Terrible flat as a pancake pillows. Look as if they have been slept on for 20 years, I’m not joking. 
I can’t be bothered sending back as it’s to much trouble. They are literally filled with dog toy stuffing, you know that white cotton filling that your dog pulls out of their toys after they destroy them.. If that is a “down alternative” than its surprising to me. Shocked wayfair even carry’s such a terrible product. Not even deserving of - star but they make you check a star.
