I m a caregiver. My client is 79, weighs over 400 lbs. has liver failure and his scrotum is the size of a large cantaloupe. He can t sit in a chair unless it is hanging over the front putting him in a sliding position. Is there a cushion or device made that he can sit on and have the scrotum hang below the cushion, like a horseshoe shape? I am now in the process of finding a lift chair for him and will have to have some sort of device to ease his discomfort while sitting. Thank you
