Having had my trusty Denton's Low Profile pillow for 7 years it is beginning to suffer the results of hot flushes etc and I am in a bad place with sleeping. I have had the same pillow since they came...
I have cervical spine damage so am careful about pillows.The worst for me are memory foam like sleeping on concrete. Also just a caution be wary of “bamboo” pillows - been a lot of serious allergies reported about new bamboo fabrics esp in uniforms .
