This is regarding our 98-year-old Beautiful Mother😇

As far as falling out of bed, we use this rail from Amazon.
“Able Life”
Extend-A-Rail”

The link below shows one that may be even better for your needs: I attached the Amazon link.

“Stander EZ Adjust Bed Rail, Adjustable Senior Bed Rail and Bed Assist Grab Bar for Elderly Adults with Organizer Pouch”

You will need some help putting it on. You need to lift the mattress to place the straps that secure it.

It’s been a life saver.
When it’s extended to full length, we place her portable toilet at the end to give an extra extension. We have some Christmas bells attached to the portable toilet, so that every time she try’s to get up we can hear it and go help her get out of bed.

Please, let me know if this helps anyone.
