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.

These pillows are quite stiffer than i expected but i guess that means they keep their shape.

This is my third time purchasing these nice and comfortable pillows
Team Name: Pack of 2, Size: Queen - 20" x 30", Color: White, Team Name: Pack of 2, Size: Queen - 20" x 30", Color: White
This will be my third time purchasing these pillows. I and my many guests that have had the opportunity to be able to use these pillows in my guest room have spoke of the wonderful and comfortable they were sleeping with them. And they seem to hold up well and are structured nicely as not to lose there stitching in there construction.
I am very please and feel the cost is quite reasonable to store pillows in there purchase price category.
Kind regards,
J Slade
