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!

Too Soft for Him, Just Right for Me
Size: Queen Size: 27.6"L x 15.7"W soft, Color: White
My husband purchased this for himself but found it to be too soft for his preference. I decided to try it, and it worked well for me. While I agree it’s not as firm as either of us typically like, it still provided adequate support, and the shape retention held up nicely. Overall, it wasn’t a match for him, but it worked just fine for my needs.

Great for a side sleeper. Firm enough that it doesn’t collapse but soft and cool

Love this pillow!
Size: Queen Size: 27.6"L x 15.7"W soft, Color: White
I sleep on my side and this pillow is great! I also enjoy the cooling aspect. I forgot my pillow at a hotel and had another one ordered before I got home.
