Abstract: An arrangement having at least one resting unit (B; Hyx) each having a lying/sitting surface (B1) and an actuator (A; A1 . . . ), configured to act on the lying/sitting surface, to adjust a height and/or firmness profile (V1, . . . ). An input value (KG), which corresponds to the standard size of an article of clothing representing a given person in a clothing size system is specified via at least one input unit (EE). A control device (S) derives a control signal (SL) from the input value and outputs the control signal to the actuator, so that the actuator autonomously presets a height/firmness profile, which is adapted to physical body parameters of the person represented by the clothing size, in the lying/sitting surface. A data network (DNi) enables the control unit to output control signals (SLyx) to the actuator of a resting unit (Hyx) selected for the person in such an arrangement.
