Embrace science-backed darkness

Even a tiny glow from a nightlight, charger, or digital clock can disrupt your sleep. Your body is wired to rest in total darkness, but most bedrooms stay lit with subtle, sleep-interrupting light, especially from within the room.

Blackout curtains help, but they can't block the glow from your electronics. zDen does.

zDen creates a personal sleep sanctuary that surrounds your upper body and blocks over 99 percent of all light. Its breathable, OEKO-TEX® certified non-toxic fabric and flexible frame are designed to move when you move, for comfort and safety. This is the darkness your body needs to reach deep, restorative sleep.

Transform your sleep

It’s easy to forget how much sleep shapes your life until you finally experience quality rest.

Waking up refreshed changes everything. You have more energy, more focus, and more patience to handle whatever the day brings.

In a world full of stimulation and constant input, quality sleep gives your mind and body a chance to reset. It supports memory, mood, and immunity. It helps your heart, muscles, and nervous system recover. When your sleep is consistent and protected from light and disruption, you feel the difference.

zDen helps make that kind of sleep possible.

When sleep feels harder than it should

Maybe your room never gets dark enough. Maybe your schedule is upside down. Maybe your body just needs more support to feel truly rested.

zDen is here for all of it.

Whether you are sensitive to light, recovering from migraines, working night shifts, or sleeping in a shared space that makes consistent rest difficult, zDen helps create the conditions your body needs for relaxing, restful sleep.

It is for people who:

  • Wake up tired, even after a full night of sleep
  • Work the night shift, care for others, or manage naps in busy homes
  • Share a sleep space or dorm with different sleep schedules
  • Travel frequently and struggle to rest in unfamiliar environments
  • Are light sleepers or live with sleep disorders
  • Experience migraines or light sensitivity
  • Are neurodiverse and benefit from a calming, distraction-free sleep space
  • Simply want consistent, higher quality sleep without sleep aids

Better sleep is not a luxury. It is a reset your mind and body deserve.

Why zDen is a better night's sleep solution

The science behind zDen

"Exposure to even moderate ambient lighting during nighttime sleep, compared to sleeping in a dimly lit room, harms your cardiovascular function and increases your insulin resistance the following morning."
— Northwestern Medicine study

zDen's effectiveness is based on the principle that blocking out all light sources promotes better sleep.
