[0002] The KR 10 2017 105 423 A discloses a chair that has a height-adjustable structure that provides the user with sufficient stability while sitting and at the same time supports a comfortable and correct sitting position.

[0003] There are currently a variety of different solutions for adjusting the height of seating furniture. The increasing number of height-adjustable tables in schools is driving the need for innovative and robust seating solutions. Disclosure of the invention

[0004] Embodiments of the invention can advantageously provide an improved piece of seating furniture. The invention is defined in the independent claims. Advantageous further developments of the invention emerge from the dependent claims and the following description.

[0005] An advantage of the seating furniture with the features of claim 1 is that by shifting the first support surface from a first orientation to a second orientation, a displacement of the first support surface along the first chair leg can be enabled. This eliminates the need for additional elements such as an electric height adjustment or the like. A further advantage is that the seat or the first support surface of the seating furniture can be specifically adapted to different people and groups of people.

[0006] This is achieved according to the invention in that the seating furniture has a first chair leg, a first adjustment unit and a first support surface. The first adjustment unit is designed to displaceably mount the first support surface along a first chair leg, wherein the first adjustment unit is designed to block a first displacement between the first support surface and the first chair leg by a first rotation of the first support surface into a first orientation of the first support surface, because the first adjustment unit is designed to release the first displacement between the first support surface and the first chair leg by a second rotation of the first support surface into a second orientation of the first support surface.

[0007] In other words, the piece of seating furniture can be a chair, in particular a chair for a school, which can be used in conjunction with a height-adjustable table. The first support surface can preferably be a seat plate or seat shell or similar. The adjustment unit can rotate the first support surface, in particular a seat shell or similar, relative to the first chair leg in order to lock and / or release a displacement between the adjustment unit and the chair leg. The first orientation of the first support surface is preferably an essentially orthogonal orientation of the first support surface to the direction of extension of the first chair leg. The second orientation is preferably an orientation of the first support surface substantially parallel to the chair leg.Essentially with regard to angle specifications in this embodiment, a tolerance of ± 25° includes, in particular, manufacturing-related tolerances. The seating furniture can thus preferably form a height-adjustable seat surface, in particular by means of the first support surface. The seating furniture can preferably also have a second support surface, which can be designed, for example, as a backrest that can be folded into a sitting position. The second support surface can be arranged on the seating furniture in both a height-adjustable and a non-height-adjustable manner. The contact of the adjustment unit with the chair leg is preferably designed such that, regardless of the first orientation or the second orientation, the first support surface does not slide down the first chair leg under its own weight. For this purpose, sliding elements can be provided, for example, between the adjustment unit and the first chair leg.
