This product arrived much sooner than expected. The box had a few nicks in it as would be expected. When I opened it, the level of packaging was the most protective that I have ever seen. Styrofoam and heavy duty corner protection throughout. I could not find any damage.  
The assembly instructions were drawings. This is understandable due to the number of different countries, and languages that it could be shipped to.
My advice: do not start assembly on your first read through. Look at and think about those pictures perhaps a couple times. Many parts are similar but the pictures make things clear, if you take the time to look.
There are several bonus, unexpected items included. Metal clips to secure back panels, decorative covers for unsightly connectors.
I have purchased pre-assembelled  office equipment from other vendors none of them have equaled the quality of this.
