I purchased this item by phone as I wanted to ensure a delivery date. I was assured by the employee that I could choose my delivery day once confirmed by the courier Evri, but this was not the case and they advised of an earlier delivery date.
I called Wayfair again and spoke to a very helpful employee who sent a message to the courier  NOT to leave the item ( mattress) outside. She also assured me that the item would be returned and that  I need not worry and didn’t not need to call Wayfair again as it was sorted.
But, the item was delivered and left outside the property, even though a signature was required, no signature was obtained and the parcel was damaged. ( photo obtained)
I called Wayfair once again, and again a very helpful employee told me that a collection was arranged and I need not worry. 
But the item is still there as the courier could not gain access.
