Gaming Chair Office Chair with Lumbar Support Footrest

My son is very happy with his new chair. So far it’s brilliant. Good value as well.

It's nice. It's comfy. But it also makes sounds. Like, there is a popping sound that I couldn't place for like two weeks and now I know that it's coming from the chair. I thought I was having auditory hallucinations but nope, it's just the chair making weird noises.
