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.

i have suffered from shoulder pain while sleeping for several years, i had just about given up... then i saw this bed and decided one last try. i can't begin to explain what it feels like to sleep through an entire night... for the first time in 20 years the first weekend i had it. I'm so impressed with this bed... because what they are making is making a difference in people's lives.

I’m a side sleeper and I used to wake up with a dead feeling arm from lying on it all night. Finally a mattress with a pocket for my arm. I tried all the pillows and even very expensive mattresses in the past, but nothing cured my circulation problems until I got the sonu sleep mattress. I love it!

...Sonu mattresses are in a league all by themselves. This is the most comfortable bed I have ever slept on. I have no more shoulder pain and numbness. I can now sleep through the night and not wake up in pain. If anyone is even thinking about getting a Sonu sleep system don’t think anymore. Pull that trigger. I 100% gaurentee you will not be disappointed.

Frequently Asked Questions
The SONU Sheets are made from top quality 100% long staple cotton with 300 thread count for a smooth, cooling, breathable and luxurious feel to the touch.

Please note that contrary to popular belief, thread count does not necessarily equate to quality and smoothness, and that a thread count of 300 for high-end long staple cotton is top quality. Rest assured, we have selected the best materials to make sure these beautiful sheets perfectly compliment and complete the unique SONU sleeping experience.
The short answer is no! Contrary to common belief, higher thread count does not equal higher quality sheets. A better-quality fiber with a lower thread count will feel softer and stand up to washing better than a lower-quality fiber with a higher thread count. The thread count metric has been hyped as a type of gimmick by manufacturers to be able to sell low quality products for higher prices.

We’ve been trained to associate high count numbers with luxury - after all, we need some way to measure quality. But if you run this logic by any textile expert, you’ll be met with adverse information, as this assumption is incorrect. As linen expert Julian Tomchin told The New York Times, “once you get beyond 400 threads per square inch, be suspicious.” 1

By definition, thread count is simple - it's the number of threads woven into one square inch of fabric, by adding the verticals (called the “warp”) to the horizontals (the “filling”). But in reality, some manufacturers aren’t that straightforward. Think about it - only so many pieces of thread can fit into this set amount of space. It turns out that this means the number for a good thread count is between 300 and 400, depending on breathability and other performance goals. That means if you see sheet sets touting 600, 800 or 1000 thread count, the manufacturer has employed a deceivingly creative method to reach that number in a ploy to be able to raise the price!

There are many factors that go into what produces a quality sheet product, and thread count is only a small portion of the equation. Fabric content, fiber quality and finish are the big ones. Here at SONU, we’re proud to bring you top quality materials by paying close attention to the factors that actually matter when it comes to our custom sheets. After thorough testing of sheet materials in conjunction with our SONU Sleep System mattress, we’ve determined the best performance with our 300 thread count long staple cotton. Any higher thread count would diminish our ideal breathability and performance goals.

We’ve found the sweet spot with our top quality 100% cotton fabric for its heat wicking, breathability, durability and high level of softness - available in three colors to suit different decors and personal preferences. Please visit the SONU Sheets page for more details.

The SONU Comfort Insert fills in one side of the Comfort Channel, making the SONU Sleep System more akin to a flat mattress, but still with give for your shoulders. This versatility can be helpful for many scenarios including couples who sleep differently from one another (e.g. a side sleeper and a back sleeper) and for those who simply prefer less space in the Comfort Channel.
