Noble Chairs [Epic] - Good for posture?

[Dominic-Toretto]

Hey all,

I am in the market for a new chair, I am looking for an ergonomic chair that promotes good posture, while also looking good and being of high quality.

I have seen people recommending Herman Miller chairs, but they do not look comfortable at all, and look to provide no upper back support, or even lumbar?

Could any owners please chime on the Epic chair? Am I barking up the right tree with this chair with my requirements?

Edit: I also see people recommending the Ikea Marcus, is this a valid alternative?

Thanks
