The duvet that looks the fullest is not necessarily the one that feels lightest. And a light-feeling duvet can still be warm. Choose the sensation you want underneath, then the shape you want to see on top.
YumeFeel has three distinct directions: Air for a lighter layer, Cloud for a substantial microfiber embrace, and Royal for goose down in two warmth options. All three come with a matching cotton cover. The decision is about feel and warmth, not whether you need to buy another cover to finish the set.
Three questions that untangle the choice
First, do you often push your duvet away because you feel warm? Second, do you enjoy feeling a substantial layer around you, or would you rather notice it less? Third, do you want goose down or a microfiber fill? Royal, Cloud and Air are all made without feathers. Answer those before comparing photographs.
| Duvet | Warmth rating | Fill and construction | Choose it for |
|---|---|---|---|
| Air | 4.5 TOG | 140 g/m² microfiber; quilted boxes | The lowest warmth rating in our range |
| Royal Lightweight | 7.5 TOG | 900+ fill power goose down; baffle boxes | Down feel with less warmth than Royal All Season |
| Cloud | 10.5 TOG | 800 g/m² microfiber; concealed internal support | A very full, substantial feather-free duvet |
| Royal All Season | 12 TOG | 900+ fill power goose down; baffle boxes | Our highest warmth rating, with a down feel |
Loft is the shape; warmth is the insulation
Loft describes how full the filling sits. It gives a bed its rounded silhouette. TOG is a measure of thermal resistance. IDFL's explanation of TOG also notes the limits of a laboratory rating: the way a duvet drapes around a person affects the experience.
That is why we describe Cloud as substantial and Air as lower and quilted. They are deliberately different constructions. Choosing Air does not mean accepting a badly filled Cloud. It means choosing a lighter duvet for a different kind of night.
Fill weight is not the weight of the finished duvet
Grams per square metre tells you how much filling is used across an area. A larger duvet needs more filling even at the same specification. The shell, edges, fastenings and removable cover add weight of their own, so do not read a fill-only figure as the amount you will lift into the washer.
For a King, Air contains about 1 kg of filling and Cloud about 5.7 kg. Royal King contains 805 g of down in Lightweight or 1,012 g in All Season. Those figures help explain the different builds; they are not a controlled comparison of total product weight or pressure on your body.
What 900+ fill power does tell you
Royal's fill power describes the loft of its down under test conditions. IDFL defines fill power around the volume of a specified weight of down. It is a different measurement from TOG and from grams per square metre.
Royal uses Canadian Hutterite white goose down, with 97% down cluster and 3% down fibre, and no feathers. The same 900+ fill power appears in both warmth options. Different amounts of that filling produce two choices; the bigger fill-power number alone would not tell you which one to buy.
Picture an ordinary night
If your room stays warm and you like to sleep with a window closed, start with Air. If you enjoy a generous duvet around your shoulders and do not usually overheat, Cloud is worth considering. If you want goose down, choose between Royal's two ratings according to warmth rather than assuming All Season must suit every month.
Households do not have to choose the same thing for every bed. A warmer upstairs bedroom and a cooler guest room can need different layers. Within one shared bed, two sleepers may still prefer different levels of coverage.
Keep the fit decision separate
Queen, King and California King have the same listed dimensions across the three lines. Changing from Cloud to Air changes the construction and warmth, not the size system. Each set includes a matching cover, with ties that connect to the duvet's loops.
Use the duvet size guide to check coverage, then choose Air, Cloud or Royal for the feel you want. A good match should make both getting into bed and making it in the morning feel easier.
