A New Pillow Uses NASA Technology to Deliver a Good Night’s Sleep

Forget Ambien: The Simba Hybrid may put you fast asleep even faster. The surface shell features Outlast, a proprietary coating material originally developed for NASA to protect astronauts from temperature variations. Instead of flipping it to the cool side, this £95 ($123) pillow will prevent you from sweating in the first place. And rather than a single wedge of springy material, it’s filled with Cheeto-shaped, laser-cut foam tubes that adjust as you move during the night, allowing trapped air to circulate so the surface stays cool.

• Hibr (as in “hibernate”) offers $99 pillows that also feature temperature-regulating foam. They come in two shapes, for side or back sleepers, which may feel limiting for those who prefer versatility.
