| Start here. This has many of your ideas already incorporated. Forget the springs in the legs -- hazardous. Forget the cup-holder, too. Many/most walker users have other problems going on, too.

Build on what's already been done. And be aware the marketplace is incredibly diverse as far as what's beneficial and what isn't from user-to-user. |
