A nice comfy pillow.
Team Name: Pack of 2, Size: Queen - 20" x 30", Color: Blue Edge
A Recently had a pillow that broke and needed a new one. I love this pillows firmness. This pillow is expensive just for one, but I gave the other pillow to my brother as I thought if one of his pillows falls apart, he has one too. I’m not sure how durable this pillow is, but it looks pretty sturdy. It does get flat within 3 weeks after opening. It does not cool.

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.

I love these pillows. At first they felt a little firmer than I wanted but they quickly became very comfortable and just want I wanted. Seems to be great quality.
