This Stay Cool sheet is designed in a deep fitted shape that slips perfectly onto thicker mattresses up to 30cm depth for easy bedding changes. It's crafted from lyocell-rich fabric for a luxuriously smooth feel, with fine natural fibres that wick moisture away for a comfy night's sleep. StayNew™ technology keeps the sheet looking and feeling newer for longer, wash after wash. A non-iron finish makes taking care of your sheet simple.
