Frequently Asked Questions
Our mattresses are made-to-order, so the product takes a little more time to get to you, as they’re not sitting in a warehouse collecting dust. The mattress, once compressed, will ship directly to your door. We are currently experiencing delays due to COVID-19, so it may take up to two weeks before we ship your mattress. You will be emailed a tracking number as soon as your order ships.
Contrary to what some might believe, the Comfort Channel is not conducive to numbness or tingling in your arm. When a body part β€œfalls asleep”, as the saying goes, it is due to lack of circulation, or not enough blood reaching the body part. When your arm starts to tingle or loses feeling it is caused by a position you are in that is cutting off this necessary circulation that supplies oxygen to the nerves that run between your neck and your arm. Nerves have their own blood supply, so pressure on a nerve cuts off that blood supply and the nerve becomes starved for oxygen and shuts down. This happens often on traditional flat mattresses as you are forced to overextend your shoulders and arms into positions in which they are not meant to rest, which can cut off this circulation. While side sleeping on a flat mattress you are forced to apply unavoidable pressure on these body parts which results in the discomfort and lack of circulation that can cause this numbness. The SONU Sleep System’s patented Comfort Channel design helps to greatly relieve these pressures on your arms, and with this relief comes improved circulation and reduced chances of numbness.

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.

So I actually own one of these. It's AMAZING. Yes it will take you a few weeks to get "used" to it... But that said, you will be AMAZED at how great your shoulders feel in the morning. Just unreal. Like sleep a full 8 hours without waking up type of sleep.
