Duvet Tog Rating

[bednobs]

I need to get a new duvet for my 8 year old.
Her last one the label has faded and I have no idea of the tog rating.
Is 7.5 warm enough/cool enough for year round do you think?

[AuntPollyGrey]

7.5 is usually classed as a summer duvet with 12.5 -15 as a winter one. I think if you go for a really good quality one 7.5 would be ok with a blanket for if it got a bit chilly in the winter.

[bednobs]

perhaps 10.5 instead then?

[Bobbisox1]

A 7.5 then a nice fleecy throw for those colder nights

[THECORBYLOON]

This is a 10.5 tog + 4.5 tog duvet so you can have 4.5, 10.5 and 15 tog.

Everything depends on whether the space in which one is sleeping is heated or not, whether there is a window open, what the weather is like (temperature and wind), and lastly what the individual's preferences are. The colder the environment and the warmer the person wants to be, the better insulating bedclothes will be required.

Ever since the supposed "Tog" unit of measurement was put together and publicised, I have been trying to obtain a definition for it which describes, in normal units of measurements, the physics that the Tog is supposed to measure. I have established the apparently reliable fact that more togs almost certainly means more insulation and that it is meant to replace standard SI insulation measurements by being a fraction of the standard unit. Beyond that everything is very woolly (no pun intended) and the impression I have is that different manufacturers have a different concept of, say, any given Tog number - there appears to be scope for making it mean whatever suits you. This may be why, to the best of my knowledge, nobody outside the UK uses the Tog and only those who have got to know it in the UK have ever heard of it.

I'd opt for 4.5 Tog at this time of year but 7.5 would probably be OK too.

[Maydup]

We find 4.5 best for summer and 10.5 OK for winter (non heated bedroom) with the option of putting the two together if its really bitterly cold. For myself, I'd find 7.5 neither one thing or another. Too warm at the moment and too light for the winter.

KARL there is a British Standard and the Tog is discussed here,

We find the summer one fine all year round so 7.5 would do us.
Does anyone know what Tog actually means. Rhod Gilbert didn't seem to know in this sketch.

[pastafreak]

I've got an unheated bedroom, and while 10.5 might be warm enough, it's way too heavy and bulky. I have a 4.5 on year round. I add/subtract fluffy throws and use an under bed electric blanket. I've never seen 7.5...I'd try that.

I should have said that where down/feather "duvets" have been in use for hundreds of years, the type of down and total weight of it in the item of bedding is stated. The point being that different downs/feathers have different weight and insulation characteristics, plus they also "breathe" slightly differently although the type of fabric envelope also matters. Of the best down one may only need 1.5kg to serve well in an 18 degree environment but of, say, certain feathers one might need well over double that weight to achieve the same thermal comfort. When it comes to price the best down is most expensive and the price drops for the less efficient down and quite sharply again as soon as you introduce feathers, either as a mix/additive or purely feathers. Natural filling usually lasts much longer satisfactorily than does synthetic filling. Both can usually be washed in a machine at 60 degrees with a mild detergent but the synthetic filling often comes out lumpy but the natural filling fluffs up again once thoroughly dry. What in the end puts natural filling beyond its satisfactory lifespan is that the individual down/feather units break. We have "duvets" which are over 20 years old and still quite serviceable, although we only use them occasionally for visitors, etc. because the ones we now use contain better down.

THECORBYLOON, Actually, the honest truth is that I am aware of the supposed definition but in fact I don't see the point in creating a unit from part of a well known unit - a bit like dividing a metre into 13 parts and calling it a "Toe" ;)

[Arksided]

Having just read the title, Rhod Gilbert sprung to my mind as well. I guessed someone might have posted it.

Sorry I don't know the answer to the OP.

[THECORBYLOON]

KARL, what measurement would you use to replace 7.5 Tog?

[cashier]

Depends on your eight year old. Does she/he prefer to be warm or cool? If the former a 13-15 would be better, but if the latter 10.5 may well do. As others have pointed out a nice fleece or blanket could be put over it to make it a bit warmer.

[bednobs]

I'm not sure what she prefers she just sleeps under what shes got, with ong PJs in the winter, short in the autumn and spring and knickers in summer! no heating in the bedroom, north facing (but in the south)

[Vagus]

7.5 is, for me, too hot from May till October.
We currently have a 1.5 tog on our bed, we have a 4.5 as it gets cooler, but never have more than a 7.5 on the bed, with the option of a fleece blanket to throw on top on really cold nights.
Conversely, a good friend of ours has a 13.5 on her bed all year round.
Duvets are so cheap these days I’d start with a 4.5 and go thicker if needed, or add a fluffy fleece blanket.

[Vagus]

Our bedroom is never heated and we have a window open all year round, all three windows are open at the moment.

[MartinMillar]

I have a 15 tog on all year round and also have an electric blanket for 60% of the year

[alavahalf]

We are using a 1.0 at the moment .. going by the forecast we wont even be using that for the next few days !
7.5 for summer .. it must be something to do with the North South divide ?
