Great Pillow!
Size: King (Pack of 1)
Excellent product. I have been searching for a pillow that wasn't too soft or too hard and supported my neck. I now wake up without a stiff neck and a headache. Wonderful!

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.
