Three types of seating at one table, especially when there is a patterned rug and molding details is much too busy imo. The bench seating also doesn't allow you to pull it out to sit and push it in be the right distance from the table, so someone is scooting in awkwardly. I think you can use upholstered chairs on the ends, if you have room for it, and different ones on the sides. But from the photo it looks like you don't have room for chairs on either end. The legs of the chairs need to stay on the rug when they are pulled out to sit down. In that case, just use four chairs on each side of the table, and leave the ends open.

Why are painting the legs black???????????

I will never again buy dining chairs without stretchers. They're the cross pieces between the legs. In my experience, dining chairs without stretchers get wobbly very fast. Your pictures are hard to see because they're so small. Better to post them individually on the post or in your idea books.
