Does your bed deserve a duvet change? Do you know how often your bed needs a duvet change? The Sleep Council recommends a duvet change every 5 years, depending on the quality of the duvet you are sleeping under.
That said, duvets need washing at least every 6 months. This may mean a trip to the launderette as often a king size duvet will not fit in a standard, domestic washing machine. It is important to keep your duvet clean and free of dust mites particularly for people who suffer from asthma or other respiratory ailments. Another point to consider if that not every sleeping in the same bed like the same type of duvet. The tog rating on a duvet will tell you how warm it will make you feel, on a scale of 1 to 15. 15 is the warmest and usually a 13.5 tog rating is designed for winter sleep and a 4.5 tog for summer.
Some duvets can be attached and detached from each other to give a different tog rating depending on the time of year. If you and your sleeping partner can't agree on a particular rating why not consider a 'split tog' duvet?
Duvets do not last forever and they do lose their 'springiness' and ability to trap air which helps to maintain a comfortable body temperature.
