Of course, no floor you set it on is going to be the same, so get the
glides
with some rubber equalizers in 'em.

Or use the shaker method; drill the ends of each leg and insert a hardwood
dowel. I prefer about 3/4"dia. but it depends on the leg size. Trim the
dowel so it protrudes only about 1/4" and use loutent's stand'n'sand method
to get it sitting level.

This also has the advantage that once the dowels begin to wear excessively
you can simply replacve 'em rather than having to do major surgery to the
leg.
