zDen

Transform your sleep with zDen, the original light-blocking luxury sleep den. Sleep doctor approved, CPSC compliant, and trusted by thousands. U.S. Int’l Reg. No.

Made with certified non-toxic fabric. Patents No. 12,305,414 & D1018753. DM/221128. Transform your sleep. Sleep better day and night. Block light with zDen for quality sleep, anytime of day. zDen's patent-pending design blocks more than 99% of light for higher quality sleep. While blackout curtains are generally effective for blocking outside light sources, zDen helps shield you from the lights outside and within your sleep space. Your cell phone, TV, digital clock, & bedside lamp are all light sources that you may not realize are negatively affecting your sleep quality. zDen also blocks out light from roommates who have different sleep and study schedules, plus night lights which make it safe for you to walk around, but adversely affect sleep. Plus, zDen is portable so you can get quality sleep when you travel. zDen — A better sleep solution
