## Abstract

The present invention discloses a novel design of the height-adjustable travel pillow that provides head cushioning, and lateral support and stays in place when the user is in a seated position or semi-reclined. The travel pillow includes an inflatable system in its core which allows the user to achieve the desired thickness level to ensure maximum comfort and rest to the user.

## Claims

### Claim 1

A height-adjustable travel pillow comprising:
a U-shaped body including two arms and a back section made from memory foam or viscoelastic polyurethane foam, wherein each of said arms is molded and manufactured to have:
a concave shape on a bottom of each arm that allows the pillow to fit over a shoulder area of a user and provides positional stability for the pillow in relation to the user's shoulders and head such that the pillow will not rotate, twist, or inadvertently move out of position, and
a concave shape on a top of each arm that allows the user to wear headphones or other larger fully enclosed ear covers without the pillow pushing the headphones out of position on the user's ears;
an inflatable bladder positioned within a central portion of the U-shaped body and embedded as a middle layer between upper and lower layers of compressible foam within the body, the bladder being:
positioned and embedded within the body, and not designed to be removed or replaced by a user,
configured to expand primarily in a vertical direction upon inflation to increase the overall height and firmness of the pillow and provide enhanced head support, and
manually inflatable by a user having a protrusion that extends past an edge of the pillow for direct user inflation;
wherein the inflatable bladder is integrated such that the pillow maintains its basic functionality when the bladder is not inflated;
wherein the central portion of the U-shaped body specifically houses the inflatable bladder to provide height adjustment; and
wherein the vertical expansion of the inflatable bladder increases the height of the pillow.
