I have to say, after decades of buying all sorts of pillows, trying to work for me and my short neck, this is THE one. I bought the low profile ones and OMG it is just perfect for me. I'm finally getting a good nights sleep without fighting a pillow that is too firm or doubling a pillow that is too soft and thin. It's also not as heavy as other memory foam pillows I've tried. I hate a heavy pillow. Yet, it isn't so light weight that it gets pushed off the bed easily if you change positions a lot during the night.

The best Pillow ever!

I am a life long latex pillow user! The one i typically use is 150+. This pillow is better and less expensive . It has just enough firmness but still soft . I am a side sleeper and it supports my neck perfectly . I am going to buy three more!
