I bought this one from Flash Furniture via Amazon. I've had it for a little over a year now.
The arm rests are a little too wide for me, clearly intended for someone who weighs a lot and is a lot more rotund than I am.
Regrettably, the cylinder started sinking about a year after I got it. The chair would just randomly drop. By sheer coincidence, the replacement part arrived today as the chair thankfully has a 2-year warranty on that part.
I've been using this chair for the past several months - https://www.amazon.com/gp/product/B00SNZ59DC/ref=oh_aui_search_asin_title?ie=UTF8&psc=1
It's a good price at $182 and real sturdy. Only downside is that one of the wheels, on mine at least, seems a little stuck.
