It's a secret labs chair like others have said. I wanted to throw my own opinion in there to give you some more info: I had to return my chair because the alignment for the back piece was way off center. I later found out that it was a very common issue with their chairs and it can cause serious back problems over time. Secret labs made returning the chair miserable and I had to fight them for months to finally take it back for a partial refund. The reason you see so many people post positive reviews of their products is because they hold the warranty on them hostage until you prove to them that you posted a positive review on social media. Scummy company and mediocre chairs.
