When the day's agenda calls for planes, trains, automobiles and maybe a ferry for good measure, preempt uncomfortable seats with the First-Class Travel Cushion. Its anti-slip bottom fabric keeps the cushion in place, no matter how jarring the ride, and its ergonomic shape, curved rear edge and variable density foam core provide welcome relief for your Ischial (seat) bones. A self-inflating design provides one-hand adjustment that minimizes weight and packs small, rolled or flat, making it easy to bring along.
