Would buy again
Color: White, Size: Standard (Pack of 2)
This is a good pillow if you like them firm and thin. I let them sit out for 2 days (per instructions).
After having them a week, they've perked up and became more full. I guess they just need time after being in the air. They are softer now but your head doesn't sink thru it. They are actually nice and soft to the touch as well.

On the thin side....
Color: White, Size: King (Pack of 2)
These are described as "high loft" and "supportive", but they are fairly thin/flat and very soft.

Great Support; not too Soft.
Color: White, Size: Standard (Pack of 2)
These are extremely comfortable pillows. I bought them for my every-night use, and they have not disappointed me. They provide great support for one’s head. They mold around one’s neck foot just turn perfect amount of support without being extremely soft. They hold their original manufactured shape easily.

Luxury pillows
Color: White, Size: King(2Pack)
I purchased these pillows to be used as sham fillers, however, the pillows are so great I am now using them for sleeping. The filling conforms to your sleeping position and provides a comfortable sleep. They come rolled in plastic and are paper thin. Once removed, they fluff up beautifully and very evenly. These pillows are high quality and a good value for the price. Highly recommend.

Perfect for Decorative Shams!
Color: White, Size: King(2Pack)
I purchased the VAINOC king size pillows specifically to use inside decorative shams, and they are absolutely perfect for that purpose. They have just the right amount of firmness to keep the shams looking full and well-shaped without being overly stiff.
I love how they instantly made my bed look more polished and put-together. The size fits beautifully in king shams, giving that plush, high-end look you usually see in hotels or magazines.
The quality is great for the price, and they fluff up nicely without going flat. If you’re looking for affordable pillows to elevate your bedding decor, these are a great choice!
