I put this product together, by myself, in a few hours.  I would recommend organizing all pieces and materials before starting the process.  I would also suggest two people put this together--I was able to prop parts up on chairs as I screwed in the other side, but it would work better if two people completed this.  The trundle is on wheels, but there is no catching system, so the trundle can continue rolling out (does not fit tightly under bed).  

great value, good looking
