TWIN XL

We enjoyed our first SONU mattress so much that we replaced our other bedrooms with SONU's as well. These mattresses are amazing!!!

AMAZING
β˜…β˜…β˜…β˜…β˜…

So I actually own one of these. It's AMAZING. Yes it will take you a few weeks to get "used" to it, because at first the sensation is not unlike feeling as if your about to fall off the bed. 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.
