Temperature-regulating downtopper/mattress protector made of 100% cotton and coated with Lyocell material on one side, which contains microscopic thermal capsules – a space technology developed by NASA.

The downtopper is filled with European quality down, and you can use it on top of your existing mattress topper to achieve fantastic moisture and temperature-regulation. When you lay on the downtopper, it will feel cool at first. But as it absorbs your body heat, it will start regulating your temperature, cooling you down when you’re hot and providing warmth when you’re cold.

Note that double sizes can be delivered with a 90cm U-split at the top, which is suitable for beds with individual elevation.
