JONPONY Ergonomic Office Chair，Swivel Desk Chair with Lumbar Support, Adjustable Height with Armrests for Adults,White

I am giving this chair a workout. I have a 5-ft high walkable crawl space with a cement floor. I'm 5'8 and it's very difficult to walk around down there so I bought this chair and I'm using it to scoot around from place to place, as I work on revamping my storage areas. it is nice looking with a comfortable seat. I am finding it stable and it is serving its purpose. My complaints are these: this chair is rated for 300 lb. I am 200 lb and there is no way a 300 lb person would fit in this chair as I am finding it snug. Secondly, I know I will need new wheels since they will wear out rolling around on concrete; there is no place to order replacement parts. I've only been using it for 2 weeks, and it seems good so far except one day it was making some creaking noises so maybe something slipped out of position - I'll let you know if I end up in a heap on the basement floor. I did not want an expensive chair to start with because it was not sure how good of an idea this was for crawl space transportation. Bottom line - I like it, I just wish it was wider and I knew where I could get the exact wheels for this chair.

Not enough padding/cushioning on the seat, where I sit, it makes a creaking noise if I move in the chair like when I get up to stand or when I sit down. I read it was supposed to rock but I cant figure that out and I feel like I'm falling forward both sitting and laying back in the chair, I dont see a way to fix that. But the heat %26 massage are nice. Also can't find a customer service number to ask questions. Also there's a hole where the remote goes.
