This pillow is so soft and bouncy! After using it for a couple of nights, I felt that it wasn't high enough for me, as I'm a side sleeper. So I started using it with another thin pillow underneath it. That worked fine and I was happy with it until I started developing itchy skin on my neck, scalp and ears! Now, to be fair, this isn't the pillow's fault! I just didn't know I was allergic to latex! I unfortunately had to return it.

My husband bought me this pillow - I loved it so much I bought a second one! It is so comfortable and keeps its shape. I would buy again!

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.

The Best

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