I ordered a Herman Miller chair and it came pretty quick and as ordered. I noticed a few issues like the left arm doesn't stay up after locking into place and the back leaning ability seems 'off'. The chair also does not have any serial tag or Identification that it is a Herman Miller chair. I have reach out to Seating Mind for warranty information only to be asked over and over for a video of the broken chair. The shortest I can make the video to show the broken components is 55MB which I cannot send via email. Needles to say I am stuck with a 'so called Herman Miller' chair that is supposed to have a 12 year warranty and I cannot get any information or serial number for the chair to contact Herman Miller. My advice is avoid purchasing from Seating Mind if you are looking for a high end chair like Herman Miller.
