  • What does a king size duvet set include?

    King size bedding sets come with one king size duvet cover and two pillowcases. These will fit standard size pillows and king size duvets in the UK. You’ll need to buy fitted bed sheets to cover your mattress separately.

  • Why choose a king size duvet set from Simba?

    When we created our bed linen, we followed the same approach we used when developing our mattresses and duvets. We chose high performance fabrics, smart materials and continual testing to produce the highest quality linen:

    • Stratos®:'Cool-touch' Stratos® is our patented technology that’s built into our bed linen and fitted sheets. This unique technology is designed to offer instant freshness.
    • Made with soft cotton: We chose this material for its breathability,but not just that: we aim to source our cotton as responsibly as we can, so we’re also a proud member of the Better Cotton Initiative.
    • Easy to maintain: We know you’ve got a busy life and don’t want to spend hours washing bed linen. That’s why we made our king size bedding sets easy to care for.
    • Satin weave: A satin weave is only featured on the 400 thread count linen and gives it a subtle and sophisticated sheen, and also feels soft and sumptuous against your skin.

  • King size duvet cover sizes

    Simba bedding sets in king size fit a standard UK king size duvet. Their dimensions are 225 x 220 cm.

    We also provide bed linen for singledouble and super king size duvets.

  • Pillow case sizes

    Simba pillow cases fit a standard size UK pillow. Their dimensions are: 50 x 75 cm.
