Product details

10% viscose in the filling provides cool comfort in warm conditions. The higher amount of viscose the higher cooling effect and the more temperature regulating the duvet will be.

You maintain an even body temperature and get a restful sleep thanks to the wax infused viscose fibers that absorb excess body heat and releases it back when your body temperature drops again.

You experience a comfortable and dry sleep since the duvet contains lyocell fibers which breathe and absorb moisture.

A good choice if you often feel too warm while sleeping.

The duvet is machine-washable at 60°C, a temperature that kills dust mites.

GreatDeniseWe love it. It's light and doesn't make us hot.5
Does what it supposed toAdeebI'm a hot sleeper, this really helps, keeping me warm enough but not too much that I start sweating.5
Great blanket for hot sleepersLynIts light but still comfy and substantial enough with a duvet cover to make you feel cozy without the middle of the night sweaty mess. Honestly probably the best consistent blanket that I've ever had, and so cheap!5

Perfect for rooms at 23C+JustinI've struggled to find proper bedding for Canadian buildings for a long time. It's challenging when it's winter and your bedroom is 24C because of the ambient heat from the other units seeping through the walls. This is where the STJÄRNSTARR comes in. Although it's made of polyester, I'm truly amazed how suitable it is to keep you the right temperature in a warm room. I used to sleep with a heavier polyester duvet but would always wake up hot at 4am and be unable to fall back asleep. Or, I would sleep with my 20lb cooling weighted blanket and be too cold because it doesn't store enough heat. The STJÄRNSTARR solves both of these problems. This duvet keeps you warm, but not hot, and keeps that temperature nicely through the night. I've never woken up from being too hot with this duvet. The weight is also pretty decent: not too heavy, not too light. I recommend pairing this duvet with some bamboo sheets. Works super well for a warm room. Highly recommended and excellent value for the money.5
Love it!MICHELLEVery happy with it!4

Almost cool enoughDYANAIKEA always has a good range of practical products, and this cool comfort duvet is just right for me, even now in December. I just added a linen sheet and wool blanket for the right warmth.5

Exactly as DescribedcatherineI wanted a light duvet that would suit three of the four seasons, this is perfect.5
DuvetLARAAmazing and cozy5
It lasted 4 yearsSidney R.About an year ago I started noticing small hard particles inside of the pockets of this duvet. The particles slowly increased to the point that they were making it uncomfortable to sleep. If that wasn't enough, this week I noticed a few holes on the duvet and some of those hard particles fell all over the place. I'm over the fence if I would recommend it or not. If you don't mind having to buy it every 4 years, go for it.3
Just What We Were Looking ForJosieOur condo tends to be on the warm side year round. It's been a struggle to find a duvet insert that was light enough, yet offered some warmth. Previously we'd been feeling smothered by ones that were supposed to be "light warm." The STJÄRNSTARR is just what we were looking for. Great price as well.5
Very lightweight, exactly what IMARIAVery lightweight, exactly what I was looking for5


What is lyocell?

Lyocell is a strong and silky-smooth fibre made of cellulose from wood pulp. The soft lyocell fibre is good at absorbing moisture while feeling cool against the skin. That’s why we like to use it for bed linens and as a filling in pillows and duvets to give you a good night's sleep. And just as with any other wood raw material, we strive to use it as smartly and efficiently as possible to avoid waste.

Function solution

Do you often feel too warm while sleeping?

Sleep is essential for our bodies and minds but sometimes it is disturbed when we wake up feeling either cold, or warm and clammy. That’s something our products with cooling effect can help out with. The filling in these products reacts to your body temperature by absorbing and storing body heat when you’re hot, and transferring it back if you get cold. This means your body temperature stays even and pleasantly cool, and you’ll have a more restful night’s sleep.
