Toilet safety for the vain and elderly

Are there toilet safety rails that don't look like something out of hospice care? My mother is aging, and had an injury a couple years ago that never quite healed. She can walk with a cane, but not fast, and has significant mobility issues. She's a little vain and though nobody visits her house, she doesn't want anything in her home that makes it obvious she has an injury.

Recently, she told me that it's been hard to get up after using the toilet. She wants to replace the toilet with a tall toilet. That's fine, and it's her decision, but the toilet works fine and she's on a fixed income, and replacing a toilet isn't the cheapest option. I'd never heard of a solution but I thought there was a market for some sort of safety apparatus that doesn't look like hospital equipment. Lots of elderly people have more money than mobility and would pay for their bathroom to look nice. It would have to be secure but freestanding, as the toilet isn't so strong that it could support her much longer and I'd prefer not to have to drill into the wall.

A quick search on Amazon got me "toilet safety rails" that look like they'd do the job (like this), but everything looks like medical equipment. Anyone have any ideas for something we could buy that looks elegant and nice?
