This was one of the best labeled and had the best instructions of any piece I've tried to assemble on my own.  There are a lot of parts to it, but it's easy to do (I'm 8 months pregnant and did the whole thing by myself).  I DID manage to mess up on thing because I didn't heed the warning to not use an electric drill, but the manufacturer's customer service was EXCELLENT and replaced the two pieces I broke with no questions asked.  I had the replacement parts within a couple of days and was able to complete the unit with no more problems.
