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.

Anything with colour would be a bonus in your place IMO . So grab 4 cushions in the same blue , and 4 with say lighter blue and white stripes or chevrons ( wiggly things haha ) -- that references the dining chairs and brings in a lighter blue . The cushions are for the couch btw , in case you hadn't clicked haha . Maybe a rug . Definitely a larger artwork with the dark and lighter and maybe a mid blue too , a splash of yellow and orange and grey in places . Suddenly , its gone from drab to okay . One thing I do slightly worry about though is the table top colour -- its got olive green drab tones to the brown IMO , and will probably make both the top , and the chairs , look plain and almost muddy in vibe -- a Japanese Black stain on the table top ( similar to your island front ) would look better with blue chairs in my mind .

That should be Kave. Autocorrect! Also have a look at Temple and Webster. A good search term is “carver fabric dining chairs”

Have a look at Brosa Zoe they have a 200kg capacity , they are lovely and they are on sale
