We were able to assemble it in less than an hour but when we found out we missed a step in connecting the legs to the chair we were told by customer service that once you put the seat on the legs there was no way to remove it!  So what if I didn't like it once it was assembled?  There is no way to take it apart to send back as a return.  Luckily the chair works for my "home office" but I thought that it was crazy that you couldn't dismantle it.  I was also very disappointed that FedEx delivered it at 9:51 pm the day of delivery and the box was on our porch on a foggy overnight and was damp when I discovered it at 7:00 am. The box could have easily been stolen and FedEx never even rang the door bell. To me, end of day delivery is end of "work day" (5:00-6:00) not almost 10:00 at night.
