The AeroSleep fitted sheet was specifically designed for the AeroSleep mattress protector. • Contrary to cotton fitted sheets our fitted sheets do not absorb moisture. This keeps the structure open so that the air permeability of our mattress protector is 100% guaranteed, even with minor leaks. • Moreover, the long-pile structure feels wonderfully soft to the touch. The AeroSleep fitted sheet is washable at 60°C and is available in all sizes and several colours.
