    Abstract: A self-inflating support device or cushion (10) consists of an envelope (11) defining a closed space, a compressible material contained within the envelope (11) and valve means (15) adapted to allow air into the envelope (11) so that the compressed material can expand to enlarge the support device (10) and to allow air out of the envelope (11) so that the material may be compressed and the support device (10) reduced in size.
