These are very thick pillows.
Item Package Quantity: 2, Size: Queen
Exactly as advertised. They are very firm and very thick. They're too thick for me to be able to use as bed pillows. However, they seem to work pretty well as cushions in my papasan chair on top of its normal cushion also work very well as decorative pillows.
I'm still giving them four stars because they're exactly as advertised and they seem well made. My only complaint is that they're just too thick. And that's definitely not the fault of the pillows or the pillow maker.

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.
