Chairs are very nice and I really like your table!

You've got to give more info than that. Do you have a picture of the accent chairs that you want to use as a dining chair? Also pics of the dining room and table.

I like the new chairs you are considering with your others I would not do kilim or juts in that space with those cahirs but maybe look for a great deal on a traditional persian rug and a round coffee table . IMO go for that old library look and I would for sure do drapes not blinds and remove what looks like a fake plant too. You will need to add some lighting for sure if there are no pot lights and just try for the ambiance of a library you are almost there .
