A bed adjusted according to the vertebral curve of human includes groups of ascending and falling devices (1), one of which contains a base (11) which is provided with a height-sensing groove (12) and accommodating grooves (13) on the top. The height-sensing groove (12) is provided with a sensor (5) and the accommodating groove (13) is provided with a air canister (2) which is connected to a inflator (4) via pipes. The base(11) is provided with a plurality of elastomers(3) in which sensing sticks are placed. The sensor (5) connected to the inflator (4) and a control device (6) senses the dropping height of elastomers (3). The control device (6) receives signals from the sensor (5) so that the inflator (4) supplies gas to the air canister (2) to raise elastomers (3) to the desired height. |
