My assembly  man was wonderful  and spoke fluent understandable when speaking English.  
Was disappointed when he was on his phone and ended up putting a few parts in backwards and had to take it apart and rebuild.  In which he did no proble,.  I was impressed with the efficiency and speed of putting this piece of furniture.  He was very polite, he even saw that we took off our shoes upon coming in front door so he also took off his shoes, that 
Made my day to begin with.
