Raizer Lifting Chair

My husband has had several falls recently. Each time he has had to wait for up to 5hrs for an ambulance, as I am unable to help him up.

The Raizer M Lifting Chair enables safe single handed care and only requires one operator to turn the smooth crank handle.

The Raizer II Emergency Patient Lifting Chair is a unique patient falls response device that can be operated by a single carer to lift a fallen person from the floor in a smooth, remote-controlled mechanised motion.

I am looking for a used chair, either the M or II model. Ideally, around £1000, and in the south east. I cannot afford new.

Can anybody help, please?
