Can anyone give me any advice on the above subject? I need a special riser/recliner for my mother who now needs to be hoisted. She has no mobility at all now, and sits and sleeps, staying in the same position. I have tried one with an integral airflow pump for pressure relief but after an hour or so she found it uncomfortable. It was a Repose C-air tilt in space riser/recliner. I am willing to spend a large sum if I can find something suitable for her. Would a wheelchair-type armchair be preferable? Has anyone tried the Careflex range which our local mobility shop supplies?
