Absolutely fantastic! The cooling is as advertised. I wake up well rested and ready for my day.
This is my fourth Tempur-pedic mattress. This has the best performance of all the mattresses. The heat removal from the body allows the body temperature to remain comfortable; through the sleep.
I had an older TP bed that ran a little hot. This bed dominates in this department. It's a noticeable difference as this bed runs so much cooler.
This is our second Tempur-pedic mattress. We tried them all, and admittedly splurged a bit on the high end, but it seemed the most comfortable for a back sleeper and a side sleeper to share. It was, it is, and it feels like it will be. Firm enough, but not too firm. Very comfortable. Just right. The cool surface felt cool in the store, feels cool when you lay down, and stays cool and comfortable all night. I'm not sure that any bed is worth the price of this one, but we're happy we "spent" the extra mile.
Good night sleep
