Doesn't last long
Size: King (Pack of 1), Size: King (Pack of 1)
I have only had this pillow for 8 month and it is flat and not comfortable anymore. I sent the company an email and they never responded. I do now recommend that you buy this pillow.

The pillows have a chemical smell
Size: King (Pack of 1)
I bought two Marlow pillows a while ago. They are great pillows. The two new Marlow pillows I just purchased have a chemical odor. The manufacture date is Sept. 2024. I have them airing out hoping the smell will dissipate , so far that has not happened.

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.
