It works as a chair without falling apart. It's not even uncomfortable, at that, and I sit on it for long periods of time. However, what the chair claims about "tilting/rocking 25 degrees" is a complete lie. It rocks minutely, maybe a degree or two, not because the back is built to do so, but because the connecting rod is just a tad bit too flimsy and ever-so barely shifts or "rocks" in all directions like a ball-and-socket depending on where you put your weight. The adjustable lumbar support is a joke, too. If you try to raise it any and then put your weight back, it lowers back to the minimum. Thankfully the minimum happens to mostly work just fine for me.
