The present invention concerns a bed (1) provided with a device (2) suitable for facilitating the straightening of blankets and sheets when making the bed. Said device (2) is of the type with a frame, or surround, comprising two rods (2a, 2b) and a third transverse rod (2c) which joins the second ends of said two rods (2a, 2b), capable of rotating around an axis (4) from a horizontal to a vertical position and vice versa, the axis of rotation (4) being horizontal, transverse with respect to the length of the bed and situated in the vicinity of the head (5) of the bed; means are provided suitable for hooking the covers (7) in the highest position of the frame, i.e. to said third transverse rod (2c) of said frame, when the latter is in the vertical position, said device (2) being characterized in that a further two short additional rods (2d, 2e) are provided, connected to the ends of said transverse rod of the frame, said additional rods (2d, 2e) being able, in turn, to assume a first position when said rods (2d, 2e) are aligned with said transverse rod (2c) so as to constitute an extension of said transverse rod (2c) suitable for gripping the part of said cover (7) exceeding the width of the mattress of said bed (1).
