An inflatable cushion for body support is described. The inflatable cushion can be adjusted to manually/automatically set the proper pressure distribution, remove pressure from sensitive regions, alternate pressure, facilitate moisture removal, automatically detect leakage and avoid bottom down, communicate leakage and other problems with the user/caregiver, detect wrong positioning and facilitate position correction. The inflatable cushion can be used either as a chair cushion such as for example as a cushion for wheelchair or as a bed mattress.
