Good product.
Color: Gray, Size: 18"x24"
I live in Michigan so we have cool nights. We have hot days. Last night I went to pick up my new cooling mat to put it up for the evening and was totally blown away at how cool it was to the touch. For the price, the quality is outstanding. I will be purchasing more in the future once I know that my cats will use it. We haven't got that far yet, but once they do I will try to include pictures of them using it. I hope this helps someone as I am pretty picky about what product I buy. I was thoroughly impressed. The back side, or the warmer side is very soft and perfect for winter time use. It was an absolute genius idea to make one that is universal.

Max loves it!
Color: Gray, Size: 24"x36"
Phoenix got hotter sooner this year, and even with a short haircut, my baby kept trying to find a cooler spot. I had my doubts about whether this bed would actually keep him cooler, and Max was initially suspicious (especially after he saw the cat picture on the label). It only took one hot afternoon to sell him on this cool, comfortable lounge spot. It does feel cooler; it's a lot more comfortable than the hard tile floor and he is out of the way when on it. Good buy at a good price.

GREAT QUALITY CAT BED
Color: Gray, Size: 18"x24", Color: Gray, Size: 18"x24"
We love this self-warming and cooling cat bed because it's super soft, and the cooling side really works well! I can feel with my hand how cool it is by just touching it. I plan to put this outside in my cat's outdoor house; it will really help keep him warm in the winter and cooler in the summertime. It was super easy to throw in the wash on delicates, and I hung it up to dry. It's the perfect size, too; it should fit in his cat house perfectly and is big enough for him.

This mat works so well for my kitty!
Color: Gray, Size: 18"x24"
This pet bed is such a smart find! Someone had the smart idea to make a bed that stays cool in the Summer and warm in the Winter! The material on the Winter side is soft, snuggly plush with a foil layer to hold in the heat. Flip the mat over and it’s the perfect cooling mat for Summer, with a cooling ice silk fabric to keep cool. The mat is the perfect size for a small dog or a cat. Spot cleaning is recommended as the preferred way to clean but the listing says that it can be washed using the gentle cycle. It needs to be air dried however. My cat wasn’t impressed to begin with, but once she got a little playtime with her favorite toy and some catnip, she settled right in. This is a good mat to fit right into her crate for traveling.
