SLEEP ZONE Cooling Twin Mattress Topper for Single Bed, Premium Zoned Quilted Mattress Pad, Fitted Mattress Protector Cover, Machine Wash Durable, Deep Pocket 8-21 inch, Silver Grey, Twin

I added a 4" memory foam topper to my mattress. My topper slid everywhere with regular sheets. I'm using this as a bottom sheet & it works great. It's soft & comfortable & my topper doesn't slide anymore. It's well made & I'm very happy with it.

Kind of flat but notice it underneath. Just like you have many layers of sheets. It is basically thin layers of plastic with billions of tiny holes. When it is made for cloth, the air gets through the fabric easy and dries it quickly when you feel cool. But when you lay on it with your weight for some time, the heat builds up because new air can't get in and the heat can't escape. We don't move that much during sleep. I didn't feel it cooler than usual but hotter. But it is the best mattress protector I have ever had if you don't have a problem with the heat during summer.

It is the most comfortable, soft, yet supportive. Looks beautiful, fits beautifully. Nice tight and tucked fit. Love it.

It did not make my back pain any better. I should have bought a foam topper instead. It is not very thick and did not make a difference on my bed. I would send it back but the cost to do that would be high. Would not recommend it.

I don't use this anymore
