Zusammenfassung:PROBLEM TO BE SOLVED: To provide a user-support apparatus which allows a user supported on the user-support apparatus and/or a caregiver to know the height of an upper frame with respect to a floor. SOLUTION: The user-support apparatus includes a lower frame, a support, the upper frame, and a light source. The support is coupled to the lower frame. The upper frame is movably supported above the lower frame by the support. The light source is configured to selectively emit light at one of a first wavelength and a second wavelength as a function of the height of the upper frame with respect to a reference point in order to indicate the height of the upper frame.
