Headrest clip removal

I'm thinking of doing an interior refresh and I'd like to start by cleaning the seat upholstery. The fabric covering on the upright part of my bench seat looks like it should come off fairly easily if I can just get these clip things off. I gave it a shot but I didn't want to break them.

Does anyone know how to remove these?

 

There are several threads on reupholstering their tacos that will likely help. @HomerTaco created a detailed tutorial years ago, but it applies.

 

That's perfect, exactly what I was looking for. Thanks!

OP said he was interested in cleaning the fabric, not upholstering. Just get a Bissell, it’s easy.
