The disclosure demonstrates a collapsible wheeled walker having two side frames supported above a walking surface with attached wheel assemblies. The side frames are interconnected by an X-folder apparatus. The X-folder apparatus has first and second elongate elements rotatably coupled to each other with the bottom ends of the elements rotatably attached to the bottoms of the side frames, and the top ends of the elements having perpendicular support elements that in the deployed open position, engage support brackets formed on the inner sides of the side frames. The support brackets have protrusions extending from bracket support surfaces to engage complementary apertures formed in the perpendicular support elements to provide stability to the wheeled walker.

Wheeled walker

A collapsible wheeled walker with two side frames and two height adjustable upper body supports. The apparatus includes a seat that is slidably attached to the two side frames and is movable between a front position to facilitate an ample walking space inside the frames and a rear position for a user to sit. The apparatus may include an X-folder that facilitates collapsing the walker to a small footprint for storage and transportation. It may also include a left forearm gutter and a right forearm gutter as part of the upper body supports that give the user an upright walking posture for health benefits.
