I bought the desk, technology table, and book case.  The desk took the least amount of time to assemble.  The directions are well written and have great coordinating illustrations.  Each piece took about 1.5-2 hours to assemble, and I was working alone (female on the smaller side).  I strongly suggest waiting to tighten the "hidden cams" until the end.  Simply, just follow the instructions.  Great quality especially for the price.
