Terrible product. Sleeps extremely hot and traps air underneath it so the sheets bubble up. It's like sleeping on plastic. I also received terrible service from Wayfair. This product was recommended to me by Wayfair to accompany a mattress I purchased and it was the wrong size. I was denied the opportunity to exchange the product for the correct height size (knowing that you've got a double does not guarantee this will fit properly), even though the recommendation error was Wayfair's. I will never buy from Wayfair again.
