It is sort of funny the things we form emotional attachments to. Several years ago my Grandma Janet gave me this pillow from an old couch for Alexa to use on the drive home from her house. She was very concerned that she didn't have a pillow! It is totally ugly, in some horrid fabric but it was super clean (that's my Grandma for you) so I kept it and haven't been able to get rid of it.
I didn't feel like going out and buying a zipper so I just took the original zipper from the pillow.
