Our bamboo adjustable pillow conforms to your shape for a perfect nights sleep. The bamboo cover has temperature regulating properties to help keep you cool at night. This pillow is great for side, back or even stomach sleepers since you are able to adjust the fill density yourself. Each pillow comes with an extra bag of our down alternative filling so you can add or take away just the right amount for the perfect pillow. If the pillow is too soft, just add some filling. If the pillow is too full, just open the zipper and remove some filling. If a few years down the road the pillow becomes too soft you can always add more fill.
