Anderson Teak Bahama Wilshire 7-Piece Oval Extension Dining SetOval Extension Dining Set Seating Six on the Patio An oval extension table softens the lines of a six seat dining set and seats two armchairs at the ends with four side chairs along the curves. The leaf opens for guests and closes for daily meals. The oval shape eases traffic around a patio better than a hard rectangle, and the rounded ends give the two armchair seats a touch more room.
