Seat width is as individual as our bikes, so it’s important to find the right fit for the seat cushion. If you use a wheelchair, you can use the width of your seat cushion as a guide. Alternatively, you can measure your seat width yourself as follows:
1) Sit down on a couch at one end
2) Place a large book, a box, or something similar on the other side, applying light pressure
3) Now measure the distance between the end of the couch and the object you’re using
That should give you an idea of the seat width.
