Love this shelf in our half bath.  No written instructions but easy to assemble if you follow the (picture) steps.  Manual screwdriver was all that was needed.  One thing to note.  None of the pictures show this, but this unit has hardware that is used to secure to the wall on top, which needs to be flushed against the wall or placed on top of baseboard so that it can be flushed against the wall.   We decided not to secure it because you can see the hardware.  Even though it has adjustable feet, the unit does not balance on its own.  I decided to add a decorative piece on the bottom so that it doesn't tip over.  Otherwise, it is solid wood and well constructed.
