What a great pillow, finally one that fits inside my oversized king bed shams perfectly, filled it out fully, fluffy but full, has good support, not a soft or a hard pillow just really full all the way to the corners, made very well good quality, but this would actually be a good bed pillow but for me its for my shams & I couldn't be more pleased, highly recommend.

Revised review

Size: 20 Inch by 26 Inch

I have ordered many of these pillows and loved them! Nice and squishy but didn’t flatten like down pillows. I needed a bunch for Airbnb but they are very pricey. Was reading the reviews and several said that the pillows had changed. I thought, how much could they have changed? So I went ahead with purchase. I felt like I may as well have gone to Walmart and bought a cheap foam pillow. Update: finally tried the pillow myself. Although there is a definite difference, it is very soft and fluffy. Changed my rating from 2 to 4 stars.
