Seven chairs fit along each long side at 24 inches apiece, 14 seats; at 30 inches each, with a chair at each end, it seats 12. Plan on about 22 by 12 1/2 feet with 48 inches between the table edge and the walls, so chairs pull out and people can walk behind them.
Under this 12-inch panel base conference table stand three hollow laminate bases with squared corners, each 30 inches wide across the table, so each one sits 12 inches in from each long edge and knees clear it. Our guide on how to choose a conference table base calls this style a rectangular pedestal base: the same width across the table as our 5-inch panel base, but 12 inches thick along it, so each base takes 7 inches more from the chairs beside it. Each base has a swing door on one side, with a pull included, so you reach the plugs without crawling under the table; the two wire troughs between the bases carry the cords from one end to the other.
Pick one or two power grommets on this page and they are cut into the top before it ships, and where one sits over a base panel, the factory notches that panel for the cord drop at no extra charge (over the wire opening in the top of a base, or between the bases). Cords drop from each grommet and run inside the base to the outlet. Side-panel colors, silver metallic side panels and up to three matching credenzas are picked on this page and built with the table.
