EMBRACE COMPLETE DARKNESS WITH zDEN

Did you know that light is one of the most harmful factors impacting sleep quality? Even subtle glows from electronics like a nightlight, clock, or phone charger can actively disrupt your sleep. Your body is designed to rest in complete darkness, and any light in your sleep space can interfere with crucial sleep hormones and cycles.

While blackout curtains stop light from outside, they can't block the constant, intrusive glow from all the devices and subtle sources inside your room. That's where zDen comes in.

zDen is your personal light-blocking sleep sanctuary. Its innovative blackout design surrounds your upper body, actively blocking over 99% of all sleep-disrupting light. This guides you to the deep, restorative sleep your body needs to thrive, day after day.

But it's not just about complete darkness; it's about your comfort and safety. Our breathable, OEKO-TEX® certified non-toxic fabric is exclusively crafted for zDen. The flexible frame moves with you so it won't disturb your sleep, and it's free from sharp edges or angles. These features ensure your sleep retreat is both effective and safe.

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.
