ABSTRACT:
An apparatus and a method are disclosed for cushioning and maintaining an object by a device having a quantity of granular material that is located in a retaining element. The retaining element is divided into compartments which contain the quantity of granular material. The retaining element and the granular material are located within an inner volume of a sealed housing. The retaining element is made from a material that is permeable to gas, but impermedable to the granular materials, while the sealed housing is made from a material that is impermeable to gas the effect of such compartmenting is to keep the granular material in place within the retaining elements, even when the housing is at atmospheric pressure in order to preserve a constant thickness of the device.
