I like the chair -- roomy and comfortable.  I thought it was pretty easy to put together until it was time to deal with the bolt that goes on the top of the C-frame.  There are two bolts -- one is obviously shorter than the other.  The long bolt goes through the top of the C-frame, and where it comes out on the bottom, you're supposed to slide on two chains and a washer.  But it completely covers up the hole at the bottom, which made it impossible to insert the spring (which is what the chair hangs on).  Tried a million different combinations and ways to deal with this.  Called the manufacturer and another bolt was sent.  Exact same size and problem.  I eventually gave up and had my husband make the hole larger/lower.  Hopefully this won't compromise the safety.
