That's an interesting dilemma. I would be inclined to go with the dark grey chairs because: - the chairs will be under the table surface most of the time, so it shouldn't be "too dark" when combined with the dark grey sofa; - the dark grey should tie in well with the sofa; and - the dark grey will provide a nicer contrast with the concrete table surface. Does the store you're purchasing from have a returns policy? If you explained your dilemma, they may allow you to take one of each colour home to see which colour works best in the space. Alternatively, can you go to the store which stocks the table, see what other chairs they have in the showroom and see if there are some light grey and dark grey variations that you can try in the store?

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 have not been able to find the designer of the chair 1stdibs can't help so I search all of there chairs and a couple of other 21st centry furniture places aren't sure I am awaiting to hear from Mary Featherstone to if it's one of there desgins

did granny also leave damask table cloths which would lighten the look instantly and, although i was very shocked at first, my sister in law PAINTED the antique chairs left to them and added some country style fabric seats and now uses the chairs with a modern table and it looks fabulous and is a daily reminder of dear old granny and i think she'd agree that you should mix and match what you like in your own home
