These are amazing! I got the king size. They come with two covers, the pleated outside, then another that holds the actual wool. Opening it up and touching the wool, no smell and you can feel the lanolin. This is definitely firm, but adjustable if you want to take filling out. Exactly the right height for a side sleeper. The pillow sleeps cooler than polyester and I don’t look for a cool side constantly. I had to switch from down because of a dust mite allergy and wool is naturally resistant. Great buy, very pleased.
