King Size Duvet Cover Sets

King size bed linen can make a significant contribution to the quality of your sleep. By combining innovative technologies and time-tested materials, today’s duvet sets can help you sleep more comfortably and wake up feeling refreshed.

Bed linen is designed to protect duvets, help with hygiene and add style - when you’re sleeping, your body perspires and sheds microscopic skin cells. Bedding therefore protects your duvet and pillows, and ensures they last longer. A king size bedding set also provides technical features and materials which contribute to temperature regulation and comfort. And that means you’ll sleep easier.

  • 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 and includes:

    Stratos®: Stratos® is our patented technology that’s built into our bed linen and fitted sheets. This unique technology is able to draw heat away from your skin, so you never feel too hot under the covers.
    200 or 400 thread count: Simba bed linen is available in either 200 or 400 thread counts. ‘Thread count’ refers to the number of threads found in a square inch of fabric. The greater the number of threads, the softer the fabric feels against your skin.
    100% cotton and environmentally-friendly: All Simba linen is made using 100% cotton. We chose this material for its breathability, and for its coolness to the touch. And, because we’re members of the Better Cotton Initiative (BCI), all our king size bed linen is made using cotton from sustainable and fairly traded sources. Better Cotton is not physically traceable to end products, but BCI farmers benefit from the demand for Better Cotton in equivalent volumes to those we source.
    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 single, double and super king size duvets.

  • Pillow case sizes

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

  • King size duvet cover materials

    Our research & development teams combined clever new technologies with time-tested materials to produce our genuinely innovative king size bedding sets:

    100% cool cotton: Cotton is widely seen as the most suitable bedding linen material thanks to its breathable fibres allowing moisture to evaporate from your skin. All our bed sets use 100% cotton, so you’ll wake up feeling fresh and dry.
    Stratos®: Our unique Stratos® technology helps you maintain a comfortable temperature while sleeping - whatever the temperature. It cleverly draws heat away from your skin until you’re sufficiently cool again. That means you won’t end up feeling hot and clammy under your duvet.
    BCI standard cotton: As members of the Better Cotton Initiative (BCI), we use cotton that has a low environmental impact. The cotton farmers we source from also get a fair price for their product. Better Cotton is not physically traceable to end products, but BCI farmers benefit from the demand for Better Cotton in equivalent volumes to those we source.
