Abstract: A pillow formed by a folded over foam substrate, has attached at its respective distal end an openable inner compartment. The inner compartment can be filled with variable inserts for back of head and neck support, wherein the inserts includes loose fibrous materials or loose pieces of viscoelastic foam, either loose or in discrete closed pouches. This utilizes the softness and support of the materials, to individually vary the softness and support as the user of the pillow chooses. This promotes interchangeability of the interior pillow materials. The pillowcase may include an internal opened sleeve at one end of the pillowcase, to enhance the ease and speed of inserting pillows within pillowcases, with extra manual shoving and manipulation.

Abstract: A support pillow has a pillow-fill unit comprising pillow fill material, a neck support unit comprising an inflatable air bladder and a pillow case having a first sleeve for receiving the pillow-fill unit and a second sleeve for receiving the cervical or neck support unit. The second sleeve of the pillow case includes padding on an inner sleeve surface. The inflatable air bladder includes a valve that operates in a first state to allow an input of pressurized air and in a second state to allow an exit of bladder-stored air. Adding air to the inflatable air bladder, in the first state, increases a size of and pressure in the inflatable air bladder. Also, the padding on the inner sleeve surface of the second sleeve is soft, and compressible.
