Source of the cute blanket emoji image of this community?

I had not heard of a weighted blanket until I saw that image and searched for what it might refer to. Are they useful for adults too? Will ask my ADHD friend if they ever had one, might make a good gift.

The image looks like it could be used as a real emoji (expressing comfort). Who made it? I would like to use the image if permission has been given (e.g. Creative Commons licence).
