Somebody shared about "sleeping stalls" as a comment in my previous question. Could somebody elaborate (hopefully with a picture or some link) which tell/share more about sleeping stalls and how they are different from waiting rooms. For instance, the waiting room in Doha, Qatar International Airport was "free" but one couldn't sleep unless one had a bed-sheet or something to put underneath and were ready to sleep on the floor. The only thing you could do is to sleep on a beach-chair/recliner which is not good for obese people like me.
See Yotel for example. There are pictures in the link, but possibly are copyrighted. These differ from waiting rooms as those are usually free. 'Cabins' such as Yotel's are more akin to hotel rooms, but generally much smaller and obviously without hotel facilities such as room service.
More like a luggage locker but for people rather than bags.
There are also sleeping pods.
