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.

OK... final grasp at a straw - your set of chairs for when they are not visiting, and when extended family come over, bring out fold out chairs with washable slipcovers? I know how difficult it is when you want to have a room that you like but you are having to adapt it for just for the one-off occasions and not as you would like it ideally. Perhaps that might work so you get what you want (most of the time!)

What a beautiful room, table is great, I love transparent furniture also it could work well with your room, I can imagine it with your table but a more luxe look could be stainless to blend with benchtops or leather or be brave and mix it up for a more contemporary look, depends on the style you are after, fab room

A dining room rug should ideally have 24" or more of extra space, surrounding the table. The guests should be able to pull out the chairs easily without tripping over the rug. Choose flat weave or low pile rugs because spills are inevitable from the dining table. Maintenance and cleaning become simple with flat carpets. You can also choose carpet tiles as they can be set up according to the shape and size you need. Rugs come in many colors, patterns, and textures. Feel the texture if you are purchasing a natural fiber rug because natural fiber rugs are hard and rough as compared to cotton. Match the shape of the rug with that of the room. Match the rug shape to the room shape and the table shape.
