This chair has made some improvements over the previous versions such as better seat padding and the adjustable back. The things I liked about this style chair are the mesh back and multiple seat positions. The new thing that comes with no instructions is the height adjustment for the mesh back with lumbar support. At first one might think that the lumbar support moves in and our as with many vehicles but the knob only locks the height settings. After some coffee and an epiphany moment I tinkered with the knob on the back while sliding the whole matter up and discover that there are three locking points for the back plus a fourth position at the bottom (unlocked).
The seat on the chair is extremely comfortable and I like that there's a lot of flexibility in the adjustments. The arms don't work very well; I like having arms but they don't really clear the height of my desk so it's a bit inconvenient. I may need to remove the arms entirely. Otherwise a great chair at a good price (if you can catch the sale).
This chair is quite comfortable and the price can't be beat. It has lumbar support and enough seat padding. Plus it was delivered rather quickly in three days.
This chair has multiple adjustment capabilities. I really liked that because I can directly adjust the chair and its angle to fit my lower back pain. The foam seat is softer and better for me than the mesh seats and also relieves some of the discomfort I felt sitting on harder chairs. This is a great chair.
