Last week, I heard a thump and wondered what it was. Did the usual check for burglars, then thought no more about it for half an hour. Then I noticed my 92-year old dad's bedroom light was on, and when I went in there was blood all over the place and he was struggling to breathe and in pain. It turned out he'd rolled over the wrong way, fallen out of bed, and landed on a bucket (you can guess what that was for). He'd ripped his arm and landed across the bucket on his side. I had to take him to A&E at 3.30am - in a taxi, because there were no ambulances available. I had to go home at 5am, worry until 9am, then phone the hospital to find out what was up. He'd broken two ribs (plus some relevant but other stuff regarding his health). I immediately thought 'bed rail' to preclude the possibility of it happening again. A quick Google brought this device up. So I ordered it. It works. It's well made and strong. I wish I'd thought of this before, but on the other hand how could I have?
