Abstract
In a multifunctional bed in which a variable bed that can be changed into a wheelchair form is fitted in a U-shaped fixed bed, when a seat back portion of the variable bed is laid or raised, the variable bed may assume an unstable position, thus hindering a smooth form change. The present invention provides a multifunctional bed comprising a variable bed that can be changed into a wheelchair form and a fixed bed in which the variable bed can be removably fitted, wherein a holding member is provided between the fixed bed and the variable bed for holding a vertical position of the variable bed relative to the fixed bed and the holding member comprises a vertical pair of guide rails disposed on a left and right inner side surfaces of a notched recess portion of the fixed bed formed so as to appear substantially U-shaped, and guide rollers disposed on both sides of a seat back portion of the variable bed
