Having mismatched chairs around the dining table is a great way to mix old and new, or incorporate different trends, such as contemporary and traditional. Mixing styles from a different era can create a dynamic and unique interior. Keep the look cohesive by mixing and matching it in pairs. With that in mind, you can easily break through fashion by changing the two chairs at each end of the dining table.
The result will be a serene and symmetrical look that is always pleasing to the eye and, at the same time, adds more interest than a complete matching outfit. For an elegant look, try placing a pair along one side of the dining table. Or place opposing chairs in every corner, providing all the advantages of a pair and the interest of an unexpected style arrangement. Excellent post María, I have a round PB table that I bought second-hand and I love it, and 6 solid handle chairs that go with the table but that are quite clumsy, it might be time to freshen up.
Oh, and don't even get me started with bar tables at counter height: the feeling of having your legs numb due to lack of circulation while dining at a high table isn't something you want to share with your guests.
