Very disappointed after reading decent reviews. The pillow itself doesn't have a a well defined shape and is VERY SOFT AND MARSHMALLOW-ish. The pillow cover is cotton knit and isn't thin but doesn't help the pillow to keep its shape. It's approximately 5.5 to 6 inches high.

So comfortable. I love it. It’s firm and holds its shape, yet it cradles your head, and its soft. It’s wonderful.

Memory foam could never
Size: Queen (Mid Loft), Number of Items: 1
Wonderfully firm, yet responsive and lightweight. Like a marshmallow for your head and neck. I'm a side sleeper, but this could be great for anyone needing firm but still very soft and comfortable support. Memory foam has nothing on actual latex.
