Review: Nice big euro pillow with good fill. - Looks great and smooth cover. Bigger than I expected, looks like it will have excellent support as a pillow headboard for my college bound daughter. I am very happy with this pillow. And made in the USA!
Review: Perfect for a King Bed - These 20x36 pillows fit perfectly on my King bed. I purchased two of them. The sham covers (that came with the bedspread) fit well also. I like the fullness of the pillows and the quality of the pillow itself. I use these pillows as decorative use...not for sleeping.
