This is a EasyStand 2500 mobile stander. It allow you to stand and roll around the house or garage. I've had it for several years but am no longer able to use it. It's in good working order but some of the plastic on the rear casters is starting to crack and break off. Other that that it's in good working order. Asking $600 and buyer pays shipping.

I have pictures but was unable to load them on this link. If you're interested I can send them via email.
