β€œSo 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.”

β€œi 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.”

β€œI’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!”

β€œ...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.”

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.
