@azadviser Those mats sound terrific, but just like getting around a half rail, my brother-in-law's Mom quickly figured out how to avoid stepping on hers.
Also, there is the matter of whether it would be UL approved for care facility use.
Back in the day, my Grandma used to slip off her nightgown, which had an attached alarm if she tried to get up. Yet she could neither dress nor undress herself in the daytime.

As my daughter who spent 10 years as a Memory Care nurse said they never found a solution. In many ways, it's like trying to hide candy from a kid - I once found my 3 year old on the top of the refrigerator trying to get gum from the cupboard!

I hope someone here comes forward with a solution.
