To provide a bed enabling a user to keep a comfortable posture by preventing the interference of surface materials spread on a back side frame and a waist side frame.
The bed provided with the back side frame 4 and the waist side frame 5, wherein the back side frame 4 is provided so as to be raised and brought down, has an erecting operation mechanism S1 for erecting the base end 4K of the back side frame 4 while elevating it. The erecting operation mechanism S1 is provided with a support rod 11 projected from the base end 4K of the back side frame 4 and a guide member 12 for guiding the side of the lower end 111 of the support rod 11. When the back side frame 4 is erected, since the side of the base end 4K of the back side frame is elevated, the back side frame 4 is lifted, the back side frame 4 and the waist side frame 5 do not interfere, and also a hornlike recessed part is not formed between the side of the base end 4K of the erected back side frame 4 and the waist side frame 5.
