Best for stopping your head dropping sideways
Trtl Pillow Plus
An internal plastic brace inside a fleece wrap. Supports the side of your head, which is the point.
This is the pick because it addresses the actual failure mode. Your head does not fall backwards when you doze upright; it falls sideways, and a U-shaped pillow behind your neck does nothing about that. A shaped internal brace against the side of your neck holds your head up, which is what lets you sleep. It also packs flat rather than as an awkward ring. The fleece is warm and you commit to one side, both of which are genuine but modest costs.

Good for
