I work 50 hours a week from home and needed a comfortable chair since I also lean forward too much. This one was very easy to put together. I am 29 years old and did it in about 10 minutes by myself. I love mesh chairs because they breathe easy. Works well, tilts back, and the arms moving up and down are great. My french bulldogs love to sleep on my lap while I work so it's nice to be able to lift the arm up if I need to. Glad I purchased!  

Pros: Comfortable, easy to set up, flexible arms
Cons: none yet!!
