My Mom is 96 but still very mobile. She can potty herself w/ the use of a cane or walker most days. She sleeps in a twin bed and tends to on the very edge. One time she fell out and ended up w/ her head in between the bedside table and her bed. (no real damage but shock fear etc) So I've taken a sofa cushion and put it in between. I walked in today and her arm was off the bed and head on the cushion. I went over and instinctively went to move her back up one the bed. Well that pretty much freaked her out and she scratched me up a bit with her nails. No ones fault really. I probably should have woke her. shrugs. Anyway now I'm looking again for something to keep her off the edge of the bed. ( no she wont let us move the bed side table closer. It has her alarm button on the side there anyway for her to use) So, I was looking at wedges or something and came on those reading pillows with arms . Has anyone used these for that purpose? What was the outcome?
