I'll never sleep another night without my trusty (slightly ridiculous) blackout tent
It looks like the Grim Reaper’s hood, but this personal sleep sanctuary is my secret to a better rest

TL;DR
- The zDen is a pop-up tent made from non-toxic fabric designed to block 99% of light.
- It is large enough for a queen-sized pillow and covers the user down to their ribcage.
- The tent features Velcro-closed flaps and mesh windows with covers for ventilation, plus CPAP pass-throughs.
- The author finds it improves sleep quality by facilitating back-sleeping and eliminating light disruption.
- It is also useful for travel, especially in locations with long daylight hours or inadequate light-blocking.
- The zDen's creator, Danielle Fujii, developed it for migraine relief, but it also helps shift workers and pet owners.
- Other recommended sleep aids include the Coop Original Adjustable Cut-Out Pillow, Mzoo Sleep mask, Loop Dream Ear Plugs, and Quince European Box Quilt.
