A folding bed module (3, 3.1, 3.2) for a modular folding bed system comprising a base frame (5, 5.1, 5.2) which is supported on a floor and comprising a bed structure (6, 6.1, 6.2) which is encompassed by the base frame (5, 5.1, 5.2) in a head end and is held thereon in a pivotable manner via at least one pivot fitting with a pivot axis oriented in a horizontal width direction, said bed structure having two longitudinally extended longitudinal carriers which are held opposite one another in an aligned manner with respect to the width direction and are connected via a transverse carrier, wherein the bed structure (6, 6.1, 6.2) can be moved from a non-use position, in which the bed structure (6, 6.1, 6.2) extends vertically and is propped up on the base frame (5, 5.1, 5.2), into a use position, in which the bed structure (6, 6.1, 6.2) extends horizontally and is pivoted out with a foot end opposite the head end towards a front side and is propped up on the base frame (5, 5.1, 5.2) in any case in the region of the head end, and back, wherein the base frame (5, 5.1, 5.2) has two console carriers of equal length which are arranged in an aligned manner with respect to one another and with respect to the width direction at the level of the longitudinal carriers or preferably between the longitudinal carriers of the bed structure (6, 6.1, 6.2) and on which the bed structure (6, 6.1, 6.2) is propped up in any case in the region of the head end, wherein the base frame (5, 5.1, 5.2) has two side plates which are opposite one another in an aligned manner with respect to the width direction and extend in a planar manner in a horizontal longitudinal direction oriented perpendicularly to the width direction, wherein the console carriers are arranged between the side plates with respect to the width direction, wherein the console carriers project vertically beyond the side plates in such a manner that the pivot fittings are arranged above the side plates, characterized in that the base frame (5, 5.1, 5.2) has two two-legged corner brackets with a vertically extended first leg (38.1) and with a second leg (38.2) which is oriented at right angles to the first leg (38.1) and extends horizontally and faces the floor, the console carriers being supported on the second legs (38.2) of the corner brackets and connected thereto, and the legs (38.1, 38.2) in each case abutting the side plates and being connected thereto in such a manner that the side plates and the corner brackets in each case form a bracket console, and the bracket consoles and preferably the second legs (38.2) of the corner brackets of the bracket consoles being connected to one another via a transverse connecting element which extends longitudinally in the width direction, in particular a transverse connecting carrier and/or a transverse connecting frame and/or a transverse connecting plate. a base frame (5, 5.1, 5.2) which is supported on a floor and comprising a bed structure (6, 6.1, 6.2) which is encompassed by the base frame (5, 5.1, 5.2) in a head end and is held thereon in a pivotable manner via at least one pivot fitting with a pivot axis oriented in a horizontal width direction, said bed structure having two longitudinally extended longitudinal carriers which are held opposite one another in an aligned manner with respect to the width direction and are connected via a transverse carrier, wherein the bed structure (6, 6.1, 6.2) can be moved from a non-use position, in which the bed structure (6, 6.1, 6.2) extends vertically and is propped up on the base frame (5, 5.1, 5.2), into a use position, in which the bed structure (6, 6.1, 6.2) extends horizontally and is pivoted out with a foot end opposite the head end towards a front side and is propped up on the base frame (5, 5.1, 5.2) in any case in the region of the head end, and back, wherein the base frame (5, 5.1, 5.2) has two console carriers of equal length which are arranged in an aligned manner with respect to one another and with respect to the width direction at the level of the longitudinal carriers or preferably between the longitudinal carriers of the bed structure (6, 6.1, 6.2) and on which the bed structure (6, 6.1, 6.2) is propped up in any case in the region of the head end, wherein the base frame (5, 5.1, 5.2) has two side plates which are opposite one another in an aligned manner with respect to the width direction and extend in a planar manner in a horizontal longitudinal direction oriented perpendicularly to the width direction, wherein the console carriers are arranged between the side plates with respect to the width direction, wherein the console carriers project vertically beyond the side plates in such a manner that the pivot fittings are arranged above the side plates, characterized in that the base frame (5, 5.1, 5.2) has two two-legged corner brackets with a vertically extended first leg (38.1) and with a second leg (38.2) which is oriented at right angles to the first leg (38.1) and extends horizontally and faces the floor, the console carriers being supported on the second legs (38.2) of the corner brackets and connected thereto, and the legs (38.1, 38.2) in each case abutting the side plates and being connected thereto in such a manner that the side plates and the corner brackets in each case form a bracket console, and the bracket consoles and preferably the second legs (38.2) of the corner brackets of the bracket consoles being connected to one another via a transverse connecting element which extends longitudinally in the width direction, in particular a transverse connecting carrier and/or a transverse connecting frame and/or a transverse connecting plate.
