A true medium firm pillow
Size: Queen - Pack of 2, Style: Soft, Configuration: Pillow
I like a medium pillow that lets my head sink in a little bit so my neck isn't cranked at an angle but not to the point where it sinks in completely. You can also scrunch it a little bit. Also love that it's queen size, as most queen sheet sets for come with queen pillow cases, not standard. I am surprised it worked out, very happy with it.

how good the product is
Item Package Quantity: 4, Size: Standard
These pillows are soft, fluffy, and surprisingly supportive for the price. They’re comfortable no matter how you sleep — whether on your side, back, or stomach — and they maintain their shape well overnight without going flat. The fabric cover feels smooth and breathable, keeping things cool through the night.
After a few days of fluffing and use, they settle nicely into a perfect medium firmness. They also wash and dry easily without clumping.
Overall, a great‑value pillow set that offers comfort, versatility, and quality — ideal if you need an affordable yet cozy bedding refresh.

Firm and comfortable
Item Package Quantity: 2, Size: Standard
These pillows are well made. Firm, yet comfortable. I am pretty rough with my pillows. I toss and turn frequently. After one year, they are still holding up.

Quite good. I am actually surprised. Too small for queensize
Item Package Quantity: 2, Size: Queen
These pillows are actually good. After reading a ton of reviews I pulled the trigger on these. I was 100% sure I was going to receive bad quality pillows (too flat or too thick). They do take 24-48 hours to firmen up. Let's see if they flatten out in a few weeks or if they hold up. My wife said the pillow was too thick and it raised her head too much. I don't agree, I sleep perfect on these, no neck pain in the morning.
Update 04/24
These are actually quite small to be considered queen pillows. They have become firm over the last few days.
