If you have long dinners, they are not particularly comfortable. I gave away a set years ago. Ok for quick meals.

Wishbone style chairs look nice with that style table. http://allissiasatticdesign.com.au/products/rodin-cross-leg-dining-table These resin chairs are stackable. Lots of different designs out there in resin chairs. http://www.zizo.com.au/Capri-Arm-Chair-WARW1025.html http://www.zizo.com.au/Ibiza-Arm-Chair-WARW1026.html

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.

Nice chairs. Have you browsed the Temple and Webster site. Lots of dining chairs. I'm a magazine tragic but I don't recall these chairs having a distinctive name. They look slightly like Eames copies but not exactly.
