Thus far, I am enjoying my Casper pillow. As a side sleeper, I find it quite supportive to my head and neck. However, it does become rather warm with extended sleeping on my side... which forces me to toss and reposition the pillow in search of a cool spot. I would recommend the Casper pillow to other people.
I've been sleeping on down for a few years and don't feel enough support. The Casper pillow is an improvement for me. I don't feel the neck strain I've dealt with and am sleeping a bit better. I have noticed that after 10 days or so, it seems a bit flatter than it was at first.
I love this pillow. It’s so comfortable! I am sleeping all night again without waking up several times a night feeling like I’m getting a crook in my neck. I plan to buy them for my guest beds.
