Hi

We love mixing and matching, especially when it comes to a dining room set. By not just going out and buying a dining set you will be able to really cultivate your space and curate the items in it. We agree that the bench is probably the most functional solution for the space and would reccomend placing it on the side with the painting as to not cover up the beautiful art you have chosen. Our suggestion on mixing material is make sure that it looks intentional. If you choose different materials (i.e. the color wood on the table versus the color of the wood on the bench legs) that are only slightly off it may look as though you tried to match but you were not quite able to find the exact color. We hope this helps. Happy Decorating!

You need a trestle table base. A bench with a four legged table is super awkward. Think about getting in and out. I have forgotten a lot about your previous thread, but I'm confident this is not the best solution.

Sorry but in your "tiny area" situation I would not suggest the bench. I think it would be super awkward in a tiny space to get in-and-out of where as a chair would be a bit easier. If you want to mix-and-match try not to over do it in a tiny space....I would suggest to keep the area simple and clean lines, with all of the chairs matching.

Is this dining space going to be used on a daily basis or only occasionally? Since it is tiny, avoid fully upholstered pieces.

While I like the look of a dining bench, sitting on one for any length of time is not appealing.

It looks too big. In the other thread wasn't it determined you were constrained to about a 32x60" table to not be too big for the space.
