A butterfly leaf table is an expandable dining table that expands with a self-storing leaf. This popular expansion design typically has a leaf (for leg tables), or two leaves (for trestle and pedestal tables) in the center. A butterfly leaf is named because when it is being "opened' into place, it appears to have wings like a butterfly. A butterfly leaf table can take almost any overall shape, but the most common are rectangular or circular. Our solid wood butterfly leaf is normally around 18 inches wide, and hinges in the middle. You can simply pull the ends of the table top out, revealing a gap in the center where the leaf is stored.
