High End feel.
Color: White, Size: Queen (Pack of 4)
I bought this because I needed to replace old pillows. After using it for a few day I liked that they stayed fluffy and cool all night. My guests loved them too! The quality feels high end. I would recommend it for anyone that likes high end feel without the the high end price.

Comfortable pillows
Color: White, Size: King (Pack of 2)
I bought the king size and they are like a small body pillow. They’re soft n squishy which I like but yet provide the right amount of support. I’ve bought these twice and the 2nd set seemed a little less filled than the first but still comfortable. I would buy again.
