I've been looking for a firm pillow that didn't cause sweating for ages. This was perfect. Took a couple of nights to get used to it but after that it was great. I have a number of medical condition that cause sleepless nights but to be honest, I've slept like a baby since getting this pillow. My husband used to ball his pillow up until it eventually looked more like a bolster but he's also found this fantastic. Also, his snoring and fidgeting hasn't kept me awake!!! Result!
