Les, you would want very large wheels to roll over carpet. The best bet would be to weld up or have welded a drop center frame with the wheels mounted outboard of the base of that stool. That way the stool can sit a couple of inches off the floor to keep it from being too tall for you to manuver under the benchwork, but some 5 or even 7 inch wheels should roll very easily over even shag carpet.
