I needed a new piece of foam for the inside of my wheel chair  cushion I 
rang RGK where I bought the chair and they asked me if I wanted it hard, 
medium or soft . Is there really any difference to whether they prevent 
pressure sores or not . TIA

Yes, a hard cushion is more likely to cause pressure ulcers because the 
pressure would tend to be concentrated in a smaller area of skin, therefore 
the pressure would be higher than if it were dissipated over a wider area.

In my experience it's more complicated than just hard/soft. I tried
three different foam cushions. None of them solved the problem. I have
some feeling in my buttocks so I know if something is going to give me
trouble. I'm now using a jel filled cushion which seems to help more
than foam filled ones.
