It does contain chemicals known to cause cancer per “California's Proposition 65“, not disclosed on the website description like it is for most of wayfair products, most which have this warning in details.  I bought because I assumed it didn’t have this, am stuck now.  Also, no predrilled holes and this is not in the description.  The first hole was diagonal and required the right angle to achieve flush.  Annoyed the instructions were not clear.  Wayfair customer service is terrible if an issue comes up, 5 times contacted and you get a different answer each time for a return.  Overall the Wood feels sturdy, and I’m sure once I can get my husband to drill holes it will be nice.  Minus whatever chemicals cause cancer per California...?!?
