I give real ratings. 3 being "Okay" 5 being "The best ever".
My daughter wanted it, as I got a different cheap one from Amazon. Similar design, but different in a few key ways. A couple of little issues. The wood bar creaked and bent a bit when I sat in it. I am well enough under the 300lbs. And it is smaller than mine as far as how much of your body can be supported. Mine is mesh, and I can stretch my whole body out and kinda lounge fully supported. I also don't like the hanging bracket for it. Mine can rotate fully, hers wants to, but gets twisted. :-(
So, your chair is not bad. It just isn't great either.
