Awful, very soft not firm at all, shipped in a tiny box
Color: White, Size: Standard/Queen
So soft they were able to fold it multiple times over into a box a fraction of the size of the pillow. Firm description is completely misleading.

Hotel-like comfort at home I bought these pillows from Beautyrest and they really exceeded my expectations. They are very soft but at the same time have good support, which helps you rest better throughout the night. They feel like luxury hotel pillows, especially because of their down-like filling. The jumbo size is perfect and they come well filled, they are not easily crushed. In addition, the cotton cover feels fresh and of good quality. They arrived quickly and well packed. After using them for several days, they maintain their shape and comfort. I definitely recommend them if you are looking to improve your rest without spending too much.

They aren't super firm; they are more comfortable than rigid 😊
Color: White, Size: King Size Set of 2
I bought these pillows, and honestly, I really liked them. They have a medium firmness that helps significantly with neck pain, yet they remain soft and fluffy without going flat during the night. They hold their shape well and have good loft, so you don't have to keep adjusting them constantly. They don't have any unpleasant odor right out of the package, nor do they slide around much inside the pillowcase something I really appreciate. Overall, they feel comfortable and are of good quality for sleeping in any position.
