Four chairs fit along each long side at 24 inches apiece, 8 seats, the same count at 30 inches each with a chair at each end. Plan on about 16 by 12 feet with 48 inches between the table edge and the walls, so chairs pull out and people can walk behind them.
Each O-leg is an open loop of steel, 24 inches wide across the table, so it stands about 12 inches in from each long edge of the top. The steel is 1 inch thick and 2 and 1/2 inches deep with a silver powder-coat finish, and a square steel spanning rod, about 1 inch across, ties the two legs together. The two legs are the only parts that stand on the floor, each on adjustable glides for leveling.
On this 8 foot conference table with open-frame legs, the legs are open steel and hide nothing, and this length has no wire box: the laminate wire box between the legs starts at 10 ft. Cords from a power grommet drop from the top to the floor.
Pick one to three power grommets on this page, set across or along the table, and they are cut into the top before it ships. Some grommet types also take a connection plate for network jacks, or for HDMI and VGA. Up to three matching credenzas can be picked here too and are built with the table.
