Usage: I had the chair for 8 months. However, I have been actively sitting on it daily and working for about 2 months. 

Pros: Beautiful Chair. Quality Upper Material. 

Cons: 
1. We followed the instruction and built the chair. Early on it was fine, but then the chair started to squeak and we realized that it's also becoming a little unstable. We tightened it up a bit, but then the same problems started again. 

2. The seat sank within one month of active usage. So if you are working on this chair 8 hrs a day, I do not recommend buying this. But if this is just a casual home office chair, where you only sit 30 mins max a day, sure maybe.
