Some bed science...which is actually pretty hard to bring someone's attention to because for most people it's just "I sleep and that's it", lol.
I think I'll try to test out my bed at my dorm once I get back with the help of a timed camera or my roommate, thanks for the awareness raising post :)
Exactly most of the people just sleep on whatever matress - only few who get spinal pains tend to check on what they are sleeping on.
Though, being aware and keeping a check can help a long way.
