Amended review 
Wayfair astonished me with their amazing customer service. Please note my old review at the bottom. I was refunded in full when I explained that we didn’t receive any mattress and order was showing that all items were delivered! 
A week later, when mattress turned up and we didn’t want it, I contacted the customer service again who advised that I could donate my brand new mattress to a charity or they could easily pick it up again. How very kind of them. Sooo impressed and will be ordering a lot more in future. 
Old review We ordered the bed plus mattress. Mattress was never delivered to us. Now asking for the mattress refund and they they are only offering 30 amount back. Never order mattress with the bed...! Very disappointed as have been purchasing from wayfair so much and other stuff was delivered fully.
