Once you have decided on the range of chairs that have the perfect back as far as you are concerned then you need to look at the seat. The seat of a dining room chair is very important because it needs to be comfortable and that is because if you are having a dinner party you and your guests may be sitting on a dining room chair for several hour.
Defining a space: If you have an open area dining room that shares a space with a living room or kitchen area, an area rug will help you define the dining room without using walls. Choose a rug that uses colors from adjoining spaces but still defines the space. Therefore a mixture of neutrals from the surrounding rooms with a punch of an accent color to match the dining room chairs would be perfect.
