It appears that you are using able-bodied people to demonstrate the hand check on the Roho cushion. I think you should use somebody will spinal-cord injuries, preferably a tetraplegic who doesn't have much movement. When you're not able to help the person checking your cushion by rocking or lifting your leg it's very hard for them to get their hand right under your backside

It doesn't work any better than a Memory Foam cushion. After 4 hours in my Roho, my butt will be red for a day or 2.
