Bang for Buck

We were looking for a mattress topper that provided firmness and coolness to our bed. This topper did just that. After reading all of the reviews, I agree that the quality for the price paid off. Typically I toss and turn through the night looking for a cool comfortable position to lay in but since adding this mattress topper to the bed I have slept much better. Only time will tell if this product really delivers what it says it would.

Blown away! Purchased 2 more the same day!

I I highly recommend this product. It made my bed feel unbelievable. I ordered two more immediately for my brother and his wife and for their second bedroom in their house.. whoever purchases this mattress, memory foam cover will be completely satisfied and blown away and wish you had purchased it a lot sooner!
