I found out that the best for myself as a therapist and the client is to get them to sit up on the bed or couch, my bed is quite comfy not just a plinth. Clients I insert the leg rolls and cushion and warned blankets so they all snug and cosy, and for my own back its at the correct height.
As you get older I battle to do them on a chair now days 10 years into this job[emoji85] and few car accidents later [emoji17].
