Simply The Best
Size: King (Pack of 1)
It appears there are more than 1,000 pillows advertised and available all over the Internet. The situation is a comedy routine. If you want a cooling pillow because you're a hot sleeper or if you want a plush pillow for back problems or a combination or neither, it doesn't matter. Be prepared to read 1,000 different advertisements until you start laughing out loud. This is what I did, but I wandered upon this Marlow Pillow system and then trusted the Amazon ratings. And boy am I happy, though a word of caution: if you want the cooling technology to really work you've got to pair this pillow with the Marlow pillow protector. Because Amazon didn't carry the pillow protector I bought it directly from Marlow. And this is the last pillow I'll ever get or need to get. Comfortable like a goose down pillow and yet cool to the touch and cool all night long. So I got lucky; have avoided having to buy multiple pillows; and now am enjoying the heck out of my Marlow King with the Marlow pillow protector. Lastly, this pillow is adjustable with a zipper and it works: you can make it softer or harder with a quick zip. The best pillow out there, by far!

Really good pillow!
Size: King (Pack of 1)
This is the first pillow that I have owned in the last 10 years in which I have not experienced any neck pain. It's the right density, comfort level, and is a high-quality item. I am a side and stomach sleeper. Try this pillow and I think you'll be happy.

Dream pillow
I’ve been using latex pillows for over 30 years, and I can’t find them in local stores anymore. I’ve been needing to replace my pillow and finally decided to try this one. There are so many options on Amazon that it’s overwhelming. But this standard low loft pillow ended up being PERFECT. It feels amazing and just like the pillows I’ve been using since childhood. It is soft but cradles my head and neck perfectly. For me, it’s like sleeping on a gentle cloud. Very happy with my purchase. (Yes, it does have a slight latex odor. That is normal due to the material. It’s not very strong and it doesn’t bother me).

Great latex pillow
Size: Queen (Mid Loft), Number of Items: 1
This review is for the biamktp queen pillow. Medium firmness. Finally a latex pillow worth keeping. After trying many other latex pillows I'm finally sleeping comfortably. This pillow is soft, yet firm enough to give your head support. I'm not having any neck or shoulder pain when I wake up. I'm sleep on my side about 95% of the time. 5% on my back. I've been sleeping with this pillow for about 10 days and still am happy with it. It was delivered on time, absolutely no odor and it has a removable cover. I highly recommend it.
