Mixing dining chair styles intentionally works best when the chairs share at least one common feature, such as colour, material, height, shape, or finish. Different chairs can look stylish if they feel connected, but they can look messy when every element clashes. Keep seat heights similar so the table remains comfortable and balanced. A safe approach is to use matching side chairs with different end chairs, or mix chair shapes while keeping one colour palette. When the design has a clear pattern, mixed dining chairs feel curated instead of accidental.
