These pillows have by far been the best pillows that we have used. We started out trying it when we got our new mattress and it has turned into purchasing multiple more for both my wife and I.
The stay nice and cool while also providing amazing support.
General pillow comments: firm but not too firm, however my wife thought it wasn’t firm enough. Supportive on your neck when laying on your side however I’m a stomach sleeper and I wouldn’t recommend using it while on your stomach. Smell dissipates after 24-48 hours. Pillow material is slippery and I noticed it comes out of some of our pillow cases easily. Pillow stays generally cool. The logo on the pillow is slightly raised and can be annoying to feel under my head. The logo is also dark and shows through pillow cases quite easily.
It is the only pillow our entire family sleeps with. We give them as a gifts. During my pregnancy it was hard to get comfortable but the pillow really helped especially with the acid reflux. Most pillows go flat but this pillow creates a normal curvature in the neck
