Something changed?
Size: King - 19" X 34", Number of Items: 2
I ordered these last year and loved them! Not too soft not too firm.
I accidentally left mine (my favorite pillow) at an Airbnb. I wanted to replace it and all that was left was this two pack. These are quite softer than the first ones I ordered. Really disappointing as they were my favorite.
