Don’t judge by the size
Color: White, Size: Standard (Pack of 2)
I don’t write reviews here typically but I’ve been on the pillow hunt for years with no luck. Mine are always lumpy and misshapen or too soft or too firm. Don’t judge this pillow by how it looks though because I saw it and thought for sure I wasted money. They are small and not fluffy at all. But OMG I laid down on it and it’s the most comfortable pillow I’ve had in years. Memory foam didn’t work for me but this simple little pillow just allowed me some great sleep. Very happy with this purchase. It’s a simple, no frills pillow that’s perfect for this side sleeper that doesn’t like a too soft pillow.

Superb!!!!
Color: White, Size: Queen (Pack of 4)
If I could give more than 5 stars I would. I purchased these beauties 6 months ago and they are still fluffy and firm. I'm amazed by the price point. I will definitely re-order for the guess bedroom.

Soft and comfortable, NOT firm.
Color: White, Size: Queen (Pack of 2), Color: White, Size: Queen (Pack of 2)
Overall, these are comfortable pillows for the price, especially if you prefer something soft rather than firm.
The pillows arrived vacuum sealed, which is pretty standard. Once opened, they fluffed up well after some time and looked full enough to use. Right away, they felt soft and plush, and sleeping on them was comfortable from the first night. In terms of comfort and support, these pillows are definitely on the softer side. They work well for side and back sleeping if you like a pillow that you can sink into a bit. They’re not firm or dense, but they’re still cozy and gentle on the neck and head.
After a few days of use, I did notice that the pillows started to look a little lumpy and uneven. The filling tends to shift, so they don’t hold their shape perfectly and need regular fluffing. That said, even when they look a bit misshapen, they’re still soft and comfortable to sleep on. If you’re someone who needs strong neck support or prefers a firm hotel-style pillow, these may feel too soft. However, if comfort and plushness are your priority, they do the job well.
For the price, I think they’re a good value. They’re not luxury pillows, but they’re comfortable, decent quality, and perfectly fine for everyday use or a guest bed.

Would buy again
Color: White, Size: Standard (Pack of 2)
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.
