  • Why choose a Simba super king duvet?

    Enjoy comfort that’s out of this world in one of the largest duvet sizes available in the UK from the most innovative duvet producer. We take the business of sleep science seriously and work tirelessly to create a duvet that keeps you comfortable, covered and at perfect degrees all night long.

    There’s also free delivery and returns and a one-year guarantee on all our Simba Hybrid Duvets.

  • What are Simba super king duvets made from?

    As well as being the most technologically advanced duvet on the market, our super king duvets are made from ethically sourced and sustainable materials that won’t keep you up at night.

    Our Simba Hybrid® and Simba Hybrid® 3-in-1 super king-size duvets feature three layers. The first layer is a 100% Better Cotton cover combined with our Stratos® heat control technology to regulate your temperature through the night.

    Next are multiple layers of Simba Renew® fibre fillings, tiny fibres that are made from 100% recycled materials. Finally, there’s more exquisitely soft Better Cotton , which is blended with incredibly fine and breathable Modal fibres made from natural and renewable resources.

  • What technology is in a Simba super king duvet?

    As sleep science obsessives, we’ve engineered a technologically-driven duvet that’s as clever as it is soft. Here’s how we’ve done it:

    ● Stratos heat control technology - This astronaut-inspired technology is activated by rising skin temperatures and draws heat away from the body while providing an instant cooling sensation. It deactivates once your cooling is complete to keep you at the perfect temperature all night.
    ● Simba Renew clusters - These tiny 3D clusters create the silky and smooth down-like softness inside every Simba duvet. We comb, multi-layer and fold them like never before to create an incredibly light duvet with unbeatable thermal efficiency.
    ● Modal fibres - Our Simba Hybrid 3-in-1 super king duvet is blended with Modal fibres. They’re exceptionally breathable and help to wick moisture away from the body to keep you in total temperature-controlled comfort.

  • What tog ratings are Simba super king duvets?

    Between our Simba Hybrid and Simba Hybrid 3-in-1 super king-size duvets, we have the perfect tog rating for every season and sleeping type.

    The Simba Hybrid super king duvet is 10.5 tog, making it a great all-season duvet and a lightweight, comfortable pick for sleepers who have trouble maintaining a consistent body temperature at night.

    The Simba Hybrid 3-in-1 super king duvet includes a 7 tog duvet for milder spring and autumn nights and a 3.5 tog duvet for the summer. Just join them together to create a 10.5 tog duvet that’s just right for winter.

  • What size is a super king duvet?

    Simba super king duvets are L220cm x W260cm, which is the standard duvet size for a UK super king bed.

    We also sell Simba single, double and king size duvets.

  • How to wash a super king duvet

    Like all of our Simba Hybrid duvets, you can wash your super king duvet in your washing machine at 40°C and tumble dry it on the lowest heat. We recommend using a 9kg machine or larger when washing a super king duvet. It should fit in the drum loosely, allowing the water and detergent to flow through the drum and duvet freely.

  • What way round does a super king duvet go?

    King size and super king duvets are the only duvets that are wider than they are long. When making your bed, the longest side of the duvet should go horizontally across it.

  • Is there a bigger duvet than super king?

    The super king duvet is one of the largest duvet sizes in the UK. However, there’s also an emperor-size duvet that’s L235cm x W290cm. It’s rare to find emperor beds in people’s homes but they are popular in hotels.
