The Fossflakes pillow is like air-conditioning for your head, with an amazing ability to regulate your temperature so you never overheat. Heat is stored in the filling, releasing only as your own temperature lowers, & this cycle repeats itself throughout the night. The idea for this pillow&8217;s unique Fossflake filling came to Danish inventor Lars Foss when he noticed the soft & airy quality of artificial snow. The pillow therefore has the luxuriously indulgent feel of softest natural down. The filling is evenly distributed & will never clump even after repeated washing, so the Fossflakes pillow will keep its shape & volume for years.
