FAQ · Deep Sleep Duo
Questions? Answered.
Straight answers about the mask, the earplugs and the 40-night guarantee.
Will I still hear my alarm?
Yes, for most people. Life+ takes about 24 dB off the room (SNR 24); an alarm or a smoke detector starts far louder, so it still gets through. Very deep sleepers: put the phone a little closer, or test it one night first.
I sleep on my side. Will anything press?
No. The earplugs have no stem and sit flush in the ear. The mask has no buckle and no elastic over the ears: the Velcro strap sits behind your head, and the soft pads keep pressure off your eyes.
Does the mask really keep the light out?
It runs from forehead to cheeks and closes the gap at the nose, where light usually gets in. Wear it a little lower than a normal mask at first; most people find their position within a night or two.
My ear canals are narrow. Will Life+ fit?
Life+ fits most adults. If earplugs usually fall out or press, add the AI ear measurement: you upload a photo of each ear and we send the size that fits.
Can I pick the mask colour, and buy one for my partner?
Yes. Navy Blue, Rose Quartz or Triple Black. Choose For two and each set gets its own colour.
How do I clean the mask and the earplugs?
Mask: cold hand wash, no bleach, no tumble dryer, dry in the shade. Earplugs: rinse with water and mild soap, let them dry and keep them in the aluminium case.
When will my order arrive?
UK orders over £35 ship free, so the Duo always ships free. Order before the cut-off shown above the button and it leaves our UK warehouse the same day; delivery usually takes 1 to 3 business days.
What if it does not help me sleep?
You have 40 nights to try it. Not sleeping better? Contact us and we refund you in full.
