Experience with Risedesk Ergo Chair Pro

I'm hoping somebody has actual experience with this chair that they can share.

I've seen opinions that suggest the Risedesk Ergo Chair Pro is perhaps nothing more than an expensive Chinese-made chair of questionable quality but I've not read any comments from anybody that owns the chair and has actual experience with it (other than reviews on Risedesk's website).

I do see that they are a fairly young company and that might explain why the shortage of real world user reviews. I also see that they have a fairly short warranty of 3 years, which is concerning. On the plus side they do offer a 30 day trial but that doesn't really help with getting a handle on the longevity and quality of the chair.

I don't have the money to spend on a new high end chair and was leaning towards a re-manufactured Leap V2 from BTOD or Crandall (12 year warranty) when I found the Ergo Chair Pro. I'm not able to actually sit in the Leap V2 and have had it suggested that it might be a bit narrow at the rear of the seat arms for me. The Ergo Pro looks to have a lot of flexibility for fit.

I'm a pretty large guy (6'2" and 270lbs) and I've gone though a few chairs in the last 10 years and was hoping this might be the last chair I have to buy (I'm in my early 60s).
