DONT WASTE YOUR MONEY!
Style: Original, Size: Standard/Queen
I ordered 4 pillows and paid almost $100 for them. They're absolutely pitiful! I could have bought better pillows at Walmart. They're soft and thin. Not at all what I was expecting.

Puffed out to be fluffiest pillows yet.
Style: Original, Size: Standard/Queen
When I received my two pillows I was concerned they wouldn't be as fluffy as advertised; they came rolled up and shoved in a small box. However, after some time sitting out they are even fluffier than imagined. Firmness is exactly what I wanted and even after my husband folds them, they bounce back to their previous shape.
