Any thoughts on King Koil's Intimate mattresses?

Hello, thank you for any thoughts or suggestions in advance. I went to a SitnSleep store to try several mattresses in person, and am torn between a Tempurpedic Pro Adapt hybrid mattress and a King Koil Intimate mattress. I originally thought I would get a tempurpedic mattress because my folks swear by them, but the salesman swore that King Koil Intimate mattresses were better. I liked both, although they of course felt quite different. But they both felt very comfortable. I had never heard of King Koil until today, so wanted to get any advice or insights from those who are familiar with or preferably owned one.
