Explore Our Collection of Super King Size Duvets

To make sure no sleeper gets left behind and can experience what Simba’s award-winning duvets are all about, we engineered three unique models that you can choose from. They include:

  • The Simba Hybrid™ - With a TOG rating of 10.5, this is our all-season duvet. It is the perfect choice for sleepers who get either too warm or too cold and can’t maintain a comfortable body temperature at night.
  • The Simba Hybrid™ 3-in-1 - This is our most flexible duvet to date. It includes a 7 TOG duvet for milder spring and autumn nights and a 3.5 TOG duvet for the summer. You can also join the two together and get a duvet with a 10.5 TOG.
  • Simba Summer Hybrid™ - This is our lighter 4.5 TOG duvet that’s perfect for the summer (or for hot sleepers). It’s filled with down-like Simba Renew Bio™ fibres and is designed to offer cool and gentle comfort at night.

Key Considerations When Choosing a Super King Size Duvet

Choosing the right super king-size duvet is crucial, as it can be the difference between being too cold or too warm at night and sleeping in dreamy comfort all night, every night. To help you choose the right duvet, some of the key considerations that you need to take into account include:

Tog rating

The TOG rating is the first key consideration that you need to think about. If a duvet has a lower TOG rating, that means it’s lighter and better suited to warmer conditions, such as during the summer. On the other hand, a duvet with a higher TOG rating provides greater insulation, making it more suitable for colder months when you need that extra bit of warmth.

Fill type

The type of filling used in your duvet will play a major role in how comfortable it is and how well it performs. Natural fillings, such as down or cotton, are known for their softness and breathability, while synthetic fillings are hypoallergenic and easier to wash.

Sleeping preferences

Everyone sleeps differently, so your sleeping habits and personal preferences should play a key role in choosing the right super king size duvet. If you’re a hot sleeper, you should consider a lighter and more breathable duvet. If you’re someone who always feels cold, especially during the winter, consider a higher TOG duvet.

Why Choose Simba’s Super King Size Duvets?

When you choose a Simba super king size duvet, you can enjoy comfort that’s out of this world from the most innovative duvet brand in the UK. We take sleep extremely seriously and have worked tirelessly to create a range of super king quilts that will keep you comfortable and at the perfect temperature all night long. Other reasons why you should choose our super king size duvets include:

  • We have three different super king quilt models to choose from
  • We offer free next-day delivery to most postcodes in the UK
  • We offer a 1-year guarantee on all our super king-size duvets
  • Each duvet is made from industry-leading sleep tech and premium materials
  • You can split the cost of your duvet thanks to our flexible finance options

  • What size is a super king duvet?

    Super king duvets are 220cm (L) x 260cm (W) and are the perfect size for super king beds. You may notice that they are slightly larger than the standard super king-size bed, but that is because they’re designed to provide extra coverage on either side of the bed.

  • How much bigger is a super king duvet than a king?

    A super king-size duvet measures 220cm (L) x 260cm (W), while a king-size duvet measures 220cm (L) x 225cm (W). The former option is 35cm wider compared to the latter, giving you an extra 17.5cm coverage on each side of the bed.

  • Is it worth getting a super king duvet for a king bed?

    Most people tend to pair their king-size beds with a king-size duvet, as king-size duvets are already larger than the surface of the bed. However, if you feel like you could benefit from the additional 35cm in width, then you can absolutely opt for a super king duvet instead.

  • What tog super king duvet do I need?

    The TOG duvet you need will depend on the season and your personal sleep preferences. If you are someone who tends to get warm and uncomfortable at night, a super king duvet with a lower TOG rating would be ideal for you. If you get cold easily, on the other hand, you should look for a super king duvet with a higher TOG rating.

  • Can I machine wash a super king duvet?

    Whether your super king duvet can be washed in a washing machine will depend on the materials it’s made from and the manufacturer’s instructions. In most cases, you should be able to wash your duvet - even if that means washing it on a 20 °C or a 30 °C program.

    At Simba, we’ve made all our super king-size duvets easy to care for. You can wash your duvet in your washing machine at a maximum temperature of 40 °C and tumble dry it on the lowest setting.

  • What are Simba super king duvets made from?

    To make our award-winning super king-size duvets, we use a variety of premium materials and sleep technologies. To give you an example, our Simba Hybrid™ and Simba Hybrid™ 3-in-1 super king-size duvets feature three layers.

    The first layer is a cotton cover combined with our Stratos® technology to help keep you at a comfortable temperature through the night. Next are multiple layers of Simba Renew® fibre fillings, which are tiny fibres that are made using recycled materials. Finally, there’s a layer of exquisitely soft cotton, which is blended with incredibly fine and airy Modal fibres.

  • What technology is in a Simba super king duvet?

    As sleep obsessives, we’ve designed all the super king duvets for sale here at Simba to be as clever as they are soft. Here’s how we’ve done it:

    • Stratos® technology - This astronaut-inspired technology is designed to encourage heat to dissipate away from the body while providing a ‘cool to the touch’ sensation.
    • 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 a fabulous warmth-to-weight ratio.
    • Modal fibres - Modal fibres are soft and airy and can help to wick moisture away from the body to help you feel cooler.
