Not firm at all
Style: Medium/Firm, Size: Queen
The pillows are listed as firm and they are not fi at all. My kids will enjoy sleeping with them, but not my husband or myself. Total disappointment!

Awful, very soft not firm at all
Color: White, Size: Standard/Queen, Color: White, Size: Standard/Queen
Ordered the Serta Ocean Breeze Breathable Medium/Firm Bed Pillow. The listing is misleading—it shows two pillows in the photo, but only one is included for the $47.00 price. The pillow arrived vacuum-packed and was extremely flat. Despite efforts, I couldn't fluff it back to a usable thickness; the total loft was only about 4 inches. Very disappointed with the quality and presentation. Returned item.

Only 1 pillow
Color: White, Size: Standard/Queen
It is misleading that the picture shows 2 pillows but you get 1 pack, that would mean 2 pillows but what do I know, huh? This is only 1 pillow.
