My problem is I have a nice pedestal chair I don't want to get rid of, but I would much prefer the mobility of being able to move it without getting up. So, is there any (safe) way i could put some sort of attachment or mod on my chair?
A photo would be very helpful as there are several styles of pedestal chairs.
As long as the chair is a comfortable height, you can put casters on any chair and make it mobile. Go to your furniture store or a large dept. store or online to see what size you make need.
