The 3angle armchair and two-seater sofa is a result of mindful and persistent product development that prostoria grants to its designers. Following a competition in 2011, the project has undergone a number of transformations tested on prototypes while simultaneously preserving the original design idea. Fragmented, crystal-like forms systematically describing a compact volume, almost like an algorithm, characterize the design. This solution is not only formal - the characteristic 3angle armrests follow the ergonomic line of relaxed arms. A soft shell of the backrest and armrest is covered with a continuous cover whose edges are marked only with a very subtle line of seams. A light metal sub-construction reproduces the characteristic triangular motif contributing to the compactness of the composition. The 3angle is a self-confident yet very disciplined formal step forward whose strong identity does not interfere with fitting in various ambiences.
