You’ve all seen this before: tennis balls on a walker. In fact, Google walker tennis balls and you’ll get 329,000 results. The first three: How to Make a Walker Glide Most Easily, CWI Medical’s Walker Tennis Balls, and a blog post Tennis Balls and Walker, an Ultimate User Hack.
If the manufacturers of adult walkers ever took a moment to actually observe people using their product, they’d realize that every geriatric in the known universe has tennis balls on the back legs of their walkers to make them slide instead of having to keep picking them up with each step. It’s such a popular solution that medical companies sell pre-cut tennis balls that easily fit!
Other products that remind me of walker tennis balls:
The chip clip
The iPod case
These are products that are widely sold solely because the products with which they are used are somehow deficient. Isn’t it amazing that the original products haven’t been improved to resolve the problem?
What others can you think of?
