The build is straight forward and can be done by one but would be easier with two.  A  hammer or rubber mallet might make inserting the wooden dowels easier.  Note that the wood is completely unfinished.  That is great if you want to do the work to get it the right color for you, but not so good if you like the color in the picture and were hoping to have it look like real furniture.  A rub on finish would work fine.  There is no center support as there is i every other queen size platform frame I have ever had.
