12 Smart Packing Items for Health and Comfort in Your Carry-On

7. Portable lumbar and posture supports

Airline seats vary widely in ergonomics, and poor lumbar support often leads to back pain during and after travel. A compact lumbar cushion or inflatable support fits behind your lower back and encourages a neutral spine. Choose a slim design that fits in seat-back pockets or compresses easily for storage. Lumbar supports reduce muscle strain by keeping hips and spine aligned and are especially helpful for travelers with chronic lower-back discomfort. If you have a history of back issues, test the cushion at home to find the shape and thickness that works best before bringing it on a long flight. Combine posture support with seated stretching and brief walks to reduce stiffness. Because these supports are low-profile and reusable, they’re a smart carry-on item that helps you arrive in your destination body-ready.
