VERY easy to put together - anyone could do it.  We have used it for a couple weeks now and I believe this is a very durable chair and should last quite a while.  If you have a big bottom then it would be a snug fit.  My grandchildren destroyed my last chair but I think this one is going to last longer, it just feels good.  I gave it a 4 star rating only because if you sit in it for prolonged periods of time, it is not very comfortable.
