The Sleep of Your Dreams

According to the Centers for Disease Control and Prevention, a third of us don’t get nearly enough shut-eye. Our collective tiredness has promoted a $41 billion market for devices promising more — and higher-quality — sleep. In my everlasting search for downtime, I tested some of the most promising ones. Here’s how they stacked up.

Eight sleep tracker

$299

This mattress (床垫) topper fits under a sheet and “turns any bed into a smart bed,” according to Eight. While I slept, the sensor-decorated pad gathered data like heart rate, periods of deepest sleep, and number of turns. It was easy to use, and I liked the warming feature, which let me set each side of the bed to a different temperature.

REM Score: 8 (out of 10)

Dreampad pillow

$149 and up

The Dreampad uses smooth soundscapes to help you power down. Connect the device to your phone via Bluetooth or USB, and the pillow emits soft music, audible only to you as you lay your head down. There are ten tracks on offer. I didn’t drift off any faster with the Dreampad, but it did help me fall back asleep when I woke up at night.

REM Score:6

Smart Nora Wireless Snoring Solution

$299

My eight-hour restful happiness is frequently interrupted by my husband’s snoring. The Smart Nora relieves me of the need to push him. When the bedside audio sensor detects a breathing disturbance, it slowly blows up the offender’s pillow, gently shifting them into a freer-breathing position. My husband sometimes woke up briefly but was soon asleep again.

REM Score: 9
