Love it
Set name: UltraCool Pillow, King - Soft/Medium Firmness, Item length width: 40.0 Inches
I really like this pillow!! It’s a nice medium fluff. I do think it feels cooler. And, when you flip to the “cool side of the pillow” it’s realllly chilly. It’s very long - it sticks out of my king size pillowcase a little bit - but not enough to be bothered by it.

Worth the investment
Size: Standard (Pack of 1), Size: Standard (Pack of 1)
I’ve owned several. I toss them about every 5 years because well I haven’t found a way to wash it and not ruin it. I used to buy it at bed bath & beyond before they closed. And it was the same price there. It’s not memory foam. It’s latex. So if you are allergic- buyer beware. But it has a nice little bouncy- ness to it. Which I love. Cradles my head & neck. It has a zippered cover on it you can remove & wash. This one seems to have a thin, protective permanent cover thing on it. I assume so you potentially can wash the pillow. May attempt that in a few months.

Unreliable product be careful
Size: King (Pack of 1), Size: King (Pack of 1)
I bought this pillow and loved it. King size and firm. I bought another one and it is less firm and smaller in length (as seen here) and not at all to the quality onto first one. I’d be careful and check these if buying. Very disappointing experience

A little misleading
Size: King (Pack of 1)
Overall, it is comfortable. However, I ordered a king sized which is 36" long, but this pillow is only 33". That's somewhere between a queen and kind size. Second, it is not a medium firm. It is more toward soft and lets the head drift down close to the mattress level Over time, you may have neck problems. Time will tell. Update: It is great! My neck feels better and I sleep better. There is still a little odor, but it's not a problem. I recommend this pillow.
