The most relevant technical/aesthetic novelty of this article is the use of passive caterpillar belts which effortlessly glide downstairs, with an elevated level of security. Careful examination of the whole chair reveals a seat that has been very carefully studied; aesthetically and in its conceptually free styling. The mixture of technical requirements give it an aggressive style. For example the tortuous conformation of the welded frame or the obvious originality of the seating posture. The precocity of the aesthetics is underlined by the distribution of the angles, the backrest that can be telescopically inclined, the adjustable headrest and the handles for transportation that can also be detached from the chair itself. Innovative design and the maximum of security possible when in use, make the new Skid Series an absolute novelty within the environment of evacuation and transport.
