A reviewer wrote that her 10-year old daughter put the bookcase together for her.  That's a lie and irresponsible of the reviewer to write that.  The shelves are VERY HEAVY and a 10-year old child -- especially a girl -- cannot handle such weight and risks serious injury doing so.  If you allow a child to attempt that, any injury caused will be on you for believing that lie.  DO NOT ALLOW ANY CHILD TO EVEN TRY TO ASSEMBLE IT FOR YOU!!  DO IT YOURSELF OR HAVE ANOTHER ADULT DO IT OR HELP YOU, BUT CERTAINLY NOT A CHILD.  In addition, there are many long very sharp nails to handle and trust me, that is not work for a child to do!!  I think Wayfair should remove that part of the review.  I'm shocked they allowed it.  Since 9 people said the review was helpful, it is misleading people to thinking a child can put it together.  They can't.  Period.
