This invention relates to a method of controlling the lifting of bottom sections of lying furniture such as a bed. It is a method of controlling the lifting of bottom sections of lying furniture such as a bed that has a back bottom section for lifting the back portion of a lying person and a knee bottom section for lifting his/her knee portion, in which the respective bottom sections can be lifted by the lifting mechanisms respectively provided for them, characterized in that in the case where all the bottom sections are lowered to lie flat from a state where the back bottom section is kept inclined after having been pivotally rotated and lifted, at first the lifting of the knee bottom section is started, and at a time instant adequately later than the lifting start time instant, the lowering of the back bottom section is started; thereafter the lowering of the back bottom section is continued, while the knee bottom section is lifted to the preset highest position and then is lowered to reach its lower limit position of lying flat at a time instant adequately later than the time instant when the back bottom section is lowered to its lower limit position of lying flat.
