Abstract: There is provided, in combination, a collapsible walker and a collapsible basket. The walker includes a pair of spaced-apart, operatively interconnected frame members. The frame members each have an upper end for placing one's hand and a lower end spaced-apart from the upper end. Ground-engaging wheels are rotatably mounted to the lower ends of the frame members. A folding mechanism allows the frame members to be brought together for folding the walker. The collapsible basket includes a pair of spaced-apart, rigid end members, each being connectable with a respective one of said frame members. A flexible basket member extends substantially about, extends between and is supported by the rigid end members. The end members are moveable towards each other and the basket member thereby folds to collapse the basket when folding the walker.
