computer chair

Hey all, i'm hoping someone can help me... So my old PC chair has had it. I'm looking for a replacement Work/PC/Gaming chair. My budget is about £150, but can probably be flexible with price if it's the right chair. Really, as it's going to be used as a work/ Gaming chair i need a few things...

Can anyone identify what chair this is from this video of my man Colion Noir? I think it's a popular (and expensive, fk) one but I'm not sure which one. Winner gets to feel good about themselves!
