The only person taking your duvet for a spin should be you. Never chuck it in the dryer as the filling will become damaged, clumpy and bulky as a result of the heat, plus the dryer isn't environmentally friendly but luckily the sun is! Lay your duvet flat or hang it on your washing line in the shade after washing to let it dry. See the care label for full washing and drying instructions. Unfortunately if you pop your duvet in the dryer and damage the product, it won't be covered by the Koala Warranty.
