Stratos® active temperature regulation
Aerelle® cool night fibres dissipate heat
Breathable cotton from BCI sources
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 it's 100% recycled, hypoallergenic and doesn't use any animal products.
The super-soft filling is stitched evenly into square pockets so the comfort reaches every corner. No more lumps and bumps in the night and no more arguing over who took the good bit of the duvet.
We rest better when we know your honest opinion of us. Check out reviews from Simba sleepers below, and please add your own.
Absolutely - it's designed that way. In the old days, duvets were assessed using tog ratings so you had warmer ones for winter and cooler ones for summer. With widespread central heating, that no longer makes sense - your winter bedroom is probably warmer than your summer one!
Plus with two different temperature regulating technologies in the Simba Hybrid® Duvet, using an out-of-date way to assess how warm it is doesn't account for the fact that it's specifically designed to be the perfect all-year-rounder.
Some say that higher thread count means higher quality, but that's a bit of a yarn. For the Simba Hybrid® Duvet we've focussed instead on using high quality threads sourced via the Better Cotton Initiative, which promotes more sustainable methods and better working standards for cotton producers.
It's smooth, soft and provides an excellent fabric base for our innovative Stratos® technology. So you get the breathability of quality cotton as well as active temperature regulation.
Stratos® is our new technology designed to help you keep your cool.
It’s a phase change technology, designed to go above and beyond to regulate your temperature while you sleep. It works a little bit like the ozone layer, which keeps the Earth’s temperature in check by absorbing the excess heat from the sun. If you get too hot during the night, Stratos® absorbs your body heat to cool you down. If you get too cold, it releases the heat to warm you up.
You'll know which side of your duvet or pillow is the high-tech one because we’ve added handy colour-coded piping along the edges. Blue side = cool side.
