Other uses for this?

This was gifted to my from my well meaning MIL. I know that these after market head rests are not necessarily safe to use in an infant car seat/carrier. I don’t want to just throw it away since she’s coming to visit after the birth, so I know she’ll ask about it. What else can I use this for ? I was thinking of putting it on the changing table (because I’ll probably never use it, my husband insisted on having one).
