Start with your room and sleep preference
Think about the room during the hours you actually sleep: heating, air conditioning and seasonal changes may matter more than the temperature outside. Consider the layers you already use and whether you regularly wake feeling too warm or too cool.
Someone who sleeps hot in a heated bedroom may prefer a lighter option even in winter. Someone with a consistently cold room may want more fill. These are starting points for choosing, not tested temperature guarantees.
How the four CloudWeave warmth options compare
Light is the lower-fill choice for warmer rooms and people who prefer less insulation. Medium offers a middle option for milder conditions. Arctic adds fill for colder rooms. Ultimate is the highest-fill option within the corresponding size and product range.
Not every product or market necessarily has the same options. Check the selected variant's fill weight and availability. A warmth name is a label within the range, rather than a universal standard shared by all bedding brands.
Read fill weight, fill power and down content separately
Fill weight tells you how much filling is used. Fill power describes loft under test conditions. Down content describes the composition of the fill. None of these alone specifies how warm every person will feel under the finished duvet.
Compare fill weights within one size first. Do not interpret a King duvet's larger total fill weight as proof that it is a warmer option than a smaller duvet. Follow the product's own size chart and selected configuration.
Can these warmth names be converted to TOG?
This guide does not assign a TOG rating or temperature range to the four options. A measured thermal rating requires suitable product testing; fill weight or a marketing name alone is not enough to calculate it.
If you need help choosing, tell support your market, bed size, usual room conditions and whether you prefer lighter or warmer bedding. Check the published return conditions before ordering, particularly for custom items.
Frequently asked questions
Does goose down always mean a warmer duvet?
Species alone does not determine a finished duvet's warmth. Compare down content, fill power where stated, fill weight, size and construction for the specific products. Choose according to your room and sleep preferences.
Compare goose and duck downWhich CloudWeave warmth option should I choose?
Start with overnight room conditions and whether you sleep hot or cold. Compare fill weights within the same size and product. Light, Medium, Arctic and Ultimate are range labels where offered, not universal TOG ratings or guaranteed temperature ranges.
