Best Cool Sleep
“Immediately could tell the difference once I went to bed with the Luxury Mattress Encasement! So soft and cool, and it stayed securely on the edges of my mattress. There were no wrinkles after washing. I had never heard of Cosy before, but I will definitely be buying my bedding from them going forward after this purchase. Their prices are a win-win when you want a good rest.”

It Really Works, & It Zips!
“This Luxury Mattress Encasement is so soft and does not shift. I was skeptical at first, but it hugged my mattress tightly and didn’t move an inch! I couldn’t even tell it was on the bed. I also love that it’s waterproof and doesn’t make any noise, too. I feel protected with this cover, and I’m very pleased with this purchase!”

    Our Zippered Mattress Encasement is designed with a unique, double-layer membrane technology that absorbs liquids and shields your mattress.
