Serpentine tables are curved 1/4 circles.  When you put 4 of them together (going the same direction) you create a circle with an empty space in the middle – the perfect tables to go around a support column or tent center-pole.  Place them together and add a 60" round table to the center to create a round table that can seat 16 guests.  A curved bar or an interesting buffet display.  The possibilities are endless.
