Height adjustable/low seat height wheelchair

HI, My mam has osteo-arthritis resulting in limited mobility, lives in a care home and uses a wheelchair which needs to be replaced. I’ve been looking for a self propelled wheelchair which also has a low seat height (less than 46cm/18in) to allow her to propel using both arms and feet but am struggling to find one. Has anyone any recommendations? Or suggestions where can I get advice?

Ask Social Services or the doctor to arrange for an occupational therapy assessment. Should be available free.
