Fans of down and down-alternative pillows: the Standard size Purple Cloud(TM) Pillow is for you. We've upgraded the cloud-like comfort of down by filling our Purple Cloud(TM) Pillow with hypoallergenic, ultra-fine gel fibers that won't clump, trap heat, or flatten over time. The result is plush cushioning that molds to support your head and neck. Purchase comes with one pillow.
