I'll give it a four rating based on how it feels once it is put together. The real test is after a year or more. We'll see. I'd give it a five rating if it had gone together with less hassle. The left bracket on the seat where the back is bolted to it: the "U" shaped bracket's holes do not line up. In order to push the bolt through I had to angle the back so that the bolt could be forced through at an angle; this made tightening the nut a bit of a slog but I managed. Everything else was easy and the hardware is very well organized on the shrink-wrapped cardboard; there's no reason why any hardware bits should go missing if you just go at it step by step.
