Furniture, in particular seating furniture

Abstract

Piece of furniture includes a first part, and a second part that may be adjusted relative to the first part of the piece of furniture in an adjustment movement. There is a drive device, the drive device being configured for adjusting the second part relative to the first part. At least two drive units are allocated to the second part. In a first kinematic phase of the adjustment movement, the adjustment is carried out by use of a first drive unit, and in a second kinematic phase of the adjustment movement the adjustment is carried out by of a second drive unit, the second part moving relative to the first part in the first kinematic phase and carrying out a substantially equivalent adjustment movement in the second kinematic phase.
