ViscoSoft 4 Inch Active Cooling Memory Foam Mattress Topper Black Twin - Made in USA Select Copper-Infused Mattress Pad

Outstanding quality on the cover. I unrolled the topper and it expanded quickly. The cover was folded up inside. When I touched the cover it was cool even though I just brought in the box and it was sitting in the sun on my porch. I bought to use as a bed for 75 pound dog. He loves it. He stays asleep longer because he isn't overheating. He is having surgery and I wanted him to rest comfortably. Normally he gets up 3 to 5 times because his bed is too hot. I got the twin and put it on the floor. It is supportive enough for my dog to use alone. His weight is distributed.
