Pictures would be helpful. Why couldn't they order the matching chairs when you purchased?

I like the black with the table. You can use them on the ends or can you exchange the brown ones for 4 more black. I don't think it's a fad when it works with your style.

Thanks, tried them on the ends and were not crazy about how it looks. The brown chairs were on final sale when we ordered and apparently only had 4 left thats why we had to get 2 black, but now it looks like either someone cancelled an order or they somehow found more of them because I can order them, just unsure and delivery charges from PB are expensive and non-refundable. Would have to sell the 4 browns second hand.

No, not a fad. I’ve had black chairs with a wood table for over 20 years.

According to google:

Yes, it is perfectly okay to have mismatched dining chairs . Use different chairs at the heads of the table than the ones on the sides. This is a common and effective strategy.

couple more pics

i almost feel like its too much black with the coffee table, stools and black chairs

This is a Pottery Barn photo—-similar to your set, with upholstered chairs.

Why do you have a TV in your dining room? Forget black or brown chairs— that’s the real issue.

Its not a formal dining room its the kitchen table

I kind of like the black at the ends with the brown along the sides. It gives a little relief from all the brown everywhere and looks very intentional, and since you do have that large black screen, it brings some more black into the space.
