Attractive but doesn't sit level on floor

I like the look of these tables + they're fairly well made. They could have been packed more carefully; there were a few tiny chips in the wood on arrival.The one thing that bugs me is they don't sit level on the floor- if you press on one end you can tell the other is slightly off-balance. Rather than hassle with sending them back, I am going to enlist the help of a friend to see if there's a way to make them level on the bottom.
