When we need to, we are able to refill this natural stuffing to our liking. I love that these pillows are adjustable...no need to guess which fill level you want when confronted with all that choice in the pillow aisle. Rather than adding fluff to the pillow, one could also remove some if it was too fluffy upon arrival. We've had our pillows for years + mine truly is the best one I've ever slept on.
Love,
Jane
