In French homes there is always a combination of seating in the living room. A comfortable sofa accompanied by several more formal chairs, often antique, often mismatched. The room is pulled together by the colour scheme and the fabrics.
In the bedroom, there is often a single chair placed beside a window, or a small upholstered bench at the end of the bed. I love to see a comfy armchair in the bedroom too.
Around the dining table or in the kitchen, seating is generally wooden chairs with loose or upholstered cushions - they have to be comfortable with so many hours spent enjoying good meals!
