I chose the option of having a professional assemble the desk.  He never showed up and did not respond to messages.  I asked for a refund of the services and IF APPROVED(!) I will get a check in 3-5 weeks.  Since my partner has experience as a general contractor,  we decided to assemble ourselves,   We now think we know why the professional was a no-show.   The instructions are unclear and misleading.   Where the instructions indicate 3 screws are needed to secure drawer rails, only 3 holes were drilled.  The instructions completely omitted one of the drawer slides. After 3.5 hours, we are at step 18 of 51.   Not the way I wanted to spend New Years Eve.
