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.

100% Cotton Pillows .
Color: White, Size: Queen Size Set of 2, Color: White, Size: Queen Size Set of 2
These pillows feel soft and fluffy without being too flat. They provide nice support for the neck and feel comfortable whether sleeping on your side or back. After several nights of use, they still keep their shape well and don’t feel too warm during the night. The set comes with two pillows, which makes it really practical for the bed.

Luxury Comfort and Perfect Support – Best Pillows Ever!
Color: White, Size: King Size Set of 2
I recently purchased the Serta Hotel collection Pillows White Goose Feather Down Fiber Gusseted, and I couldn’t be happier with my choice! These pillows are the perfect balance of softness and support — plush enough to feel luxurious, yet firm enough to keep my neck properly aligned all night. The gusseted edges really make a difference, helping the pillow hold its shape and look full even after weeks of use.
The quality of the materials is excellent — the outer cover feels smooth and breathable, and there’s no feather poking out like with cheaper options. I also appreciate that they fluff back up easily after use, making the bed look hotel-perfect every morning.
If you’re looking for comfortable, high-quality pillows that provide great value for the price, I highly recommend these. They’ve truly improved my sleep!

Good quality pillows
Color: White, Size: Queen Size Set of 2
These are very soft and supportive as advertised. W find them a little too thick for my taste (why I only gave 4 stars), but personal preference is very subjective with pillows. They are well made and high quality, and am happy with my purchase.

Overall, not that comfortable!
Color: White, Size: Queen Size Set of 2
Only okay. I find these pillows to be heavy, and not very conforming. Overall, not that great.
