This relates to a mattress designed angle adjustment. The subject innovation is a rectangular frame shape and the lower frame Is installed on the lower surface of the one side edge has a long hole in the inner fixed guide and the lower frame all around the corners of the frame and the lower supporting member having a screw shaft so as to adjust the vertical height of the lower frame It formed in a rectangular frame shape, and the one-side end portion in contact with the outer surface of the guide and rotated with the long hole of the guide frame chukseol a pin Chukseol and a pin on either side end region of the pivoting frame so as to support the lower frame and the pivoting frame, and the pivot link is chukseol inside both sides of the intermediate region of the lower frame as a pin And the rest one-side adhered to the lower surface of the lower base, and a piston that is driven by the lower surface of the actuator and the actuator is chukseol to the base And a support piece for connecting the end of the piston pin is secured to the horizontal frame of the rotating frame It is provided on the horizontal frame and the signal of the power supply and remote control which is characterized in that it comprises a control box to signal to the actuator. As a result, just adopting the small power of a relatively simple configuration and to increase the rotational angle of the mattress to a desired only the piston the length of one of the actuators at the same time and can be quickly and to control easily the angle of the mattress is placed for various bed or floor, the mattress angle The control can regulate a plurality of angle installation as the upper and lower body is placed mattress as needed individually or at the same time, batchineun the mattress angle adjuster the mattress bed frame or effects that can for example also use them on the floor instead of a bed There is. And this devise is, the economic advantage because the existing user who can easily fixed by instal
