Noel – thank you for the response. I’m going to find a local stockist and take her in to try it. I might also measure the width of her current one supplied by wheelchair services – she has long been due an upgrade as she’s had this since she was 13/14. She is much taller now however, but we are on a long waiting list with Wheelchair services ( been nearly two years already) who I am told are significantly understaffed.
