I love the wool-filled bed! It has natural fibers and a light, lovely wool scent. The dog and cat both love to lay on the bed, so they seem happy with the choice too. In the future, I would buy one size larger bed insert for my dog and then a size smaller duvet so that the bed is fluffier. I have a large dog (~80 lbs) but doesn't like to stretch out too much, so getting the extra large bed was probably unnecessary for him.
