I have to say I am pretty impressed. I use this chair mainly to play guitar, read, and occasionally for gaming, and it works very well for my purposes. I am a pretty big guy, and I don't have any issues or discomfort while sitting on this chair for extended periods of time (this was my biggest concern pre-purchase). It's also lightweight, looks good, and arrives in the box with no assembly required.
The only small nitpick I have is with the mechanism that adjusts the angle of the back of the chair which is slightly wonky. It took me a moment or two to figure out how to adjust the angle and lock it in place. This chair is also quite low to the ground, so keep that in mind.
All in all a great purchase. Will update if I encounter any quality issues in the future.
