Affordable ergonomic chairs that arent HM or Steelcase?

Hi all, anyone have recommendations for decent chairs that arent these brands?

Used chair resellers in Canada sell these at affordable prices but they're usually 10+ years old. I bought a leap v1 like this previously and I've had nothing but problems with it, so not going down that path again.

Are there any other brands someone can recommend worth looking at? Most chairs staples sells have very limited adjustability in one part or another.
