never heard of a such a thing.... so I can only guess. And my guess is: I'd hate it... too restricting. I toss and turn... badly... being restricted AT ALL I have to believe would drive me whacko.
Which brings up... my biggest sleep necessity... a full length body pillow... to wrap a leg over. I simply cannot sleep well without one. On my backpacking trips, unable to take along a full length body pillow, I have to improvise or no sleep for me. I've used my backpack... tree limbs, piles of pine needles (it takes MANY and gathering them is a LOT of work), and anything else that I can improvise. When I stay at motels, or hotels, I rate them by how many pillows they give you and my ability to stack them to make a full length body pillow... I don't care about amenities... shampoo, a fridge, a microwave, TV channel selection, mints under the pillow, or even cleanliness - - - just give me pillows.
