If you try a mattress with a dip in it, with the hospital bed

Bed alarm

Bed sensors or a low profile bed is probably the best way forward. Somebody who is reasonably mobile is at greater risk of injury if they climb over the rails. There is also the risk of entrapment (not sure what the rails look like). You could also try crash mats that go on the floor.

Oh I just know my sister would crawl over the bars and fall for sure. She is a nightmare with our recliner chairs!! I hope you find a good solution for your mom.

Thank you for all your help! We did take the box spring mattress off so now her bed is a lot lower. I believe we are going to purchase a bed alarm like suggested. Thank God she didnt break any bones!
