I have a Lazy Susan in the middle of my table and this is a sturdy napkin holder.  I just stuck some little felt tabs on the bottom so it wouldn't scratch the wood.  The best thing about this is it actually has 4 sides.  Other than the ones with paper weights on them, this is the only kind I have seen that has 4 sides, and it is upright.  We saw it at my mother-in-laws and bought one online the same day.
