Abstract: A walker is made adjustable for various sizes of persons, including grossly obese persons. The walker includes two side support members, each of which has a front leg, a back leg, and a cross leg connecting the two legs. A braced sleeve assembly is positioned on the front leg of each side support member. The braced sleeve assembly has an elongated first sleeve dimensioned to slide over the front leg, an elongated second sleeve extending horizontally and inwardly from the elongated first sleeve, and a support brace extending at an angle from one sleeve to the other sleeve. The second sleeve has a set of spaced positioning holes. A releasable latch is mounted to the elongated first sleeve. The walker further includes a cross bar dimensioned to slide inside the second sleeves of the braced sleeve assemblies.
