While the outside lines of NUBE armchair are made of flat parallel surfaces, the space where we can sit is curved and cosy, like a nest. Instead of a solid block, the design of NUBE allows to see all the back part of the armchair. So the shape with all the curves where we are going to sit is visible. Looking at the armchair, before seating, we can already expect a big comfort from the armchair. The volume is then delimited by the sober straight lines of the outside, enriched by the grace of the inner curves
