Perfectly serviceable chair.  Good size and I like the placement of the legs.  It was easy to assemble, just took minutes.  There is a little wobble in the ball bearing/rotation piece, but much less than a traditional middle "stalk" chair.  Also, the cushions are a bit thin and squish quickly so I use a pillow under me.  The back of the chair is far enough back to allow a moment's recline, but when I am typing I am not touching the back of the chair.
