Someone was supposed to assemble this unit but never showed up.  I decided to do it myself.  Except for help with lifting the heaviest pieces I completed the job in about 6 hours over 2 days.
I am a 76 year old female with Osteo and second stage of emphysema.  I also get a lot of muscle spasms which impedes my progress. Hence the 2 days.
The instructions were easy to follow and I really like the unit.  Except for a few scratches, some yours, some mine, the only thing wrong is that the knobs are not aligned properly.
