When you are not the patient but go to the hospital to visit a loved one or friend and decide to stay the night...beware.  If you stay the night all that the hospital will provide is a bench for you to sleep on.  They will provide you with sheets and a blanket as well as a pillow but the hard flat surface will get your back to hurting and not let you get very much sleep.  So unless your loved one is in a room with two beds and do not have a roommate to where you have your own bed to sleep in, prepare for a hurting back and very little sleep to get you thru the night.
