We know it can be a little daunting finding and understanding all the information when searching for a product, so we've compiled this handy guide to try and help..


Fill power is an indicator of the quality of the down or feather. The technical part involves measuring the amount of space one ounce of down occupies when allowed to reach it's maximum loft.  This is done by placing down (or feather) in a specially designed transparent measuring cylinder, and calculating the fill-power result in cubic inches - for example  700 in³/oz. Simply speaking, higher the fill-power down is better able to to trap more air, and thus able to provide better insulation; higher fill-power means a plumper duvet or pillow. The fill=power range can be from anywhere above 400  in³/oz all the way up-to around 800  in³/oz.


Tog rating is used to indicate the warmth and insulation provided by a duvet - the higher the tog (and thus usually weight of duvet), the warmer the duvet. Below is an indicator of warmth recommended for different seasons. 

Summer Spring/Autumn Winter All-seasons*
4.5 tog 10.5 tog 13.5 tog 9 tog + 4.5 tog duvet. Can be used individually, or fastened together as one.

It's important to note that tog is only an indicator of warmth. The duvet filling plays a major role in determining insulation - where a down duvet is better at both retaining heat and more breathable than a comparable tog synthetic duvet. Read the fillings section below for more details.


Fillings used in duvets and pillows come in various forms: synthetic (fibres); natural (silk, wool); or down and feather (often a blend of both). Down is perhaps the finest of them all, as it's remarkably insulating and breathable - often resulting in a lighter - yet providing equally, and even superior warmth - than a synthetic equivalent. Synthetic duvets are filled with a man-made fibre, which can be micro- or hollow-fibre, and perhaps even a blend of fibres. Natural duvets are filled with any natural fillings, such as silk, wool, linen etc.

We often get asked which is the 'best' down filling. The answer isn't quite so simple, and various factors can dictate the answer. Canadian down tends to be sought after due to its rarity, and has a consistently high fill power; Hungarian and Siberian are both fine quality down, with Siberian down being associated as being sourced from slightly larger-clustered geese and thus having higher fill-power; our Edelweiss collection is our finest range, and is filled with some of the finest pure down available.


Fabrics and construction of a duvet or pillow can make all the difference. Only pure cotton - a soft and breathable natural fabric - is used across our range of down duvets and pillows. All our down duvets and pillows boast double stitched edges and piped edging for ultimate longevity. Baffle box is a technique of stitching internal square 'pockets' with walls inside the duvet to ensure filling remains in place and prevent down shifting and thus eliminating cold spots. *Do note, the norm for 4.5 tog duvets are to be stitched through (as opposed to internal walls) due to the lower amount of filling used in the duvet.
