Dive into perfectly comfortable sleep with the DreamSmart Sapphire Clean Cool Pillows. Stay healthy and clean with the anti microbial treatment to the fabric. Stay cool on either side of the pillow: Side #1 has a luxuriously cool-to-the-touch circular knit panel. Side #2 has a luxuriously soft and wicking circular knit that keeps you dry and cool. Made in two height profiles: Low Profile (11 cm) for stomach and back sleepers and Hi Profile (14 cm) for back/side sleepers. The memory foam feel is built to perfection as well: soft at first but with the perfect amount of support. These pillows will be clean, cool and comfortable all night long.
