Product features & benefits

• Instantly Turn Day into Night: Create total darkness in seconds, even in a bright room. zDen blocks over 99% of sleep-disrupting light so you can nap during the day, sleep past sunrise, or recover without being woken by light leaks, nightlights, or ambient light.
• Your Private Sleep Space, Anywhere: In a shared bedroom, dorm, hotel, or busy home, zDen creates a personal “do not disturb” sleep zone for fewer distractions and disruptions.
• Built for Real Life Sleep Challenges: Sleep after a night shift, nap in a bright hotel room, rest in a shared dorm, or create a consistent sleep space for kids. zDen helps you fall asleep faster, stay asleep, and protect your sleep when your environment isn’t ideal.
• Darkness for You, Not the Whole Room: zDen blocks light from getting in and keeps light inside. Read, use your phone, or wind down without lighting up the room or disturbing others. It also allows for nightlights or hallway lighting for safe navigation while maintaining a dark, private sleep space.
• Spacious, Safe, and Easy to Use: Designed to comfortably fit your upper body, zDen measures 30" L x 24" H x 24" D and fits up to a queen-size pillow. Ready in seconds with no assembly. Sleep Doctor approved, CPSC compliant for ages 5+, and made with certified non-toxic materials. Includes CPAP-compatible pass-throughs for added sleep support and migraine recovery.
