The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then.
They both needed a firm pillow that is not super soft, firm but not achy.
Finally found the perfect one.

Super comfortable!!!!
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
They are super soft and large; they come vacuum-sealed and expand very quickly. They aren't heavy, and they are incredible for sleeping and watching TV in bed.

Comfort and Quality
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
These pillows are very comfortable. They hold their shape well throughout the night and have greatly improved my sleep. Plus, the quality of the materials is excellent. Highly recommended!

Terrible pillows
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
These pillows might be fine if you need them for a decorative sham, but definitely NOT to sleep on. They are super lumpy and soft, days after taking them out of package. It seems like there are just bunches of cotton strips in a row that are hard to fluff. They are also dark in some areas, so it looks like the pillow is stained, when in fact it's whatever material the stuffing is. I can't return them because they won't fit back in the box. Super disappointing.

Comfortable from the first night
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
I found them comfortable and with good support for the head and neck. They are wide in size and feel soft when lying down. After several days of use they continue to retain their shape without problem.
