We left our first meeting with T thinking about a chair, that started of low enough to scoot onto but could get high enough to sit up from easily. Today we did a brief search so see if there is already an adequate solution.
Here is what we found:
There are definitely chairs designed to help people get up! Unfortunately these range from 350-10,0000 dollars and none way less than 15 lb, let alone are shaped to be able to bring with you on a walk or bike ride.
Meanwhile T sent us this video, which is awesome!
