What makes mellow different

Switch

Active-Feedback is our therapy we have developed where the process of the vibrations are personalised to you based on your physiology and behaviour.

10 sleep sensors
in the switch, sensors provide information about your sleep and lack of sleep to the hub for as long as you hold it while trying to fall asleep.

Button
The top switch button is designed to be pressed with your thumb when a haptic cue is felt. Waiting for the cue and responding focuses the mind, effectively switching off distractions.

Haptic cues
the switch vibrates at set intervals and a low level, determined by app data and sleep sensor analysis.

Ergonomic design The switch is designed to fit comfortably into your hand. The ring slips over your forefinger to hold it in place as you fall asleep.

Robust.
The switch is reinforced. You can take it to bed, roll on it, and it won’t damage it. It’s smooth and rounded, so it won’t dig in if you roll on it in your sleep.

Easily charged
Plug the switch into the hub to charge it. It’s as simple as that. Plugging it in downloads the date and uploads the next sleep routine.
