great points from the other 2 reply's I have nothing to add other than to include this article from a great Vet.....

I've got a few ideas. 1) If you've recently changed cat litter, that may be the culprit. 2) Cat litter needs to be cleaned every single day. Cats are very picky creatures. Try cleaning them every day and see if this helps. 3) Do you have 3 cats? As a rule of thumb, you need one litter box for every cat, plus one extra box. From your post, you said that you have 2 litter boxes down stairs, If you have none upstairs, try to put one upstairs.
Hope these ideas help and your kitty is not suffering from a medical issue.
Hi Schaefs,
Yea, I just hate when that happens. I'm a senior too, and sometimes it just happens. Although, picking one's spot isn't usually a luxury when it is incontinence
Cat's (God Love them) usually have a reason for their behavior. It is their way of talking to us. So it seems like your kit has something to say, and he wants to make sure you hear him so she has picked someone's favorite chair.
You seemed to have covered all the usual suspects, you may need to consult with your vet. Perhaps you can call the office, explain the situation , and they can come up with an answer without having your kitty be seen by the vet.....but if it is a medical issue , I am afraid you have no choice. I am sure you do not want to have her in pain, right?
Others here may know more, so see what happens today.
Good Luck and let us know what you find out. It helps all of us.
