Well it definitely isn't 10" thick as advertised, corners are maybe 6-7" which makes it lopsided and poorly made.  Shipped through FedEx which was a joke, 5 consecutive days I was notified it was "out for delivery today" and later those days received notification that it was "delayed".  I will likely not purchase through Wayfair again.  This mattress is not worth what I paid, save your money, buy something else from a different company.
