- Super King Size : 260 x 220 (cm)
Our all-season Hybrid Super King Size Duvet has you covered all year round.
The temperature regulating Stratos® outer layer and heat dissipating fill are designed to keep you in your comfort zone.
Forget tog ratings. Our super king size duvet is perfectly balanced to keep you comfortable whatever the weather.
Square quilting brings hybrid comfort to every corner and quick-fit tabs mean less time making your super king size bed and more time lying in it.
Bed down in three layers of super king size duvet hybrid comfort for a great sleep wherever and whenever.
Intelligent temperature regulation and a fill so outrageously comfortable you'll want to hunker down for days in your super king size duvet.
To drop off to sleep, you need to cool it. Staying a steady temperature under the super king size covers helps you stay asleep but you'll run hot and cold. So we looked to the heavens for inspiration. Astronauts have always dealt with extreme temperatures - the moon's surface rockets from -173°C to 127°C and back again. So just like space suits, our Stratos® cover uses phase change technology to respond to you and keep you feeling just right, all night.
The super king size duvet super-soft filling is stitched evenly into square pockets so the comfort reaches every corner. No more lumps and bumps in the night.
Stratos® is an advanced fabric technology that takes the heat. Inspired by the phase change material developed for space suits, Stratos® reacts to your temperature, absorbing heat from you when you get warmer, and releasing it back to you as you cool down. So you can chill out all year round.
If we didn't know better we'd say there was magic in these microcapsules. They absorb the heat from the environment around them and cleverly store it up ready to release if your temperature drops.
Aerelle® Cool Night fibre is embedded with semi-conducting minerals that draw heat away from the body, helping you stay comfortable all night long. Plus your super king size duvet is 100% recycled, hypoallergenic and doesn't use any animal products.
Our Hybrid pillows and super king size duvets use cotton sourced from suppliers signed up to the Better Cotton Initiative, which promotes more sustainable production and higher working standards. They’re also vegan-friendly since the fill has no animal products, instead being made with recycled materials certified by the Global Recycling Standard.

A super king size duvet measures 260cm x 220 cm x 4cm, making it the perfect size for king size, super king size and emperor size beds.
Super king size duvets are the ultimate in household harmony - they're simply too big to steal! You won't want to change this one regularly, so an option that's warm when it's cold and cool when it's hot is recommended for blissful comfort all year round. You'll also want to watch out for a well-distributed filling - that's where filling sewn into pockets will help, so you're not constantly shaking it out.
Traditional feather and down super king size duvet: Duck feathers and down have been a traditional favourite because they combine lightness with cosiness and heat regulatiion. Not suitable for those with a feather allergy, it's important to check that the feathers and down have been ethically sourced.
Hollowfibre super king size duvet: Fibre fillings can be an economical vegan friendly choice, and there are hypoallergenic options for sensitive sleepers. Plus it's easily machine washable.
Microfibre super king size duvet: Finer and softer than hollowfibre, microfibre duvets are a popular synthetic alternative as they're often hypoallergenic, light and soft.
Wool super king size duvet: Like feather and down, wool is a natural filling that is good for heat regulation, and additionally has some moisture-wicking properties. It is much heavier, however, and is also not vegan-friendly.
Silk super king size duvet: Silk is sometimes blended with other fillings in duvets as a soft, natural, breathable fabric. It's an expensive choice, but there are more budget-friendly, equally effective plant-based alternatives like TENCELTM on the market.
You might have heard that your duvet's tog rating is a mark of quality - it's not! Tog ratings were originally developed to indicate thermal insulation - that is, how warm a duvet is. So in theory you want a higher tog in winter and a lower tog in summer. The only problem is, with centrally heated housing, that's not necessarily a useful guide to follow! And now with major advances in temperature regulating fabric and filling technology, tog ratings often aren't necessarily an accurate picture of how cosy yet cool your duvet could be. Properly engineered for comfort, a duvet that appears to have a high tog rating could be perfect all year round - so it's more important to look into the way your duvet is designed and what it's made of.
We've taken the best of traditional duvet design and made it out of this world, with innovative heat regulating fabric technology originally designed for space suits. One side of our ethically sourced feather and down super king size duvet is printed with Stratos® phase change technology, which absorbs, stores and releases heat as you need it. Since it always responds to you, it's just right all year round. Plus the filling is sewn into pockets so it's always evenly distributed.
