I have ordered many things from Wayfair that I have put together.  Each one previously turned out to be a beautiful piece of furniture.  The wood in this cabinet was of a cheap grade.  I never have had a problem putting anything I bought together but the cams with this unit were horrible.  Even with the back on it is still not very sturdy.  I had to add angle brackets under each area just to help stabilize it.  I would not recommend this unit to anyone.   I should be given money back for the extra effort that went into putting this cabinet together.
