LET'S GET STARTED

Time To Sleep Like Never Before
Congrats on your SONU Sleep System mattress purchase! You're on the road to sleeping more comfortably than ever before. Follow the steps below to properly set up and enjoy your new mattress - and when you're done, head over to the Best Practices page to get the most out of your SONU!
1
Unbox your SONU Sleep System, place rolled up mattress where you will sleep, then carefully remove the outer plastic wrapping.
Note: Cut the plastic only with the safe cutting tool provided with your SONU, not scissors or a knife, to avoid accidentally damaging any mattress materials.

2
Allow time for the mattress to unfold and expand fully, enabling all materials to take shape and provide full support.
Note: Expansion can take up to 48 hours, but in most cases a few hours will suffice.

3
Remove the SONU Support Pillows from the Comfort Channel, then move mattress into final place without grasping the Channel walls.
IMPORTANT: Always remove all pillows before moving the mattress. When moving it, lift only the main body area of the mattress to avoid damaging the Channel area.

4
Position the head of the mattress flush against a wall or headboard so that the upper wall of the Comfort Channel is firmly supported.
IMPORTANT: Do not sleep on the mattress unless its headboard area is fully up against a solid supporting surface. If the Comfort Channel isn’t properly supported in this fashion, damage to the mattress and discomfort while sleeping may occur.

5
Unpack the SONU Fitted Sheet provided with your mattress, align the Comfort Channels and fit it over your mattress.
Note: After positioning the SONU fitted sheet, ensure the bottom of the Comfort Channel is completely flat by pulling slack into the Channel and pushing the corners into place.

6
Place the SONU Support Pillows back into the Comfort Channel, on top of the SONU Fitted Sheet.
Note: Stack the Support Pillows in sets of two, just as they arrived prior to Step 3.

IMPORTANT: 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.

7
Place your favorite pillows for sleeping on top of the SONU Support Pillows. It is now time to immerse yourself in comfort like never before...
Note: Hug your pillow at an angle on top of the Support Pillows to bridge the Channel and support your head and upper torso, while your shoulders and arms enjoy extra space for maximum comfort and pressure relief that can only be achieved with a SONU.

Tips: Review more sleeping position tips and best practices on the Best Practices page.

WARNING: 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.

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 “falls 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.
