My mom had one of these type pillows for over 20 years. I have been looking for this pillow and FOUND IT!!! It will NEVER go flat and will be as comfortable as any pillow you have ever used. It has a springy type feel. Your head sinks in but it is also firm enough to give you good neck support. The pillow has a removable, washable cover also. You will not be dissapointed. I bought two, two years ago and they are like brand new, and I use them every night. It is almost comparable to memory foam without being "hard " like. A must have for anyone any age!!!
