Where to source odd sized banquette seating?

I seem to be finding either the wrong size or custom options that are not geared toward residential. Client has a very oddly proportioned breakfast nook

each side is a different size. She wants more of this vibe https://pin.it/29Pittr8X - any recommendations for where to source?

I would find a set of chairs you like and then try and find a love seat that matches and fits against the wall. There’s also the option of working with a local contractor or Carpenter to create something custom. Just depends on how much the client wants to spend.

Yes, I was thinking of trying to find something like an armless sofa with a slight curve but the measurements are so odd. She was thinking about a custom vanity and then decided against it, but she does have a neighbor who could build it for her.
