Best pillow ever
Style: Standard – Low
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!
Size: Queen (Mid Loft), Number of Items: 1
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!

Make sure you're not allergic to latex
Size: Queen (Mid Loft), Number of Items: 1
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.
