The inside of the backrest is shaped and inclined for greater comfort.
The long, enveloping shape of the backrest also gives support to the arms, for a more relaxed seat.
No screws, only purity lines.
The perfection of a circle and the straightforward geometries can be enhanced only by the cleanliness of the elements.
