I bought this pillow thinking that it would be adjustable to the level of firmness and fill that I want. Unfortunately this is absulotley untrue. No matter how much fill i remove it stays the same because the fill interlocks into a brick. It doesn't matter how much I shake or fluff the filling becomes a solid surface with no give whatsoever. I am very mad at myself for spending so much on something that is not returnable. If you are looking for a very firm pillow this is for you. If you are looking for something adjustable look eslwhere and don't waste your money. Also the cooling cover is useless and does not keep the pillow any cooler than a regular cover but you will need something because the basic cover on the pillow is very thin.
