Didn’t come with instructions - had to Google it - all but one of the dowels broke during assembly so it was impossible to keep it together when trying to put the final screws in; which by the way, you need a tiny screwdriver for.  A bit frustrating.  Also, and to no one’s fault but my own, it was short.  I was more concerned about width - but if you’re considering this one, if your mattress sits on the floor, this is the perfect one for you!
