Art, which appears to be centered on the wall. Position table/chairs centered on the art. No rug. Now, add two chairs on either end of the table. Without measurements of the space, you may have seating for six.

Not a pro, but i think rug, table, and chairs work well together with a clean MCM/Scandi vibe. Can the table be centered better on width of rug? Is there an off-centered light fixture that is throwing things off? If not, center rug, table and artwork on that. Agree that you probably have room for 6 chairs, if desired. Nice job!

I like them all together and agree about centering on the rug, if possible, but it's fine, as is. The chairs against the wall may not stay on the rug when someone sits in them.

I like the uncrowded look of 4 chairs and wouldn't add more if you don't always use them. The rounded ends of the table are so pretty without a chair hiding them. Great find on the table and chairs!
