Love this chair but I needed to have a handyman add additional screw sets in the back to reinforce it before I could use it.  It came with ONLY ONE screw  nut to hold the chair together (leaving a very wide gap between the sections which connected in the back of the chair) and it was a real safety hazard.  If someone were to sit in it and the ONE came unscrewed that person would end up (possibly injured) on my very hard tile floor.
