With May upon us, it's only a matter of time before the Memorial Day mattress sales begin. But if you can't wait until then, Viscosoft is offering mattress toppers at a huge discount.

For a limited time, the Viscosoft Active Cooling Copper Topper is on sale for $199.77. That's $133 off and one of the best mattress topper discounts we've seen.

Viscosoft makes one of the best mattress toppers you can buy. In fact, the Active Cooling Copper Topper is featured in our Mattress Topper Guide. The variety of materials keep you cool at night, especially if you sleep warm.

The mattress topper comes with a removable and washable fabric cover that allows moisture to escape. Meanwhile, the interior has 2 inches of antimicrobial copper-infused foam that helps regulate body temperature by drawing heat away from the body. Another 2 inches of support foam relieves pain from pressure points.
