To design our Sonno Mattress, we worked with a family-run Italian company that’s been studying the science of sleep for 55 years. In that time, its design team has perfected their ability to transform the highest-quality Italian materials into the highest-quality sleep experience. Every component of a Sonno has a benefit – there’s no meaningless fluff – and every mattress is certified STANDARD 100 by OEKO-TEX, which means you can be certain that every part of it has been tested for harmful substances. Even the way Sonno ships is revolutionary, thanks to an innovative “bed in a box” method that brings end-user and environmental benefits to the entire transportation process. It ships rolled in a compact tube for easy handling and quickly expands to full thickness. Backed by a 100-Night Sleep Trial and a 10-year limited warranty.
