How to attach two duvets together using our easy to use duvet fasteners /duvet clips


All season duvets

Our All season duvets are made up of two duvets, a lighter tog duvet (4.5 tog or 2.5 tog) and a warmer tog duvet (9 tog or 4.5 tog). The two duvets can be attached to each other with our duvet fasteners, so that you can create a warmer tog duvet. (Also called a 3 in 1 duvet.)

All our all season duvets come with a full set of 16 fasteners, or 12 fasteners for our single size duvets, plus 3 spare.

We have now updated our duvets with new improved fasteners engineered in Germany.


Can you put two duvets in one cover?

Yes. You can put any two scooms duvets of the same size together in one cover. They are joined together with our cufflink fasteners. 


How to use duvet fasteners

Our duvet fasteners are like duvet cufflinks or poppers; two separate pieces that pull apart and snap together. The easiest way to part them is to push up diagonally on one side of the fastener. You can do this from the middle of the fastener using the duvet material if it's more comfortable.

How to join two duvets together - To fix your two duvets together, lay one on top of the other so that the button holes match, then attach each part of the fastener to the outer sides of each button hole and push/snap the fasteners together. 

We recommend attaching one fastener to each duvet corner and then 3 on each side for double, king and super king size duvets.

The duvet clips are not attached to the duvet so you can remove them and use them with any other duvet combination.


Washing your duvet

We recommend removing your fasteners before washing or laundering your duvet.


Replacement fasteners

All our All season duvets come with a full set of fasteners plus 3 spare fasteners. We provide extra or replacement fasteners with no charge on request.
