LET'S GET STARTED
Do not put pillowcases on the Support Pillows, as they already have their own covers with hidden zippers for easy removal, washing and customizing of the foam layers within if needed.

The SONU Sleep System is not for children 12 years of age or younger. Do not allow children to play or sleep on the mattress as it is designed for adults only.
Some may look at the SONU design and believe that because your arms are below the rest of your body, you may have an increased risk of circulation issues or numbness. This is a common misconception, but is not the case - here’s why. Your arms are naturally below your heart when you are upright, walking or sitting, throughout the day. Your arms never tingle in this position because they are receiving the correct amount of circulation. The Comfort Channel enables your arms to also rest below your heart, as if you were upright, resulting in your arms receiving the correct amount of circulation – which actually reduces the chances of circulation issues or numbness, compared to flat mattresses. We have designed the Comfort Channel system with all of this in mind. You will be impressed at the elevated level of comfort and truly deep sleep you will enjoy on your SONU, enabled in part by the improvement in circulation your body will experience.
