Belledorm\'s 200 thread count fitted sheets in white boast the natural qualities of cotton such as temperature regulation and moisture wicking combined with the durability and longevity of polyester. This fitted sheet is extra deep with a depth of 38cm (15inches). As mattresses get deeper with the addition of mattress toppers and memory foam, extra deep fitted sheets allow for a secure, snug fit that will help to avoid your sheets slipping or coming off during the night. It is recommended that you buy your fitted sheet to sit 2-3 inches (8cm) deeper than your mattress. Available in a wide range of colours and sizes, this easy care bedding has a crease resistant finish to minimise wrinkles, and requires minimum ironing which is perfect for busy households. This superior percale bedding also has a soft laundered finish that gets softer with each wash. Matching pillowcases also available.
