In another embodiment, walker comprises a structural frame with a first end, a second end, and sides between the first end and the second end, a handle or handles on the structural frame at the first end of the structural frame, ground engaging elements at the first end and the second end of the structural frame, and a suspension system integrated with the structural frame.

Claims (31)

1. A walker having a folded position and an unfolded position, the walker comprising:

a structural frame with a first upright portion, a second upright portion, a folding mechanism between the first upright portion and the second upright portion, and ground engaging elements on each of the first upright portion and second upright portion; and

a foldable basket with first and second opposed ends secured by one or more fasteners to the first upright portion and the second upright portion, respectively, to prevent the foldable basket from being removed by the user during use, in which the one or more fasteners comprise fasteners that:

are threaded to a part and must be unthreaded from the part to disassemble the fastener to disconnect the foldable basket from the first upright portion and the second upright portion.
