The canopy offers good shielding against Microwave radiation such as cell phone towers, Wi-Fi, and cordless phones. Side slits provide easy in/out access and multiple ceiling attachments help create excellent inside volume and a sense of airiness. The fabric incorporates super thin silver threads which reflect RF radiation, and could help you get the refreshing sleep you need. The Bed Canopy is Easy to install, washable, and no need for grounding. Great for home use or travel.
