It's billed as a way to sleep on busses, trains and planes.
It works simply by strapping the device around your back and resting your chin in the frame. The frame is completely bendable to fit any type of face and to fold up for easy storage.
It’s available for US$39.99 or $46.99 with the cover/bag, but I know people are still going to be hung up on superficial things like looking ridiculous.
Looks like a lot of work to get some sleep and possibly a sore neck.
I'll have to try one and see if it works.
