She uses a walker, sits on the side and cannot get them up. She has a bed bar which prevents her from falling out in the process, but that doesn't help her actually get her legs up. Sometimes she can get one leg up enough to use a heel to push her self further onto the bed. Sometimes she can lie on her side and bring them up to a fetal position with the help of the bar to steady herself. Would some kind of sling help? An adjustable bed?
