Replaced my "gamer chair" with this and not only is it more comfortable and much better at posture support but my shoulder pains have actually started to get better since I ditched my old chair for this. It took me about 20 minutes to set up. Only downside is that its not as customizable as some office chairs but it just happens to have setting that suit me perfectly. Aesthetically it's quite nice looking. I got the blue one.
The chair is what I was hoping for but there are a few issues I think you should know about. When you lean back the lumbar support snaps down so for long sessions you're better off keeping it in its lowest position as it will eventually fall back to that level when you lean back anyways. The chair also tends to rock side to side a bit in a way that does not feel natural. Very comfortable otherwise but I would like to see these issues fixed. For reference I'm a 5'11" male 175 pounds with a 32 inch waist.
The chair was simple enough to put together. All the parts fit together nicely with the provided tools. I like how it reclines and feels when I am sitting in it. Its nice and breathable so I feel cool even when in the chair for hours. The wheels roll nicely with out much effort. There is plenty of elevation adjustment so thats no issue even for someone small like myself.
I have been using this chair for around 2 weeks and I think it is good if you are used to mesh chairs. My thighs and ass needed to adjust to the mesh but overall it is good. It gets hot over here and having the mesh chair definitely cooled my ass down. I think you need to be decently tall to use the head rest. I am 6'1'' and it seems good for my neck but if I was shorter it would not position well. I wish I could lower the arm rests some more so I can put my chair underneath my desk when I am not using it. Overall it is a good purchase.
