How dark does it get?
When the front drapes and window flaps are closed, zDen blocks up to 99% of light. It helps reduce light from common sources like clocks, nightlights, TVs, hallway light, early morning daylight, moonlight and streetlights.

Will it fit a twin, full, queen, king bed?
Yes. A single zDen can fit comfortably on a twin or full-size bed. Two zDens can fit (tightly side-by-side) on a queen-size bed. Two zDens can fit comfortably side-by-side on a king-size bed. Each zDen is ~30" wide x 24" tall x 24" deep. It is designed to hold up to a queen-size pillow inside.

Does it cover my whole body?
No. zDen is designed to cover only your upper body. Your lower body stays outside under your normal blanket, which makes it easy to move freely and exit quickly. It is 30" wide by 24" tall by 24" deep.

Do I have to use a pillow in my zDen?
zDen is designed to be used with a pillow inside, up to a queen-size pillow. The quilted bottom adds structure and stability but the pillow is what supports your head and neck. Although some users report using it without a pillow for powernaps at work or when they are stuck in the airport due to delays.

Care instructions:
BASIC CLEANING can be done using a non-abrasive sponge, cold water and a non-detergent soap. 

DO NOT machine-wash or machine-dry this product because washers and dryers can stretch, damage or tear fabric, mesh and seams. 

DO NOT use household cleaners or harsh dish soaps, bleach, spot removers or laundry pre-soaking products may ruin the fabric on this product.

Can I use zDen with a CPAP?
Yes. zDen is CPAP friendly and includes two pass-through openings, in the back bottom corners, that can be used to route a standard-size CPAP hose (or a charging cable) while keeping the sleep space dark.

Can I sit up inside it?
zDen is designed for sleeping and resting while lying down with a pillow. Although, you can be partially propped up with two pillows to watch TV or read a book.

Does zDen reduce noise too?
zDen is designed to block light. It can slightly dampen sound, but it is not soundproof. If noise is a problem, many customers pair it with earplugs for a calmer sleep environment.

Is it claustrophobic?
Most users say it feels calming rather than confining because it only covers the upper body and there are no zippers You can also tie back one or both front drapes when you want it more open and it will still block some light.

Is it safe for kids and teens?
zDen uses CPSC-compliant materials that are lead and phthalate-free, and it is designed as a sleep aid rather than a toy. For younger users, aged 5+, adult supervision is recommended.

Can I read inside without bothering someone else?
Yes. Many people use zDen as a personal sleep space in shared rooms. If you use a small book light or an e-reader, the den helps keep light contained so it is less likely to disturb others.

How do I set it up and fold it down?
zDen pops open in seconds. No assembly required. To fold it back into the travel case, follow the video and folding steps shown below. After you do it once or twice, it becomes quick and easy. However, if you still have issues, please reach out to us at info@myzden.com

Will it work if my room already has blackout curtains?
Many people still have “light leaks” even with blackout curtains, like gaps around the edges. zDen also blocks out the lights within your sleep space, such as electronics lights, hallway light, television, alarm clock, and more. zDen adds that an extra layer of darkness right where it matters most: around your head.

Does it get hot? How does airflow work?
Most people find it comfortable because only their upper body is covered. zDen has mesh windows and interior flap covers so you can adjust airflow. To maintain maximum darkness, open the flap that is furthest from light sources (ie. Windows, bedside clock, nightlight, etc.). Many customers use it year-round by adjusting their bedding. There is a loop on the back right edge for hanging a bladeless fan for extra interior breeze or white noise.

Does zDen have a bottom, or is it open underneath?
Yes, zDen has a quilted, padded bottom that sits directly on the bed. It adds comfort and stability and helps keep the sleep space feeling structured while you rest.

Is the fabric really soft and quiet?
Yes! Our fabric is crafted exclusively for zDen, offering the softness of your favorite bedsheets. It is also quiet, so as you move there is no crinkly noise to wake you up. The quilted bottom adds comfort and stability.

Can I travel with zDen?
Yes. zDen folds into an 18" circle and fits into the included travel case, making it easy to pack for trips, hotels, and visits with family.

Will it fit my pillow? What pillow works best?
zDen fits up to a queen-size pillow. Most customers use a standard or queen pillow while other use a wedge pillow. zDen is 24" high, so there is ample room between your face and the top of the zDen.

Can I use it if I sleep on my side?
Yes. Many side sleepers use zDen comfortably. Since your lower body stays outside, you can shift sides as needed. And our patented arched flexible frame design is made to move with you, so you can rest uninterrupted.

Can I use zDen on a couch or an air mattress?
Yes, you can. The quilted bottom helps zDen sit comfortably on different indoor surfaces. For best results, use it on a flat, stable area that gives the quilted bottom full contact, for stability, place your pillow inside, and adjust the drapes and windows to your comfort.

What gives zDen its structure?
zDen uses a flexible arched frame for shape, and the quilted bottom for stability where it sits on your bed or other flat surface. Your pillow goes inside for the same comfort that you would normally have on a bed and added stability.

Is it easy to get in and out quickly?
Yes, you can get in and out quickly because it only covers the upper body (not full-body or full-bed enclosure) there are no zippers, snaps or buttons. The front drapes can also be tied back when you want to watch TV unobstructed.

Is there a smell when I open it?
Our fabric does not have a scent, but some customers may notice a “new product” smell at first. If you do, let it air out in a well-ventilated indoor space before first use.
