Bring on the pattern! Especially if your sofas are a solid, then introducing a pattern on the chairs would be a great way to add some extra visual appeal to your space. I would stick with a fabric that only incorporates a couple of colors. Then, you can use pillows to add extra dashes of bolder colors or funkier prints.

What couches are these? I like the exact style. Do you know the company?

I most normally would favor a solid color fabric for dueling sofas and adding patterned fabrics for pillows.
