The invention relates to a mattress (30) for a piece of sleeping or reclining furniture, having at least one sensor (12) arranged in the mattress (30) for sensing vibrations, motion, and/or sound. The mattress (30) is characterized in that the mattress has at least one element for receiving structure-borne sound, to which the at least one sensor (12) is coupled. The invention further relates to a piece of sleeping or reclining furniture, in particular a bed (1), having such a mattress (30).

The invention relates to an electric motor furniture drive for sleeping or reclining furniture, comprising a number of adjusting motors (7, 8) for moving at least one movable furniture component relative to an additional furniture component by means of an electric motor and comprising a manual operation unit (10) for operating the adjusting motors (7, 8). The electric motor furniture drive is characterized in that at least one sensor (12) is provided for detecting vibrations and/or sound, said sensor being coupleable to the sleeping furniture, and an analyzing unit is provided which is connected to the at least one sensor (12). The analyzing unit is designed to process and analyze the signals of the at least one sensor (12) and detect physiological parameters of a person using the sleeping or reclining furniture.

A non-transitory computer readable information recording medium stores an evaluation program for operating first and second motor control units, for evaluating operation characteristics related to a control device including a first motor control unit configured to control a first motor driving a first axis, and a second motor control unit configured to control a second motor driving a second axis. The evaluation program operates the first and second motor control units so that a shape of a movement path of a control target moved by the first and second axes includes at least a cornered shape in which both rotation directions of the first and second motors do not invert, and an arc shape in which one of the first and second motors rotates in one direction, and a rotation direction of the other of the first and second motors inverts.

A motor position control system includes a central server including first information of a first display device and second information of a second display device, and a motor position control device which controls positions of the plurality of motors, where the motor position control device includes a controller which receives the first and the second information from the central server and store the first and the second information in a memory, controls the positions of the plurality of motors based on the first information, calculates at least one value based on the first and the second information, selects at least some motors based on the at least one value, and controls positions of the at least some motors based on the at least one value.
