When choosing dining chairs stay with a consistent theme or color palette. Embrace eclectic looks by mixing different chair styles with a unifying element.You can use matching chairs at the ends and mix styles for side chairs, but ensure a common element, like material or color, for cohesion. Pay attention to size and scale for a balanced arrangement. Experiment with different chair colors and textures for visual interest. Lastly, distribute styles evenly for a harmonious look.
