These are so comfy. I love them. They have made my life so much better. I have really bad insomnia. I was also getting neck pains from my old pillows. These are just the best for sitting up and sleeping. I can not tell you how much these changed my life. They are worth a shot if you are looking for something. 10 out of 10.
