What Is A Negative Space Mattress? A Complete Guide

What Is A Negative Space Mattress? A Complete Guide

Restful sleep is one of the most crucial aspects of a healthy lifestyle. When you’re well-rested, you’ve got the energy you need to take on the day and feel your best physically and mentally. That all starts with the right mattress.

Finding the right mattress for your specific needs can be tricky, especially if you sleep on your side. Side sleepers often experience discomfort on typical mattresses, which don’t provide the necessary support for your neck, shoulders, and spine. That’s where the negative space in the SONU Sleep System mattress comes in.

If you’re wondering what a negative space mattress is, keep reading. We’ve got all the information you need in the guide below.

Where Typical Mattresses Fall Short

A standard mattress has a fairly straightforward design. While mattresses vary in thickness, softness, firmness, and other parameters, the overall layout is always the same. However, not everyone sleeps the same way.

The three primary sleeping positions are the side, back, and stomach. While some people prefer to sleep on their backs or bellies, side sleeping is the most popular position among adults. However, a typical mattress is the least accommodating to side sleepers. Here’s why.

Normal Mattresses Have No Space for Your Arms

If you sleep on your side, you know how frustrating it can be when you can’t get your arms comfortable.

There are only a few options for positioning your arms when sleeping on your side on a typical mattress. You can either stretch an arm out in front of you, curl it over your chest, or try sleeping with it flush with your hip. 

However, all of these positions can be uncomfortable. You might even find that your weight-bearing arm falls asleep or goes numb in the middle of the night, disrupting your sleep and making it even harder to get comfortable.

How the Negative Space Mattress Solved the Arm Problem

In contrast to the typical mattress design, SONU’s negative space mattress comes equipped with the patented Comfort Channel for your arms and shoulders. That means you won’t have to shift and shuffle around all night looking for the most comfortable position. 

The materials surrounding the Comfort Channel are smooth and soft, which allows your arm and shoulder to easily slide in without any resistance.

Normal Mattresses Aren’t Adjustable

It’s tough to get comfortable on a standard mattress, especially when you can’t adjust where your head and neck rest relative to the rest of your body. 

A negative space mattress eliminates the discomfort of typical mattresses by introducing adjustable layers beneath your head and neck. These layers are the patented Support Pillows of the SONU Sleep System.

SONU’s Top Pillows, which are designed to pair with the Comfort Channel, make it easy to get comfortable and change how you sleep whenever necessary. The Support Pillows, which are located within the Comfort Channel and below your Top Pillow, allow your arms to rest where they're meant to; beside your torso without the weight of your torso putting pressure on them, causing poor circulation and discomfort. By eliminating these problems, the SONU system allows you to finally sleep like never before.

Normal Mattresses Offer Limited Range of Motion

If you’re a side sleeper, you need a supportive balance between your neck, shoulders, and spine to stay comfortable. 

On a standard mattress, you have extremely limited range of motion due to it being flat, without any space that arms truly need, as well as a non-adjustable design.

On the other hand, the negative space mattress offers full range of motion below the surface, enabling better breathing and circulation, no more numbness in  arms and hands, prevention of nerve damage, improved alignment of spine, resulting in an overall elevation of comfort that your body has always needed.

The Negative Space Mattress Is Every Side Sleeper’s Dream Come True

The SONU Sleep System was designed with side sleepers in mind, and it shows. If you sleep on your side and are tired of your neck hurting every time you wake up in the morning, it’s time to make the switch to a negative space mattress. You’ll feel the difference literally overnight.

Here’s what makes the SONU Sleep System perfect for side sleepers. 

The Comfort Channel

The SONU Sleep System features a unique component that provides side sleepers with the perfect place for their arms. 

The Comfort Channel is a patented feature of the negative space mattress that provides side sleepers with full range of motion for their shoulders and arms while resting. That means deep, rejuvenating sleep throughout the night and fewer aches and pains.

The negative space mattress’s Comfort Channel is directly beneath your pillow, right where you’d typically rest your arm. That means you can wave goodbye to uncomfortable nights of tossing and turning while trying to find a way to get comfortable on your side. 

In addition, the Comfort Channel provides your neck and head with better support as well. The uniquely engineered design keeps your head level and reduces the amount of weight and pressure on your arms and shoulders. That’s fantastic news for anyone who wakes up with aches. 

The Support Pillows

The negative space mattress also features the patented Support Pillow system, which provides your head and neck with the ultimate level of comfort and relaxation. Your SONU comes equipped with these specifically designed layers to give you ergonomic support than is impossible with all other mattress. 

These Support Pillows are designed to sit underneath your current top pillow or a SONU Top Pillow Deluxe.

We highly recommend pairing the negative space mattress's unique Support Pillow System with the SONU Top Pillow Deluxe. It’s the perfect combination of malleability, support and cooling thanks to high-quality, ultra-breathable material that also promote better airflow throughout the night. 

Sink-In Support

One of the key features that sets the SONU negative space mattress apart is its ability to keep your spine aligned. This constant alignment reduces the amount of pressure and tension on your back, leaving you feeling more refreshed and rejuvenated when you wake up. 

Upper Torso Relief

If you’re sleeping on your side on a flat mattress every night, your arms, shoulders, neck and chest are certainly suffering. Many side sleepers complain of waking up with shoulder pain after sleeping on either their left or right sides. This pain is the result of awkward arm placement, because there's simply no place to put it on a flat mattress.

The negative space mattress is exactly what you need if you’re looking for the most comfortable side sleeping experience possible. Waking up with numb arms and hands from poor circulation throughout the night, or tight shoulders and back in the morning is no fun. Finally there's a solution to all of this.

The SONU mattress's revolutionary system cradles your arms, shoulders, neck and chest to provide your body with the relief it needs every night. 

Can a Negative Space Mattress Help You Manage Pain?

If you deal with frequent bouts of discomfort or an injury in your arms, shoulders, neck, back or chest, the negative space mattress is what you need to actually get a restful night of sleep. 

Pain in these areas is exacerbated by the way you sleep, and the mattress you sleep on. If you’re tired of waking up feeling achy, the SONU Sleep System is exactly what you need to help you sleep comfortably and wake up pain-free.

Why You Wake Up With Aches and Pains

If you wake up with aches and pains after sleeping on a standard mattress, it might be because the design of your mattress doesn’t fit with the way you sleep. That means you’ll wake up throughout the night and feel achy and groggy unless you swap out your mattress for something that will truly give your body relief. 

With the SONU Sleep System, you get the support where your body requires it, and much needed space where it doesn't. Instead of dealing with constant aches and pains caused by your flat mattress, prepare yourself for relief and the best sleep of your life.

How Pain-Free Sleep Can Change Your Life

Dealing with pain caused by your mattress and sleeping position can dramatically affect your day-to-day life. If you’re in constant pain in your neck, shoulders, and back, you’ll be amazed by how much getting the relief you need can change everything about how you live.

When your mattress actually supports your body instead of making you feel achy and uncomfortable, you’re free to live uninhibited again.

When was the last time you woke up feeling comfortable, refreshed, and energized? If you can’t remember, it’s time to upgrade your mattress right away. 

Choose SONU For Your Sleep Needs

If you’re looking for a way to transform your sleep, the innovative negative space mattress is for you. No other mattress even comes close to the level of comfort that you’ll get side sleeping on the SONU Sleep System. 

While a normal mattress doesn’t accommodate side sleepers, the negative space mattress is made to optimize the side sleeping experience. With its patented Comfort Channel and Support Pillows system, and countless other  benefits, the SONU Sleep System mattress has everything you’ll ever need for restful and truly rejuvenating sleep.

It is finally time to sleep like never before... with SONU.

Game changer

I tried many remedies but none solved my problem until I discovered the Sonu mattress with the cut out arm channels. This has become a game changer. No more shoulder pain, no more dead arms, and the most comfortable sleep I have had in years.

Finally sleeping again!

As someone with frozen shoulder in one arm and having had surgery on the other due to frozen shoulder, sleep was fleeting. I hadn't slept well for about 2 yrs until I got this mattress. It has been life changing for me!

Finally!

For 40 years I have wanted a bed with "a hole in it for my arm". Better than a hole is this design. No more pain or numbness plus it is gentler on my hip bone and better for my lower back.

Fantastic!

I had just about given up on thoughts of sleeping through the night ever again. I would wake up 30 to 40 times a night to adjust myself. I can't begin to explain what it feels like to sleep through an entire night.

Relief from shoulder and neck pain

I'd wake up multiple times a night because of my arm falling asleep or pressure on my hips, and then wake up with terrible neck pain. I wake much less frequently in the night, and I have no pain in the mornings!

Life changing

After two rotator cuff surgeries over the last 5 years I haven't been able to get a good night sleep. I was nervous about the big investment, but I'm glad I did and would recommend to anyone with shoulder problems.
