The king size gives you generous coverage, and the soft filling and cover feel light and gentle to touch. It's non-allergenic, which makes it a practical option for sensitive sleepers, and it's made in the UK with a one-year guarantee for reassurance. The 4.5 tog rating means it stays light and lofty without weighing you down, so you'll wake up feeling rested rather than overheated.

Hello Hayley,
After checking with our supplier, they have advised for the Slumberdown Summer Cool 4.5 Tog Duvet - Single: If you are referring to, the full duvet moving inside a quilt cover. – Lower tog duvets are more likely to move inside a quilt cover as they fill less of the cover. To reduce this you need to purchase a good quality cover, polyester duvet covers can be slipping resulting in the quilt shift inside the cover. If you look for a cotton or polycotton cover because the weight of the fabric is higher it will help the duvet stay in place inside the cover.
However if you mean, the fibre filling being clumpy – All our duvets have several rows of channel stitching to hold the filling in place.
Thank you for using Q & A.
