When we first started, we used to be like everyone else – we used high-quality cotton muslin for our pillow casings. Then one day, wanting to be more eco-conscious, we saw a beautiful Bamboo fabric, and said ‘let’s give THAT a try!’. That was the game-changer – Bamboo is sooo silky and soft, that the pillow even more easily conformed to the neck and head, for a far better and much more comfortable cradling effect, and thus a far more restful sleep than the more resistant cotton ever had. This is part of the secret of why so many people say “We have had buckwheat pillows before, but yours is the best one ever..”.
