Will STILL work with my bed?
STILL works with most mattress types and thicknesses, with a suitable bed base and placement. It isn’t suitable for waterbeds or mattresses with water bladders. Check your bed type before ordering.
STILL

Heart rate, breathing, and movement, recorded beneath your mattress.
Design
STILL keeps things simple. A small sensor beneath your mattress, with less to manage each day.
Drag to rotate
Fits beneath your mattress, with nothing to wear and no bedside space taken up.
Once the plate is in place, STILL attaches magnetically and lifts off when needed.
STILL stays connected to USB-C power, with no battery to recharge.
STILL focuses on recording. A small light shows it’s powered on and helps you identify it during pairing.
