Seating furniture

A piece of seating furniture, particularly a chair with a resilient frame which, from the side view, is substantially configured Z-shaped and which comprises an upper part of the frame, two lower parts of the frame and two middle parts of the frame, each connecting a lower part of the frame with the upper part of the frame, wherein

• the upper part of the frame reaches from a rear area of a seat surface which can be arranged to the upper part of the frame to a front area of the seat surface,
• the lower parts of the frame form skids at least partially running parallel to the seat surface and from the front area of the seat surface to the rear area of the seat surface,
• the middle parts of the frame each reach from the respective lower part of the frame in the rear area of the seat surface upwards at an angle to the upper part of the frame in the front area of the seat surface, and
• the distance of the middle parts of the frame to one another at the upper part of the frame is up to a maximum of half, of the width of the seat surface in the front area in order to at least partially enable a lateral, ergonomically advantageous movement of the upper part of the frame with regard to the lower parts of the frame when using the piece of seating furniture, without the lower parts of the frame considerably lifting off the ground.
