Adjustable Bench

I don't like going to the dentist and really, does anybody? But you have to admit that dentist's chairs are pretty cool when it comes to "adjust"-ability. In this example, this heavy work bench is made out of a piece of laminated beam with a shelf underneath. The whole thing is bolted to a dentist's chair mechanism. It swivels and goes up and down. There is also a brake that locks it in place as you swivel it.

Of course barber's chairs work remarkably well as bench bases, too. Luthier Michael Sanden from Sweden made this one from a barber chair he had in his own barber shop. It too, swivels and the lever pumps it up and down.

You can find these old chair mechanisms online for a few hundred bucks but the proliferation of tattoo parlors has driven the price up. You still find them at flea markets and even in old barber shops. But it's a neat way of getting the ultimate adjustable stand for the ultimate adjustable workholding tool - Grip-All Jaws.
