This invention belongs to the field of stool technology, specifically relating to a height-adjustable stool for assisting standing, comprising: a Y-shaped base including three supporting arms; the upper surface of each supporting arm is a supporting plane; chamfered edges are present on opposite sides of the supporting plane; the width of the extended end of the supporting plane is greater than the width at its base; a base; and a support
assembly including a movable rod and a fixed sleeve; the movable rod is movably mounted on the fixed sleeve; the upper end of the movable rod is connected to a connection port at the center of the Y-shaped base, and the lower end of the fixed sleeve is fixedly connected to the base. The height-adjustable stool in this design allows for
straddle use and height adjustment as needed, assisting workers who stand for long periods, alleviating
lower limb swelling and
varicose veins; when made of
metal, it is more robust and durable, and absorbs
static electricity. Height control is unnecessary, reducing bacterial transmission and cross-infection among mobile users.
