Being oversized at 28"x28", these definitely fill out my euro pillow shams much better than the other 26"x26" euro pillows that I bought previously. These are soft but not too soft, so they actually do provide some back support, which is important while sitting up in bed for reading. I knocked 1 star off the rating because these euro pillows are not machine washable but rather spot clean only. However, that's not too big of a deal since I use allergy pillow protectors. For the price point, these are good value.
