I used to accomodate my bad back and short height with three different pillows on my previous chair--no more! This chair fits me perfectly. And it's so pretty; I got a compliment as I was leaving the store with it.
I have a small office space in my bedroom and Hyken Mesh chair fits nicely much better than the chair it replaced. It is also more comfortable and ergonomic leading to less back pain that seemed to follow long stints with that prior chair. I weigh about 150 lbs and recommend this to anyone who needs better support though I cannot say how it will be for anyone who might be somewhat heavier.
I've been a fan of mesh chairs for a while. I can't afford $800 for that one brand so this is a good alternative. The wheels are the one part that really feels like a discount chair. I swapped them out with some 3" roller wheels and feel like I have a chair that punches high above its weight.
