Oh man I thought the chair we never reached ;-) After beaten 6 or 8 weeks finally came our new office chair. He was easily assembled in a few minutes, the appearance is awesome that material almost very well at & we hope that it remains so, sitting feeling perfectly what my son is something interferes with that is something difficult to tilt function - me does not interfere with it, however, height is easily adjustable. So I can not find anything negative, except that just the delivery had lasted forever.
