THREE PILLOWS THAT TAKE THE PAIN OUT OF SNOOZING ON THE PLANE.

U-shaped memory foam travel pillows hang around many a carry-on bag, but do you really like dragging those around? Plus, they push your head uncomfortably forward when you try to lean back, leaving some travelers with more neck pain then they may have started out with. We napped excessively, uh, tested these pillows for comfort and packability, just in case you’re looking for a replacement.

Sea to Summit Aeros Premium Traveler Pillow

What we liked: The large side arms provide plenty of neck support, and the thin center doesn’t apply pressure to your neck when pressed into a headrest. The inflatable pillow packed into its carrying case takes up much less space in your carry-on. Not so much: When the airplane cabin is dead silent and you’re blowing up your neck pillow, you may feel as if you’re making a lot of noise (but you really aren’t).

Cabeau Evolution Cool

What we liked: The material and added air-circulation vents keep your neck cooler than memory foam does, and the magnetic clasp helps secure the pillow around your neck while you’re sleeping. Packs into the size of a grapefruit. Not so much: Petite adults may find the pillow a little large to use correctly. Vitals: Cabeau Evolution Cool, $59.99 from www.cabeau.com

REI Co-op Self-Inflating Travel Pillow

What we liked: The peanut shape offers support around the sides of your neck, and the silicone strips on the back keep it from slipping around. This pillow self-inflates in less than five seconds. Rolls up small in included stuff sack. Not so much: Not as comfortable as some others in a lie-flat sleep environment. Vitals: REI Co-op Self-Inflating Travel Pillow, $19.50 from www.rei.com
