I am reviewing the Beautyrest Black® Hybrid LX-Class - Medium, Queen.  This mattress was by far the best mattress I’ve ever had. 

It’s very smooth and the firmness of the mattress is just right! My back tends to hurt after having three kids but this mattress does it’s job! 

I loved the Beautyrest Black® Hybrid LX because of its cooling technology. I didn’t sweat once. It was also pretty big; big enough to fit myself, husband, and all three kids!
