Is the Pillow Cube Worth It for Side-Sleepers?

At Wirecutter, we’re as curious as everyone else about the things that take over our social media feeds and promise life-changing results with a tap of the screen. The latest irresistible trend to come our way is the Pillow Cube, a square foam pillow for side-sleepers. And we wanted to see how it compared to the scores of pillows we’ve tested in our bed pillow and memory-foam pillow guides. We bought two Pillow Cube Pros to try, and we reached out with questions to two physiatrists: Dr. Akhil Chhatre, director of spine rehabilitation at Johns Hopkins in Baltimore, and Dr. Jonathan Kirschner (who’s helped us with pillow guides before) of New York City’s Hospital for Special Surgery.
