What type/tog duvet do I need? Help me please!

[ApolloandDaphne]

I have a 13.5 tog super king size duvet for my king size bed. It is too warm and heavy for the summer so I have been using a 4.5 tog double duvet for the past few weeks. This means DH can't sleep in our bed as there is not enough duvet for us both. I am sleeping like a dream with this duvet as it is so light and feels barely there.

I plan to buy a lighter super king size duvet tomorrow. What do I need? I run very warm but DH is always colder. The one in the spare room is 10.5 tog I think and DH likes that but I wondered if a 7.5 tog might be better.

What do you folks have? I am open to recommendations.

@RandomMess

separate rooms or even beds are even better than separate duvets

aren’t they just. Especially two king sized beds.

We have a 7 in summer and 13.5 in winter

We wear appropriate PJs in between seasons

You need the silent night yours and mine duvet, that's a half and half one
