Pillow received was 19 1/2 inches long, not 22 as stated in the description. It is VERY small. While it does stay cooler than your average pillow for longer, it will still warm up. Given the small width, you cannot "move to the other side" of the pillow for more coolness. Gel is only on one side, so you cannot flip the pillow over. Furthermore, if you add a zippered pillow cover under your pillow case, it is more difficult to enjoy the cool. This was a great idea, but fell very short, in my estimation. Returned it!
