Yes and no. It does change as your position changes, but you'd have to be pretty changed to make a real difference. But if you saw the pressure difference on my mapping of my Jay and my Roho, it was clearly more relief on my Roho. I was able to see how the pressure changes as I raised and lowered my leg-rests. I could tell where the best location was. Even if I'm slightly on one butt cheek more than the other or off to one side a bit. One day may fit better than another, but averaged out the better your cushion fits you the better for your butt. If I was 1 inch off, I'd be pretty uncomfortable. I think that would be bad on your butt with any cushion. Just my thoughts. Greg
_____ As I've posted previously, I question the true value of pressure mapping. Doesn't the process and mapping assume you will always be seated (positioned) exactly the same way in your chair on your cushion each time? It seems even a minor variance (perhaps 1") left, right, forward or backward would effectively change the mapping. There may also be variances due to types of clothing worn and changes in weight.
