King Louis chairs can vary ....

We need a picture of the chairs, table, and dining space to make an educated guess at what you should buy...

You won't be able to push them under the table at the ends. Do you often seat 8?

We do occasionally have 8. ideas?

I’d do a slipcovered Parsons style. Something not too matchy. This doesn’t have arms, but maybe you could find something similar.

ETA: Pottery Barn has them with arms and lots of fabric selections:

A Louis XIV or Regency armchair!!!

People will have trouble pulling close enough to the table to have realistic fork to mouth space with chairs like Albert posted. They're beautiful for another room though.

Depends on table height and if you add lumbar pillows.

Door grids, lovely bricks, view -- so I like jinx's fabric cover that softens the room. Maybe a pretty but subtle pattern could complement.

Some places offer just the covers, and could be changed again and again.

I wouldn't use this location for fancy end chairs, not with basic table... I bet an accent chair could go somewhere...

Since the other chairs take up most of the visual space of the table, I'd opt for something with a lower profile that coordinates more with the rustic table and floor, yet is rounded to "go" with the other chairs.

IMO no head chairs you already have a very specific mix of style here and IMO adding another would be ahuge mistake not to mention head chairs are dated anyway and since the table is far from formal just do 2 more chairs the same.

It’s not dated.
