My sister hunted down a few things, double handed china tea cups was one when Mum struggled to hold cups single handed without tipping etc. Came with saucer in plain white china rather than earthenware etc.
Super grippy bathroom large mats - so cover a large area and you don't have to have several/cause a trip hazard. Had cold bathroom tiles and she often needed to fully undress etc.
We also got a water heater rather than kettle and wish we had got this years earlier to let Mum embedd how to use it in her subconsious - was so much safer.
None slip trays for lap or bed eating. Tray table for bed with said none slip tray.
We also had our own slip mats for moving and turning and were taught how to use them, plus we used absorbent mats under sheets to save on washing etc, if you use disposable, the puppy mats are cheaper and work just as well, but we bought some kids ones that were wash and reuse - saved the mattress a few times.
We were also careful about the clothes we bought so that they were easy for us to put on and Mum to manage - so no massive over the head clothes - stuck to wraps, zips and larger buttons etc
Mum also had an Alexa - called it "my little computer" she enjoyed having it and
it amused her almost to the end with giving a weather forecast specifically for her small town. Could have been used for alot more - reminders, day and date reminders, books, music etc but we never really got to setting it all up to be more automated and her attention span rapidly reduced. She used to like music from her parents era as we think it was linked with her childhood in her mind which she didn't have too much trouble remembering.
