Anyone have experience with the chairs that go up and down stairs? Can you rent them?

I'm new to this forum. My mom is 92 is currently resides in a board & care home. She is very unhappy there and very bored. She gets bummed b/c other residents are passing away. She needs interaction but is physically limited and needs a full time caregiver to assist with bathroom, dressing, bathing. Long-short, she is moving in w/us but we have a 2-story home. We have a caregiver lined up who previously worked for mom and she will live in. My husband & I work full time. I have an young adult granddaughter who also lives w/us & goes to school. Also 3 dogs & 1 kitten. I don't think she will be bored!
