Both approaches work beautifully, depending on your style and how formal you want the space to feel. Matching dining chairs create a cohesive, traditional look that suits formal dining rooms. Mixing chairs adds personality and relaxed charm, particularly when combining different styles around the same table. For a balanced mix, keep one unifying element.
Match wood tones across modern dining chairs and traditional styles, or choose contemporary dining chairs in complementary colours. Pairing dining room chairs with a bench creates visual interest whilst maintaining harmony. Confident coordination matters more than exact uniformity.
