I had a good pillow from tempur-pedic for 10 years, and it was time to buy a new one. Not only these pillows are long-ladting, but also very comfortable. I bought the same pillow as I had before with the cooling effect. I love it! You can always expect great quality and durability products from Tempur-pedic. Ps. My T-p mattress is 10 yrs old, and still no signs of aging.
