Good overall
Color: White, Size: Standard (Pack of 2)
Bought these for our guest bedroom. They are quite overstuffed, so if you like full pillows this will be your thing. As such they are dense and firm. The height is a bit much if you are small framed, but are comfortable overall and stay cool enough to be nice in the summer.

Finally Found Pillows Everyone Loves
Color: White, Size: King (Pack of 4)
I LOVE these pillows. I bought the king-size set and ended up liking them so much that I want them on every bed in the house.
They’re soft but still supportive, and they actually work for different sleeping positions, back, side, and stomach sleepers. They don’t go flat, but they’re also not overly stiff, which is such a hard balance to find. I throw them in the washing machine which makes them super easy to wash! The size is true to King!
They feel cool and hotel-quality, and the down-alternative fill is great if you don’t want real feathers. I wake up without neck pain, and they keep their shape night after night.
If you’re picky about pillows (like I am), these are absolutely worth it. Comfortable, affordable, and a great value for a set of four.
