I've had mine about 2 years and love it. Didn't like it at first but once I learned how to adjust it each night before bed it has been my favorite.
Have to wash and dry also every so often.. about every 2 to 3 months is good. At first I did think it was aweful but my dad had purchased one and told me to give it time and I will love it. He was right.
To me it felt like little knots inside and I thought no way I'll like this pillow but after a while I didn't even feel that once I learned to adjust...make sure you put in dryer before using to activate the material inside. Hot dryer
