This is a good pillow if you like them firm and thin. I let them sit out for 2 days (per instructions). After having them a week, they've perked up and became more full. I guess they just need time after being in the air. They are softer now but your head doesn't sink thru it. They are actually nice and soft to the touch as well.

On the thin side....

Color: White, Size: King (Pack of 2)

These are described as "high loft" and "supportive", but they are fairly thin/flat and very soft.

Great Support; not too Soft.

Color: White, Size: Standard (Pack of 2)

These are extremely comfortable pillows. I bought them for my every-night use, and they have not disappointed me. They provide great support for one’s head. They mold around one’s neck foot just turn perfect amount of support without being extremely soft. They hold their original manufactured shape easily.

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.
