Review on Revel 4-Inch Hybrid Mattress Topper with Cool Gel Memory Foam and Lofted Fiber Fill Cover, Queen Size - Made in The USA with 10-Year Warranty, Amazon Exclusive by Clay Elmer

Ordered a 4 inch hybrid. I think I should have paid more attention to the photos. The mattress I received swelled up to 2.25 inches after taking it out of the box. It's just some kind of foam, which I wouldn't call a cool gel. I was expecting there would be at least 2 layers of foam, one regular memory foam and the other cool gel, for a total of 4 inches. A mattress cover was also supplied, but the cover does not belong on a 4 inch mattress in my opinion. I'm not sure how to return the item as it swells up after unpacking and trying to wrap it up and return it is not an easy task. I can just make it a habitat for humanity.
