Sonno MGV (aka “the relationship saver”) offers the versatility (that’s the V) of two individualized mattress halves inside its removable cover. Each half of this memory foam plus gel aerated foam (thus, the M and G) mattress has a firm side and a soft side for customizable comfort in a shared bed. 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.
