This is far most the best chair I have ever bought. I used to use the back joy for my back with my chair for my office. Now i do not need it this chair is great for the back. I sit in this chair over 8 hours a day and i have no back pain. Love this chair!!!! good price for this chair i highly recommend it!!!
The chair is great!! It's by far the most comfortable office chair I've ever had. It has so many adjustment points that it can really be tailored to your preferences. For reference I am 5'9" 180lbs and everything hits in just the right spots. I would definitely recommend this chair for average height and build people. One note I could offer is adhering to the weight capacity of 250lbs not that I think it couldn't hold more but the material would sink and likely create extreme pressure points since it essentially suspends you like a hammock.
It is the perfect chair for ankle knee and back pain. I can sit very comfortable for a long period of time. Love the adjustable seat. The mesh keeps me cool.
