It took me forever to put these together (I bought 2). At one point you do need an extra pair of hands, but mostly I did with 1 person.  I appreciated the extra screws and cams.  The instructions were sometimes difficult to understand (I am a seasoned furniture assembler), and at one point I thought I was missing pieces, but in the end figured out that you had to apply the drawer runners to both sides of one piece.  They look great and hold a lot of stuff.  They are a bit wobbly to move, so once you assemble and place them where you want, just leave them be.
