Let me start by talking about the packaging, this chair was nicely packed and secured, and it was delivered to me with zero damage. The installation was pretty simple, as well. It had a detailed instruction manual, and it has clear instructions on how to fix this chair. 

It is quite comfortable, and I really like how smooth the rotation is, The wheels can rotate 360* and I can say it is quite comfortable to sit and very smooth to move around.

I would rate this product 5* for its build quality, packaging, and comfort, and I highly recommend this product to anyone who is looking for a comfortable chair at an affordable price.
