Would be quite hard to find something like that here in Australia , have you tried at shotts ? Why don't you import them from America ? Cassie would deliver for you right to your door

I'd agree with adding darker colours to the mix... if reupholstering things is not in the budget just by adding chocolate, charcoal or navy blue to the chair and bedding will help. Add some rougher textures, chunky knits, pin stripes, vintage linen and right on trend velvet.... Adairs have a sale for another couple of days on their linen and other products https://www.adairs.com.au/search/?q=Vintage+washed+linen Accessories to consider are things made of dark marble, timbers, geometric shapes and gold... A bold feature wall could give some mood to the room again in the above colours.

Dark timber with pale upholstery is perfect for your French Provincial style. White, gold or pale timber can also work but the dark timber will give you the elegance and contrast you are looking for.

Are you combining a good way of sitting with a good design? If yes, arm rests are nice, when a dinner takes longer than 1 hr or so. It helps if there is a cushion available that people want to use where the back of the chair is rounded (and people prefer to sit upright). Under no circumstance should the seat slope backwards. The sitting level should be flat - no slope. The cushion can carry a lot of design and colour suitable to the environment. I love simple chairs .... and it helps not to put too many chairs around the table.... (unless you have a big family), have two chairs against the wall somewhere close. Sit on chairs before you buy them. (And a personal thing: I LOVE different chairs. Never more than a pair of 1 design) - like in the picture with the2 green armchairs and the bench. That is just great and suits different situations and guests. (To siriuskey...... I would sit on the bench)
