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.

Just give them a little bit of extra time to fluff they will
Size: Standard - 18" X 26", Number of Items: 2
Whatever you do just give it time. When I first open the package of pillows I purchased for they were super flat and for the next couple days they didn't seem to fluff and I was going to do a return. I waited about a week and Amanda these things fluff up and they are nice and sturdy now. I'm glad I waited and gave them time worth the purchase. Recommend

A product that will make a difference!
Color: White, Size: King (Pack of 2)
These king-size pillows are incredibly comfortable and supportive. They are soft enough to feel luxurious, yet they provide great support for my head and neck throughout the night. The king size is perfect for a larger bed and gives the bed a full, hotel-like appearance. The pillows keep their shape well and fluff up nicely after use. I've been sleeping much better since getting them and would definitely recommend them to anyone looking for quality, comfortable pillows.
