ABSTRACT:
A healthy bed for actively supporting a human spine curve mainly comprises a lower base, a plurality of mobilizing devices inside the lower base, a height sensor, a control device, and an inflating device; an upper mattress having an air cushion layer and a plurality of push rods; wherein the control device is used for memorizing the spine curve of a person lying on the upper mattress. When a user lies on the upper mattress, the push rods is are pressed to push the mobilizing devices to move downward, the height sensor detects a moving distance of the mobilizing devices for the control device to determine whether the user is the one whose spine curve is memorized, and if so, then the inflating device is activated to inflate the air cushion layer to let the surface of the upper mattress meet the profile of the spine curve of the user.
