FAQ
Questions, answered.
Will the person next to me hear it?
At normal bedtime volume, the sound stays with your pillow and they won't be bothered. Turn it way up and they may catch a faint murmur, so keep it low and let the pillow do the work.
Will I feel it under my pillow?
It's slim and light, made to lie flat under your pillow without a lump. Side sleepers included.
What can I play through it?
Anything from your phone, tablet, or laptop over Bluetooth: Spotify, podcasts, audiobooks, YouTube, sleep apps.
Does it have built-in sounds?
Yes. White noise and nature sounds are built right in, so you don't even need your phone nearby.
How do I charge it?
With the included USB-C cable. The auto-off timer shuts it down after you fall asleep, so it isn't draining all night.
Can I take it when I travel?
That's half the point. It's slim enough for a carry-on or toiletry bag, and it turns any hotel pillow into your pillow.
Which color should I get?
Black disappears into dark bedding, Blue is our signature, and Blush is the softest look on a light pillowcase.
Can I mix colors in a bundle?
Yes. Add each color to your cart separately and bundle savings apply automatically: 10% off two, 15% off three or more.
