I bought this chair just a little over 4 months ago for my home office. It looks decent and that's about the only positive thing. 
This chair is cheaply made. Within a month the arm rests started to get very wobbly and I had to tighten all the screws. I thought oh maybe I didn't screw them in tightly enough when I initially assembled it but it keeps happening so it must be how the chair is constructed.
Now over the last few days, I kept hearing a strange metal sound when I moved around in the chair and I noticed that a screw had fallen out of the metal attachment between the legs and the seat. I've tried putting the screw back in but it is impossible to reinsert it so not sure if I'm gonna be able to keep using this chair.
I'm disappointed. It's not an expensive chair but I've had $30 chairs from other companies that lasted longer than this.
