This is the ComfyBreasts Relaxation System. It's a full body pillow with a hollowed out section to rest your breasts in and relieve pressure on them. Because remember ladies: a comfy tit is a happy tit. Also: a boob in the hand is worth over a dozen in the bush.
The ComfyBreast pillow is currently a Kickstarter campaign and I read through the info they provided which had little to no scientific data to suggest a pillow with a boob hole is beneficial to a lady's knockers. But the pillow was tested on two different women, who had this to say:
Tester #1: "Thought it was a Dream Pillow - Very Comfy." and Tester #2: Said she could fall asleep easily, and actually almost forgot she had breasts.
"ACTUALLY ALMOST FORGOT SHE HAD BREASTS." Now that's a magical pillow. It's a shame they don't make a guy version because I'd be curious to know what it feels like to fall asleep without a penis. "So...a pillow with a hole to rest your pecker in? That sounds like a cheap love doll." I'm realizing that now.
