Amazing experience
While furniture shopping with my husband, I laid down on this King Kool Smart life mattress and was instantly in love. It sensed by body type, height and weight and created the perfect supportive comfort for me. I adjusted the degree of firmness I like, which is 3 on their scale, and relaxed instantly. The gentle wave motion was blissful. My husband joined me and was able to adjust his side how he likes and he found the ideal position when he raised the head of his side of the bed. We were both incredibly comfortable and it was all we could do to not fall asleep in the middle of the store! There was none of the usual pressure on my shoulder and hip, as I am a side sleeper. Plus, with the app and controls, it can keep track of our sleep and monitor our comfort. I can’t wait to save up some money to buy one of these fabulous mattresses.
Love our SmartLife!
My husband and I love our SmartLife mattress! He likes a softer feel, and I like a firmer feel - with SmartLife, we both get exactly what we want. And I love relaxation mode, I turn it on every night to help relax and fall asleep. Our best mattress ever!
Mr

King Koil
I had a Sleep Number bed for 10 years and thought I was ready to replace…during Covid they were unavailable and the King Koil was recommended to me by David Dean, my designer at Mathis Brothers. This mattress surpasses any other mattress I have had. Love the app to see my sleep results each morning. The massages and relaxation mode are useful to prepare for sleep. A+++
