"Difficulty using the toilet independently"

I recently visited the GP with my elderly mother who is a wheelchair user (and also had a hip replacement and struggles with mobility and transferring from seating to standing.)

The surgery has an accessible toilet. However, although there is lots of space in the bathroom and handrails on both sides of the toilet, it is still difficult for her (and I suspect others) to use this independently because the toilet is so low and she doesn't have enough upper body strength to pull up from such a low seat using the handrails.

I was wondering whether you would consider getting a raised toilet seat which can be attached (and easily unattached for cleaning). This would make a world of difference and actually be even more accessible, as there are many non-wheelchair users that have mobility issues. And it would be a relatively inexpensive one-off cost

Thank you
