The sagepole high chair is continuously adjustable in height so that it can be optimally adapted to the environment. Its reduced and modern design is based on the form of a tree: the seat is enthroned on one single “tree trunk”, a solid wooden element, and four horizontally protruding feet resting on the floor provide stability. The sitting height is set along the central column via a screw fixture, without the need for additional tools; at any time a securing lock assures that the seat cannot accidently slip down.
