In some examples, the travel pillow includes multiple segments of inserts to allow a varying thickness across different portions of the travel pillow. In still further examples, the inserts themselves may vary in thickness. ## Claims ### Claim 1 A travel pillow that is thickness adjustable, comprising: an exterior cover that forms an interior cavity, the exterior cover in a substantially horseshoe shape; a first insert disposed within the interior cavity, and shaped to fit within and fill a first portion of the interior cavity; and a second insert removably inserted into the interior cavity, and shaped to fit within and fill at least a second portion of the interior cavity, the second insert being substantially disposed upon the first insert, wherein inserting the second insert modifies the overall thickness of the travel pillow. ### Claim 2 (depends on 1) The travel pillow of claim 1, wherein the exterior cover is comprised of a material that can expand to accommodate varying sizes of second inserts. ### Claim 3 (depends on 1) The travel pillow of claim 1, wherein the first insert is constructed from a viscoelastic foam. ### Claim 4 (depends on 1) The travel pillow of claim 1, wherein the second insert further comprises a plurality of inserts. ### Claim 5 (depends on 4) The travel pillow of claim 4, wherein each of the plurality of inserts is inserted into a different part of the interior cavity, and is disposed upon the first insert when inserted into the interior cavity. ### Claim 6 (depends on 5) The travel pillow of claim 5, wherein each of the plurality of inserts modifies the thickness of a different section of the travel pillow. ### Claim 7 (depends on 1) The travel pillow of claim 1, wherein the second insert is constructed from viscoelastic foam. ### Claim 8 (depends on 1) The travel pillow of claim 1, wherein the second insert is constructed from an inflatable bladder. ### Claim 9 (depends on 1) The travel pillow of claim 1, wherein the exterior cover includes an outer surface that does not irritate the skin of the user. ### Claim 10 (depends on 9) The travel pillow of claim 9, wherein the outer surface of the exterior cover is made from fleece. ### Claim 11 (depends on 9) The travel pillow of claim 9, wherein the outer surface of the exterior cover is made from microfiber. ### Claim 12 A travel pillow that is thickness adjustable, comprising: an exterior cover that is substantially horseshoe in shape and that forms an interior cavity; and one or more inserts that can be removably inserted into the interior cavity; wherein inserting the one or more inserts modifies the overall thickness of the travel pillow. ### Claim 13 (depends on 12) The travel pillow of claim 12, wherein each of the one or more inserts is inserted into a different part of the interior cavity. ### Claim 14 (depends on 13) The travel pillow of claim 13, wherein each of the plurality of inserts modifies the thickness of a different section of the travel pillow. ### Claim 15 (depends on 14) The travel pillow of claim 14, wherein at least one of the plurality of inserts is made from viscoelastic foam. ### Claim 16 (depends on 15) The travel pillow of claim 15, wherein the exterior cover is comprised of a material that can stretch to form-fit over the one or more inserts when the one or more inserts are inserted into the interior cavity. ### Claim 17 A travel pillow that is thickness adjustable so as to accommodate varying positions of a user, comprising: an exterior cover sized to fit around the neck of the user, comprised of a rear section to fit behind the user's neck, and two side sections contiguously disposed to the rear section that each fit on one side of the user's neck; an interior cavity formed by the exterior cover, the interior cavity comprised of a rear cavity portion and two side cavity portions corresponding each to the rear section and two side sections of the exterior cover; a first insert that fits into each of the cavity portions of the interior cavity; and one or more second inserts that each removably fit into one or more of the cavity portions. ### Claim 18 (depends on 17) The travel pillow of claim 17, wherein the one or more second inserts alter the thickness of each cavity portion into which each of the one or more second inserts is removably inserted. ### Claim 19 (depends on 18) The travel pillow of claim 18, wherein each of the one or more second inserts is comprised of viscoelastic foam. ### Claim 20 (depends on 18) The travel pillow of claim 18, wherein at least one of the one or more second inserts is comprised of an inflatable bladder.
