I'd think it would be to claustrophobic for me...but one of my favorite pictures back in the old, old days was a young lady in a straitjacket face down on the floor with another young lady sitting on her rear end with the girl-in-the-jacket's feet pulled up for a good tickling.
What made it one of my favorites is that the girl who was tickling had her feet just inches from the face of the girl in the jacket. And I can imagine the girl being tickled being so frustrated that she could see those tempting target, perhaps an avenue to escape her own torture, but could do nothing due to wearing the jacket.
Wish I still had that one.
