Check out Selma Dining Chair by Agrippa.

Agreed with Barbara! I don't like any of them.

The last option picture didn’t go through. We’ve looked for months.

I know the table looks mid century modern but the house and space is modern. This table will be the most MCM piece in the house.

That last one loaded in the OP. I like the chair the designer mentioned above.

I think there are better options than these 3.

I love that Selma chair too but can’t find a price. I’ll send an inquiry but my budget is $300/chair and I’m guessing that one is at least double.

They all seem wrong with that table.

This is the dining space as viewed from behind a kitchen counter so you can’t see the concrete floor. It’s still under construction.

I can’t get a response from the vendors for the price of the Salma chair. This is as close as I found of similar chairs closer to my budget. Would these be a better option? Should I start a new poll with different chairs?

Another stock picture of the table

In the stock picture, the chairs have upholstered seats. I think, for comfort reasons, you need some cushioning. The table is truly stunning. Keep looking till you get it right. But remember, people need to be comfortable for a long time when they come for dinner - especially holidays.
