The unit is sturdy.  It came with wall anchors that I chose not to use as I am a renter.  Should be ok if I place heavier objects on the lowest shelves and not the top.  I chose this item because it has a cross brace near the bottom for added stability.
Assembly took about 1 hour.  It came with the tools needed.  The screws and bolts were substantial.  All of the predrilled holes lined up.  
The wood grain finish is paper laminated on pressed board.  It is attractive, but the least durable part of the total design.  
I recommend this item.
