You are probably very familiar with all the furnishings mentioned, but personally for me it’s extremely hard to imagine all the things you mention, let alone make any useful suggestion. I noticed you also posted about living room. You might want to put those two posts together, include more information (is that your actual dining room?) houzzers are indeed terrific, but sometimes there isn’t enough information or context to even guess. Your possibilities look quite expensive. Good luck!

You don't need to match colors, but select a softer version of the color of your sofa. My idea of pulling everything together is to use the same colors throughout the home to create harmony and tie everything together. Starting there, you would use a shade of the blue on your sofa for your dining room chairs or accessories. You can also add two accent colors that work with your sofa and bring those into your dining room plan. Hope this gives you a little bit of a plan to proceed. Love that sofa!

Is this your actual sofa and chairs? Do you have any photos of the actual dining room and color options for the table? The table is a very unusual style (to me) so I have a hard time visualizing it In a room, or what kind of chairs or color would possibly work with it.

Yes. The pieces are interesting.
