[Highland Park] Need a tub chair

Folks, An elderly woman in our church is in need of a tub chair so she can sit in the tub.....does anyone have one they can give or sell? Does anyone know of a used medical supplies place that I could purchase one if no one has one for sale? This woman is in her 80's and is being taken care of by her mentally challenged daughter....the daughter just asked me if I could find this for her mother, so I want to do all that I can to help. thanks. I will be grateful for any leads. Martha Schaefer 412-363-5821
