Extreme obesity

Anyone had any irl experiences of being immobile or with someone immobile/near immobility ?

My partner's mobility has been in decline for years. Starting with needing crutches and a mobility scooter. She has continued to gain weight and can barely stand and can only walk a very short distance and now uses a bariatric wheelchair.
We both know it will not be long before she will be fully immobile and bed ridden. I am currently looking into having a hoist installed to be able to move her.
