support the user but also to give him the freedom of movement. In conclusion, it is possible to adjust the tension of the double blades positioned under the seat to obtain a more enveloping seat.
