The present invention relates to a control method using the gravity of functional bed, the mattress of the bed and a given time is one to minimize the gravity of human body skin aging prevention and varicose veins, or may be helpful in the treatment of circulatory diseases such as hypertension inclined by a predetermined angle. bed method of the present invention, the function control of a controller an operation setting step for setting the tilting angle and rhythm, including the motion-pattern inclined by a setting unit, the operation when the rhythm is set to wait until the standby operation start signal is given from the controller step, the user operates the standby step the tilting operation of operating means for controlling the time from when entering the deep sleep state, a separate input signal is not tilted tilting the bed according to the set operating angle rhythm to the controller until it reaches a deep sleep time set by initiation step, the set time is exceeded when the deep-sleep stage includes a complete stopping of the tilting means, and has a different tilt angle according to the users body weight was recognized from the weight sensor, surface recognition sensor to identify the user and the motion of the pupil from the surface of the water, depending on whether or not the recognized user determines whether the entry of the initial operating stage, wherein the controller is a new time from the beginning to reach the deep sleep time when a new signal is input to the previously set time is reached the deep sleep and counting, the operation initiation step comprises a deep-sleep and deep sleep time if having a valence state surface having a valence state, which is tilted by the tilting motion rhythm singer surface means in the time from the deep sleep time tiltang set to different rhythms and behavior that is tilted by means.본 발명은 중력을 이용한 기능성 침대의 제어방법에 관한 것으로, 침대의 매트리스가 소정시간 및 소정 각도로 기울어지게 함으로써 중력작용을 최소화시켜 인체의 피부노화를 방지하고 하지 정맥류나 고혈압 등의 순환계 질환 치료에 도움이
