I like my Sujo FlexCool pillow
Size: Queen
It cools nicely and it is possible to add or remove fill to optimize preferred comfort. Quality made and very comfortable for me after I added some of the fill provided with the pillow.

This was not for me
Size: King
Hmm… I didn’t hate this pillow but I was not blown away either.
I’ve been using Sleep Number pillow, and since the price range was similar, I thought this might be a great alternative, especially when it’s hot. Even though I was able to adjust the filling, I couldn’t find the right shape/density. And I found that this pillow felt hotter when I was sleeping.
After trying it for a few weeks, I went back to my Sleep Number pillow. The quality was fine. But I guess everyone is different, just like some people prefer a softer mattress and others don't.

Best pillow ever.
Size: King
How much did I like this pillow? My wife and I both loved it so much that we purchased another one. I think that says it all! The pillow arrives in a large box (king size pillow). It does NOT arrive all flattened and squished in a vacuum bag like some others do. I did place it on my back porch to air out for a while, just because that's what I do with any new bedding. I did not have any issue with scent or odors from either of my pillows. Its clearly well constructed with high quality materials. It comes with a smaller bag of extra stuffing if you want a slightly firmer pillow. We have not used any of the extra stuffing... we think the pillows are perfect as is! When I ordered the first pillow, I thought the price was a bit on the high side. After using it, I had no hesitation purchasing a second. This pillow is well worth the price. If anything, I feel this pillow is a great value at its price. Its not too hard, not too soft. Its the goldilocks pillow! I give this pillow my highest possible recommendation. Its simply a great pillow.

Excellent pillow, firm but more flexible than others of its type
Size: Queen Size: 27.6"L x 15.7"W soft, Color: White
I previously bought a similar pair of pillows from Sleep Innovations, but they are now either out of stock or unavailable. This new brand is a bit softer and more comfortable than the original pair. It's good for sleeping on my side or my back. The pillow cradles and supports the head and neck in a more contoured way than some harder pillows. The price is reasonable. The only difference from Sleep Innovations is that this pillow does not have a zip cover. So there is no way to wash the exterior. I suppose that one could buy a zip cover for it at extra cost.

Side sleepers rejoice!
Size: Queen Size: 27.6"L x 15.7"W soft, Color: White
I have spent hundreds of dollars on pillows. I am primarily a side sleeper and every few years I find myself waking up with a "crick" in my neck accompanied by pain and tension. I have had this pillow for only two nights and I am leaving a positive review. It is firmer than one would expect based on first appearance and the "press" test. The surface stays cool and I can sleep any which way and I am still comfortable. Definitely recommend!
