Wendy has arthritis in her lower back so I am familiar with the problem. I want to do a gel insert in her seat just haven't gotten the materials yet. I did do floorboards and pull back risers and they both helper her a great deal by changing her seating position. She isn't reaching forward for the bars now and the floor boards let her move her feet back but allow her to move them back forward to change where the pressure on her back is.
the 2nd shot is the best I have showing the floorboards to give you an idea the range of foot position.
