Fiction: For a sense of cohesiveness, your dining room chairs must match each other and the table they are paired with.
Fact: Dining room chairs don't need to be matchy, matchy. In fact, choosing a variety of chairs lends itself to a more personable and inviting space. You can do this by introducing a bench alongside a set of chairs or adding a unique pair of chairs to the ends of the table. Do try to keep a consistent element among chairs like shape, hue, or finish.
