The present invention relates to a device for growing mushrooms, comprising a shelving, arranged for supporting beds for holding casing soil and compost on a pulling net, said beds for holding compost on a pulling net wherein the beds are placed at a mutual distance above each other wherein the beds are mutually movable, between at least a first position, wherein a second bed supported above a first bed at least partially impedes the accessibility of the first bed in a direction perpendicular to the plane in which the first bed extends; and a second position in which at least a larger part of the first bed is free approachable from a direction perpendicular to the plane in which the first bed extends than in the first position, wherein the displacement between the first and the second position requires a displacement of the first bed only, and wherein the device comprises a mechanic coupling between at least two beds, for moving the beds from the first position to the second position simultaneously.
