tldr; Mesh alternative to Aeron with forward tilt. PostureFit lumbar is polarizing. Good for active sitting and hot environments.

Best praise vs top criticism for Branch Ergonomic Chair
Best Praise
+3 pts“I used a branch ergo at work was really good better than the autonomous. Not sure that helps.”
r/OfficeChairs
ViewTop Criticism
+3 pts“They don't publish all of the negative reviews they get on their website. I'm also convinced that a lot of professional reviews are based on short-term use, not extended trials. I would strongly recommend any random $150 office chair over the Branch Ergonomic chair-- this is coming from someone who has had it 2 years, and who has also had shitty rando chairs that are more ergonomic.”
