Best praise vs top criticism for Humanscale Trea
“[Humanscale](https://sonicratings.com/most-comfortable-chairs-by-humanscale/) makes pretty damn good ergonomic and comfy chairs, I'm enjoying one right now as I'm sitting down and writing this :)) Comes from a guy with serious back issues and I'm sure some of you can relate to that issue. But, there's a comfortable solution here.”
“While I'm a Leap V1 stan, I'm disappointed to not see anything from Knoll, Poppin, Teknion or Humanscale on here. Seems like there's at least gotta be some Contessa fans in the sub.”
