Do all 10 chairs need to be at table all the time or can it be 8 chairs and 2 you bring over from somewhere else for large sit downs? DIAL UP YOUR CHAIR sizes to be proportional to table so, as to not look like child size chairs. Restoration Hardware furniture is over sized and generous proportions compared to many other retail sellers. Just any chair could be easily dwarfed by the RH table and look tiny. Here are a couple of my favorite modern chair makers KNOLL Brno flat bar chair which can be bought at auction and recovered in leather or vinyl of your choice and David Edward Furniture made for corporate, resort and colleges and available through dealers, I am showing here as a "host chair". Other "host" chair items possible of course. I just like this one.

Hi anzella, loving the new table and chairs, because you live in North QLD I wouldn't worry about a rug under the table, apart from you climate I find rugs under tables can become very annoying . If however you do decide to have one down the track, Sisal Rugs are great for your climate, you can even make your own to whatever size by buying the sisal and edging it yourself or getting a carpet place to overlock the edges. Some years ago I made two very large rugs and edged them with a wide black tape, I stitched them by hand, loved them in the dining and joining living room.What a shame you can't have the hanging lamp in the picture over your table, not sure if it would fit between your ceiling fans. cheers https://www.dealsdirect.com.au/product.aspx?saleID=1774c795-993e-4615-afbc-f53a2e1dcab3&productID=ojiuDsjunkG1Vz9n7zBrLQ&sc=7&c=12&mkwid=siJYklREw_dc&pcrid=189771976719&pkw=&pmt=&product=ojiuDsjunkG1Vz9n7zBrLQ_6xX6Gc4vLkKMpQtba7S3jw&gclid=CjwKEAjwoLfHBRD_jLW93remyAQSJABIygGp4cKCQmlURqkE4IbUxZFOwwVQKSQHTM9Fx7Xllv1FvRoCWqrw_wcB
