Assembly took about two minutes and it seems durable.  Unfortunately the foam is extremely stiff.  I think with time it will be broken in and help this problem.  Something I don't expect to get better is that, when leaning back, I can feel the crest rail under the foam on the backrest.  I sit like a mutilated shrimp so this is rarely a position I'll be in, but it still seems like a design flaw.  

I would buy this again, but not enthusiastically.
