This product is NOT what it says it is.  There is NO lip as described.  Wayfair should remove this product from their line this is FALSE advertising.  I contacted Wayfair first when they delivered this product to an old address. (When I ordered I selected same as billing) I had to have this product delivered to another state. I just got it 2 weeks ago.  I called Wayfair (they still have my old address despite the conversation to update the account info) and they said past 30 days to call the manufacture?? I asked to speak to a manager, she repeated call the manufacture.  Called the manufacture and could not get through.  This seems to be a very expensive scam?? Very Dissatisfied!!
