I was excited about the Casper pillow, but was honestly disappointed. Maybe it is just about personal preference, but I found the pillow to be way too soft and not nearly "fluffy" enough. I felt like when I placed my head on the pillow, it was basically touching the bed. I was constantly bunching it up to provide bulkier support. If you prefer thinner pillows, this is the one for you.
The pillow is great. I'd say when you're laying on it, it actually becomes quite a bit thinner, the same way a feather pillow becomes more squished. If you want a thicker pillow, almost like a foam pillow, this isn't what you're looking for.
Just not what I wanted the pillow was way too soft for me. It made my neck hurt pretty bad also my wife wasn’t impressed. I returned both pillows. The mattress is great tho
