Got my chair just before Christmas, so I haven't use it but one time so far.  It was easy to put together... took me about 20 minutes - only because I'm not as strong as a man and it took a little bit more effort to get them attached... the rest of the chair was easy enough... did have to clean out a couple of the screw holes so that the screws would go in, but everything lined up and went together just fine.  I have used it once since putting it together - and it sure beats what I had before!  A world of difference.
