Dinners,
you get your feet ont' one of these things and pretend you are going somewhere's. But you don't. Sound familiar? Easier on the knees these, than walking. I am more familiar with the Clothes Hanger Helper Model 3. Comes in handy when you are too tired or too tight to hang your clothes on hangers and put them into the closet.
The feet thingies..come in real handy for plants. Put plants on and raise and lower to accomodate the sun requirements of said plant. Helps if you live in summy climate.
It can also be used as guest seating in the event of a great football playoff. I believe there are handy cup holders for the refreshing beverage.
