First of all, the idea of a summer and winter doona might seem like either, a) an indulgence; or b) wasteful – it’s summer, who needs a doona?
It’s not out of the question for overnight temperatures in most major cities in Australia to range from a low as 10 degrees and peak as high as the low thirties. With temperature fluctuations as wide as this, you’re asking a lot from a doona. Compare this to the average temperature range in winter – 5-15 degrees in southern states – and the reasons for seasonal bedding start to make sense.
What’s a Tog?
The industry uses tog as a standard name for measuring the warmth of a doona. Togs are a measure of thermal resistance. Basically, how well it will help retain warmth. For a summer doona, somewhere in the range of 4.5 to 6 tog. To put this into context, the top rating is 13.5
Does the filling matter?
Yes, and no. Typically, natural materials have high insulating properties meaning there is less filling required to achieve the same insulation. Wool is the most dense of the common natural fibres followed by duck and goose down. A synthetic doona will give the same effect with a lighter weight.
A natural fibre will likely last longer, but are on average more expensive.
To increase the lifespan of your doonas, professionally cleaning your natural fibre doonas is the best tip for longevity.
Restorative sleep is one of the most important things we can do for our health and mental function. We’ve all experienced the difficulties of a restless summer night, and the right bed and bedding will put you on the path to the best night’s sleep.
