Know before you buy
The difference is purely in the profile height and overall depth of the mattress. Both options provide the same quality of support and comfort, so the choice depends on your preference for a lower-profile bed or a taller, more substantial look.
The Firm option is generally better for back or stomach sleepers who need more structural support to keep their spine aligned. The Soft option offers more contouring and pressure relief, which is typically preferred by side sleepers.
This certification ensures that every component of the mattress has been tested for harmful substances. It guarantees that the materials are safe for human health and meet strict international safety standards.
Because the mattress is vacuum-sealed for shipping, it will begin to expand as soon as the packaging is removed. While it often reaches its full shape quickly, we recommend allowing it to settle for a few hours before use.
No, the Sonno M Mattress features an all-white, non-removable cover. We recommend using a high-quality mattress protector to keep the surface clean and extend the life of your mattress.
The 100-night trial allows you to test the mattress in your own home to ensure it meets your comfort needs. If you find it isn't the right fit within that window, you can initiate a return.
