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, wherein the beds are placed at a mutual distance above each other;characterized in that 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, wherein there is at least a free zone of 40 centimeter in said perpendicular direction, and wherein the movement between the first and the second position comprises both a translation, in particular in a width direction, and a rotation of the bed.
