TravelRest is a patented-shape inflatable travel pillow built primarily for sleeping seated in transit — on a plane, bus, or train. Unlike a classic horseshoe neck pillow, it provides lateral head and neck support, addressing the common complaint of the head sliding sideways while dozing against a window.
At 145 g and inflated to 66 × 20 cm, it's larger and heavier than minimalist tent-sleeping pillows, which fits its purpose: it's a travel accessory rather than trekking gear. Deflated, it rolls down to a compact 8 × 23 cm and attaches to the seat headrest with an included tether cord so it won't slip. For hikers, it's more useful on the journey to the trailhead than as part of an in-the-field sleep system, where lighter inflatable or hybrid pillows do better. It's available in several colourways; blue and grey are listed here.
