Comfortaire U11™ Split Top King

Every so often you come across a bed that seems as though it was made just for your body. That’s what many experience when they lie down on the U11 mattress by Comfortaire. Part of the Ultimate series collection, the U11 offers personalized adjustability and ultra-comfort for a superior night of relaxing sleep.

The U11 mattress gives you the unique ability to control your side of the bed only. Using the power of air and the Q10 air pump with 100 comfort levels, you can adjust your side of the bed to your ideal spinal position and level of comfort.

The split-top mattress comes with a soft bamboo-based rayon cover that wicks moisture and keeps you cool throughout the night. The ultra-plush green tea scented EvellaFoam comfort layer hugs your body and drifts you off to sleep in true style.
