TWIN XL

The Twin XL mattress is the least wide bed we make at 38 inches wide and 80 inches long. Its compact footprint makes it ideal for single sleepers, or in a set of two, for a split king setup.

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 a 'frozen shoulder' I’m dealing with, and with my new Sonu Cali King I’m able to sleep on my left side without any pain. It’s great! Highly recommend this new way to 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!

This comfort channel they made is next level. I never imagined that I would be able to put my arm in the mattress. Takes all the pressure off my shoulder, which I so so need. YES
