Low firm/supportive
It was good, however It wasn’t firm enough. It’s advertised as supportive so I guess low firm is where it sits in the chart

Perfect pillow
Size: Queen Size(2 Pack)
It’s a beautiful soft Material, way better than any pillow I’ve ever owned. It’s cool to the touch and remains fluffy and durable. I’ve had it over a month and still love it just as much as day one! The neck support is also very much appreciated! The size is perfect for my pillow cases. All in all a durable, soft Material, comfort pillow! Will buy again!
