Memory foam pillow issue - too hard!

[rszdtrvl]

I purchased DH a memory foam pillow last week. Had him test it before I uncovered the plastic and tossed the box. He said it was great.

He attempted to use it that night, and said it was too hard. Like sleeping on a brick.

Is there any way to relax a hard memory foam pillow? Any hints you have?

We always use the same type, but I couldn't find them this time, so I had to get a new brand. At $20, I really don't want to toss it, and since it is out of the plastic, I can't return it either (it has been used).
