I purchased the full size in this bed.  I put it together by myself.  If you are a woman and are handy with a hammer and screw driver you can put this together.  Be patient and take a couple breaks.  I did it by myself in two hours.  I still have to put my drawer together but that won't take long.  
I love this bed.  I actually put my sleep number platform and mattress on top.  I am a tall person so this works perfectly for me.
