  • Why choose a king size fitted sheet from Simba?

    If you’ve bought a luxuriously sized bed, you really need the sheets to match. Made from soft cotton, Simba’s king size sheets are breathable and durable, with a lightweight percale weave and an exquisitely soft satin weave.

    But it’s not just the high-quality cotton and an excellent thread count that make our king size sheets unique. It’s also got our patented Stratos® fabric technology, which is designed to help keep you fresher as you sleep. This ground-breaking technology assists with drawing heat away from the body, like your very own bed thermostat.  

  • What size is a Simba king size fitted sheet?

    Our king size fitted sheets are W150cm x L200cm, the standard size for a UK King size bed, and they’re suitable for mattresses up to 40cm deep.

    Simba also offers fitted sheets in single, double and super king size.

  • What materials do we use to make our king size fitted sheets?

    Our fitted king size sheets combine the latest sleep technology with a commitment to a more responsible sleep to help you rest easy at night. Alongside being soft and comfortable, we aim to source our cotton as responsibly as we can. That’s why we’re a member of the Better Cotton Initiative.

  • What’s the thread count of Simba king size sheets?

    Thread count refers to the number of threads per square inch and is a measure of how tightly woven the fabric is: usually a higher thread count provides softer and more durable sheets. But the quality of the cotton and the type of weave is important too.

    Our performance sheets come in two thread counts and weaves:

    • 200 Thread Count Percale Weave Crisp, light and just right, our percale weave sheets have a simple criss-cross pattern that gives them a smooth and durable structure.
    • 400 Thread Count Satin Weave These soft and luxurious sheets have a top surface sheen, and drape extremely well.. Our satin weave sheets are a bit heavier than percale, making them even more.

  • How do you wash a king size fitted sheet?

    Just pop your bed sheet in the machine at 40°C and tumble dry it on the lowest heat seating.
