Double Duvet Cover Sets

A high quality double bed duvet set can make a big contribution to your sleep. Through the combination of innovative design and time-tested materials, today’s duvet sets are more comfortable and luxurious than ever.

Double duvet sets are a perennial favourite for both couples and individuals. They have a double function of protecting your duvet and pillows, while also enhancing sleep quality. When you’re asleep, your body perspires and sheds microscopic skin cells - your bed linen is there to protect your bedding so it lasts longer. At the same time the pure cotton and technical features contribute to temperature regulation and comfort, helping you get a better night’s sleep.

  • What does a double duvet set include?

    A double bedding duvet set comes with one double duvet cover and two pillowcases. If you’re looking for UK bed linen, these will fit standard size double duvets and pillows. You’ll need to purchase additional pillowcases and fitted bed sheets separately.

  • Why choose a double duvet cover set from Simba?

    When we designed our bed linen, we took the same approach we take when re-engineering our double mattresses and duvets. We’ve built in smart materials, used high performance fabrics and R&D to produce truly unique bedding. Our double bed linen sets include:

    Stratos®: We’re rather proud of our patented Stratos® technology, which is built into the fabric. It cleverly draws heat away from your skin in order to regulate your body temperature, so you’ll never feel too hot in bed.
    200 or 400 thread count: All our double bed linen is available in 200 or 400 thread counts. Thread count simply refers to the number of threads woven into a square inch of fabric. The higher the number of threads, the more sumptuous the fabric feels on your skin.
    100% cotton, 100% sustainable: Our double bed set range is made from 100% cotton - giving you superior comfort and coolness. Cotton is naturally breathable, allowing all moisture to evaporate, meaning you won’t wake up feeling clammy. Because we’re members of the Better Cotton Initiative (BCI), all our double bed linen is made from raw materials that come 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 look after: We know you’ve got a busy life and don’t have endless time to spend cleaning your sheets. That’s why we made our double bedding covers easy to care for.
    Satin weave: A satin weave is featured on the 400 thread count bed linen only. It is a specific kind of weave that gives the linen an attractive glossy sheen, while being especially soft to the touch. While our 200 thread count linen has a crisper feel.

  • Double duvet cover materials

    Our engineers combine ingenious new technologies with time-tested materials to produce a genuinely unique double bed linen that helps you sleep better and wake up refreshed:

    100% cool cotton: Cotton has been used in duvet covers for decades thanks to its breathable fibres allowing moisture to evaporate from your skin. Because we use 100% cotton, you’ll wake up feeling dry and refreshed.
    Stratos®: Stratos® is our patented technology which is built into Simba bed linen, and is designed to help you maintain a comfortable temperature all night. It draws heat away from the skin until you’re sufficiently cool again, so you avoid feeling hot and clammy.
    BCI standard cotton: We’re proud members of the Better Cotton Initiative (BCI). This means the cotton used in our double bed sets has a low environmental impact and cotton farmers get a fair price for their produce. 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.
