The height-adjustable arm extends from the structural frame and is connected to the platform so that the platform can be positioned at varying heights. The platform provides workspace for the user by being attached to the at least one insert that can be, but is not limited to, a dish drying rack, a podium insert, or a house cleaner rack. The structural frame can be used for holding items such as boxes or cleaning supplies. The plurality of wheels allows the user to move the apparatus from one location to another. ## Claims ### Claim 1 A multipurpose mobile utility lifting ergonomic cart comprising: a structural frame; a platform; at least one insert; a plurality of wheels; a height-adjustable arm; a chute; a container; the structural frame comprising a first panel, a second panel and a plurality of legs; the first panel being terminally connected to the plurality of legs; the second panel being terminally connected to the plurality of legs opposite to the first panel; the height-adjustable arm being perpendicularly connected to the structural frame; the platform being terminally connected to the height-adjustable arm opposite to the structural frame; the at least one insert being removably attached to the platform opposite to the height-adjustable arm; the plurality of wheels being connected to the structural frame adjacent to the second panel and opposite to the plurality of legs; the height-adjustable arm comprising a guide, a bar and a locking mechanism; the guide extending vertically upward from the structural frame; the bar comprising a first end and a second end oppositely located to each other; the first end of the bar being slidably inserted into the guide; the platform being terminally connected with the second end of the bar; the locking mechanism comprising a rod, a braking device and a lever;
