I have a pillow graveyard in my guestroom. This is the one I have now and the one have used the longest so far. Is has to air out for a few hours, is not actually "memory foam," and the filling is adjustable. It's the least "fancy" and cheapest pillow I have, but paired with a silk case it's working for me.
