need cushion?

Check out Supracor. Cushion support via a multitude of honeycomb-shaped cells. Seems fantastic. Definitely pricey.  Ideally for medical applications, such as for those who must spend large amounts of time sitting (i.e. wheelchair-bound).  Photo here is of a pillow from their "Lifestyles" collection, but they have a variety of seat cushions in their medical series. If you know someone who needs a really good cushion, Supracor might be worth a test drive.
