What 4.5 tog is best for

4.5 tog sits at the lighter end of the UK tog scale, and it's the rating most commonly reached for during summer months or by anyone who tends to sleep hot regardless of season. It provides enough warmth to avoid feeling under-covered, without trapping the kind of heat that leads to waking up too warm partway through the night.

Who tends to choose 4.5 tog

Beyond straightforward summer use, 4.5 tog is a common choice for centrally heated bedrooms that run warm regardless of the season, for anyone who naturally runs hot at night, and as a lighter second duvet kept specifically for warmer months while a heavier tog is used the rest of the year.

4.5 tog vs. other lightweight ratings

4.5 tog isn't the only lightweight option on the market — some retailers also stock 2.5 or 3 tog for particularly warm conditions. As a general comparison, 4.5 tog offers a bit more coverage than the very lightest ratings while still staying firmly in summer-weight territory, making it a reasonable middle ground if you're unsure between the very lightest options and something with slightly more warmth.

Pairing 4.5 tog with a seasonal setup

A 4.5 tog duvet works well as the lighter part of a seasonal bedding setup. Use it during warmer months, then swap to a higher tog duvet when temperatures fall. Stoftly duvets are sold separately and are not designed to fasten together, giving you the freedom to choose the exact warmth you prefer for each season.

FAQ

Is 4 tog OK for summer?
Yes, ratings around 4 to 4.5 tog are generally considered summer-weight in the UK, suited to warmer nights without leaving you under-covered.
Is 4.5 tog too thin to feel comfortable?
It's designed to feel light rather than thin. There's enough fill to avoid a flat or papery feel, while staying breathable enough for warm weather use.
Can 4.5 tog be used all year in a warm bedroom?
In a consistently warm, centrally heated room, some people do use 4.5 tog year-round rather than switching seasonally. It comes down to personal preference and how warm your specific bedroom runs.
What's the difference between 4.5 tog and a heavier winter duvet?
The difference is purely in thermal insulation — a heavier tog such as 13.5 or 15 traps significantly more warmth, making it suited to colder conditions where 4.5 tog would likely feel insufficient.
Should I buy 4.5 tog if I sleep hot even in winter?
If you consistently feel too warm regardless of season, a lighter tog like 4.5 can work year-round, particularly paired with breathable bedding and a well-ventilated bedroom.
