Fluffy, Supportive, and Perfect for a Great Night’s Sleep
Team Name: Pack of 2, Size: Queen - 20" x 30", Color: White
I purchased the Premium Queen Size Pillow set of two on a flash deal, and I’m so glad I did! These pillows have the perfect balance of softness, thickness, and firmness. At about nine inches thick when fluffed, they easily compress down to about three inches, thanks to the down alternative fill. This makes them incredibly supportive without pushing my neck up too high. The down alternative filling gives just the right amount of “nestle,” letting my head and neck sink in comfortably, which has improved my sleep quality tremendously. They’re fluffy yet still provide that soft firm support I love. Another big plus is washability. I can toss them in the wash, and they come out looking and feeling like new. For a 2-pack, they’re a fantastic value for money, and I would purchase them again.

Premium Pillows
Team Name: Pack of 2, Size: Queen - 20" x 30", Color: White
Purchase these as a gift for1 of my children that had terrible pillows. To say she was pleased would be an understatement. She said that these were some of the softest and most comfortable pillows she had ever used. They remained puffy while conforming comfortably to her sleep style. She was absolutely in love and I would definitely purchase again.

stiff pillows
Team Name: Pack of 2, Size: Queen - 20" x 30", Color: White
These pillows are quite stiffer than i expected but i guess that means they keep their shape.
