I have had this Mid-Back Black Mesh chair for a few weeks now.  The chair came in a box and had to be put together, I was able to put it together easily by myself without any issues.  The cushion on the bottom seat is fairly comfortable to sit in, and the back comes up enough to offer support. The chair can be easily adjusted to go up or down, so it is small enough for my 7 yr old to sit in and tall enough for me, while still easily fitting under my desk.
