摘要: An electrically adjustable piece of furniture comprises a first and at least one second actuator for adjusting a component of the piece of furniture and a controller for controlling the first and at least one second actuator. The actuators each have a first element and a second element which are displaceable relative to each other, and a sensor attached to the first element and adapted to measure a distance between the first and second elements. The distance measurement is based on a time-of-flight measurement of a wave. The controller is arranged to determine an absolute position of each actuator from the respectively measured distance.
