Filled with the finest and largest white goose-down clusters and with a clever feather-rich inner core this luxurious pillow cocoons the head in supreme softness with just the right amount of support. The Soft is an ideal choice for back and front sleepers while the Medium is great for people with a slighter build and smaller shoulders who sleep on their side thanks to its denser core.As with all pillows the best choice depends on personal preference build and how you sleep.
