This is probably one of the best pillows I have ever owned. I haven’t bought a new pillow in almost 10 years. I don’t get a good chance to actually look at pillows, let alone sleep, so this was a very good buy for me. It’s actually cold unlike other cooling pillows I’ve been given, it’s soft, large, and the support it gives for my neck is a lot better than my previous pillow. It’s also flat enough where I don’t have to constantly adjust it so I’m not waking up in the morning having to adjust it from breaking my neck.

Great pillow for side-sleepers, to keep things lined up.

Color: Black, Size: With Cover

I didn't actually expect this to be that useful, but it has improved my mornings a lot. Since I sleep on my side, often times I my knees would be uncomfortable when trying to go to sleep, or my neck would be sore getting up. This pillow gives me a bit of padding, and helps keep my hips and shoulders lined up. Simple solution, but works great.

Works perfect

Color: Grey

As someone going through perimenopause sleeping next to a hot sleeper, this has been life saver! Stays cool and some how keeps me cool and comfortable all night.
