Mix and match your dining room chairs
Mixing different styles, as long as they are similar in height and colour can add individuality to your dining space.
Make sure you leave over a metre for chair pull-back space around your dining table.
Dining area sharing a space?
If your dining area is sharing space with an open-plan kitchen, consider "separating the spaces" with area rugs or a decoartive dividing screen. Lighting can also work well in this situation: use brighter task lighting in the kitchen, and softer ambient lighting in the dining area.
