A foldable walker includes upstanding legs arranged in a generally square pattern, each of which is capped by a fixed joint member and each of which has a slider member slideably disposed on it. Two forward legs are interconnected by two rigid links arranged in a scissors arrangement with the uppermost end of each link pivotally connected to a fixed joint member and the lowermost end of each link pivotally connected to a slider. Each forward leg is interconnected to its associated rearward leg in the same way. Each pair of rigid links is interconnected to one another by a pivot pin. The linkage enables the width and the depth of the walker to be reduced to a very small space and telescoping legs reduce the height dimension of the walker. Handles are folded when the walker is stored and pivoted into their operable position when the walker is deployed.
