Too firm
Color: Classic White, Size: King (Pack of 2)
These pillows are good quality but are firm. They also are 90% feathers, which makes them feel “crunchy”

These are a keeper!
Color: Classic White, Size: Queen (Pack of 2)
I've been looking for this for years. I love these pillows. Ordered 2 queen size and they are amazing. Great support while still allowing my head to sink into it. It's hard to explain how it can be both firm and soft at the same time but it is. LOVE!

Comfortable pillows
Color: White, Size: Standard (Pack of 2)
These pillows are great. Not too soft or to hard. They need to be in the dryer for about 15 minutes to fluff up. Perfect buy!

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.
