All Seasons Hollowfibre Duvet 4.5 Tog: is 4.5 tog the right weight for you?

16 June 2026

The All Seasons Hollowfibre Duvet 4.5 Tog is one of the beddings we stock at Daffodil Collections. It sits in our Duvets & Quilts range, and this is the short version of what you need to know before you choose a size.

How to choose

A UK bed is built in layers and each one does a different job: a protector to keep the mattress clean, a fitted sheet, a duvet in the right tog for the season, and pillows chosen for how you sleep rather than how they look. Buying a matched set is the easy route; buying the layers separately is how you get a bed that suits you.

Size first, then fibre, then colour. A duvet cover is cut for the DUVET and not for the bed, so a king duvet in a double cover is the most common mistake we see — and the one that is hardest to live with.

The sizes it comes in

UK bed names are consistent between retailers; what is not consistent is the mattress underneath them, so measure yours before ordering. These are the sizes this one is made in, with the mattress each is cut for.

SizeThe mattress it fits
Single90 x 190 cm (3ft x 6ft 3in)
Double135 x 190 cm (4ft 6in x 6ft 3in)
King150 x 200 cm (5ft x 6ft 6in)

If your bed falls between two of these, size up: a fitted sheet that is slightly generous tucks, and one that is slightly tight pulls its corners off in the night.

What the numbers mean

4.5 tog is the duvet's thermal resistance — how much heat it keeps rather than how heavy it feels. As a rule of thumb: 4.5 tog is summer, 9 to 10.5 tog is spring and autumn, and 13.5 tog is winter. A warm bedroom, an electric blanket or a partner who runs hot all push you one step lower than the season suggests.

Looking after it

Hollowfibre is washable at home in a machine big enough to let it move, which for a king usually means a launderette rather than a 7kg drum. Dry it thoroughly with a couple of clean tennis balls to break the clumps up as the filling re-lofts.

Always follow the care label on the item itself where it differs from this — the label knows what is in the fabric, and we would rather you trusted it than us.

For hotels, B&Bs and holiday lets

Bedsheets for hotels and B&Bs are washed at a temperature and a frequency no household matches, so the things that matter are the seams, the elastic and how the colour holds. That is why the hospitality trade buys in quantity and in one colour: a matched stock of quality hotel beddings is what makes a linen cupboard workable.
