Alias Armchair on casters White Plastic material. Dimensions: W 59 cm x D 56 cm x H 77 to 87 cm – Seat H 44 to 54 cm. Segesta is a multipurpose chair. The use of a new plastic technology Hirek© and the strong character of the design, combined with the flexibility of the back rest and its stackability, are the basis for the enormous success of this chair. The length of the armrest was intentional so it would fit well at a dining table or serve as a more relaxed armchair. The multiplicity of its use is nearly endless, and the variety of the support frames adds even more possibilities.
