First IMO head chairs are a formal and dated look and that table for sure is not either of those.You might want to look a t butterescotch colored leather for the choirs if you are going that route for the LR since that kind of makes them work togther. then add some pale teal as an accent . I would also suggest to add a thin piece of glass on that table top since concrete stains really easily.

What chairs was the table shown with? You may need a specific size depending on how they are arranged (2 on each side or 3 on opposite sides with one at the head and foot). If you have any old dining chairs or folding chairs, try arranging them to see what width chair will fit comfortably.

Congratulations! Your home is beautiful, I really like what you’ve done so far.

There are so many ways you could go. One idea is to mix casual, traditional, and textured with chairs a touch more sleek, luxe, and modern. I like the gold legs on the side chairs for the connection with your great fixture.

Not necessarily these exact chairs, but just to show what I mean:

A simpler idea would be to do all Parsons chairs, slip-covered or not. They’re a classic with so many styles, and comfortable. Slip-covered ones would bring a nice softness to the concrete table.

Ballard’s has some lovely ones in various colors:

I would do black chairs, but nothing too bulky

@Patricia Colwell Consulting Thank you for the advice. We hadn't looked at leather dining chairs yet. Also, we plan to get a large piece of glass cut to cover the top of the table to prevent stains!

@apple_pie_order The chairs they had with the table were rattan+woven chairs that were very a very coastal beach house style. The dimensions of the table 95"x40". Attached are photos of the table with one of the chairs from our patio furniture and one of our high-top chairs as suggested for sizing purposes. The black chair is 25.5" wide at its widest point and the grey is 20" wide at its widest point. Ideally, I'd like three chairs on each side and one at the head and foot.

Now seeing the black chair and other chair, I think the other chair actually looks good with it ...color wise.

Here they are:

And if you do a search for ‘cream dining chairs gold legs’ or similar, lots more styles come up. :)

ETA: Wanted to say ... these MCM types of chairs like I posted for you are comfortable and I love how lightweight they are, but still sturdy. I got four of the one below for my rustic Amish-made table, leaving the two heavier, wood end chairs. Love the mix of styles.

I've been shopping for dining chairs and really love cane-back chairs and ones with rush seats (you mentioned texture).

I've been fascinated by cane-back chairs lately (that I can't have because of my cats), and you mentioned texture. The one on the right is vintage and very expensive, but I'm including them because I love them and your budget may be more generous than mine.

I agree with Patricia that you need an accent color. Your bedroom is perfect - It feels right. The second room with the white carpet feels devoid of color, like I am drowning in a sea of neutral.

The living room has the brown leather chairs, which add warmth, but my eye is still searching for color.

For chairs I think classic MCM teak chairs would look great. Add warmth with wood.

Would do an upholstery that pulls the "color" you choose as an accent from the living room.

Something like this color - a subdued grayish green.
