Easy on a wheelchair rider's rear end
I got this for my 104 year old dad who, for the past 2 years has been in a wheel chair and complains of his rear end being sore from sitting.  He's using it and hasn't complained in over a week so that's a good sign. It was recommended to me by someone who has been in a wheelchair for close to 20 years and is a nursing home director.
