For comfort, a chair needs to have arms. In a dining room, choose a pair of chairs that work with your dining set and buffet and could be used at the "heads" of the table should you need to squeeze in a couple of more people by adding chairs to the sides of the table. As long as it works with your dining set, is painted the same color or a coordinating color, the height doesn't matter as much ... but I'd consider shorter wider seats (than the chair shown) with arms the better choice.
