Our Story

Hi, I’m Danielle Fujii, and I created zDen because I needed a better way to rest during migraine recovery.

I learned quickly that darkness mattered, but the options I had did not solve the whole problem. Blackout curtains helped with window light, but not the light inside the room. Sleep masks were uncomfortable for me. I wanted a simple way to create darkness anytime.

That personal need became zDen.

What I did not expect was how many other people needed a similar solution. People began using zDen for night shift sleep, shared rooms, dorms, travel, CPAP comfort, sensory sensitivities, naptime, migraine recovery, and busy homes where one person needs sleep while the world around them is still awake.

That is what guides zDen today.

I care deeply about the details because sleep is personal. When people are tired, recovering, overstimulated, adjusting to a new schedule, or trying to rest in a space they cannot fully control, better sleep can feel out of reach.

My goal is simple: to make quality sleep more accessible to everyone.

Here’s to better sleep, anytime, anywhere.
