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.
