Choose the Right Duvet Tog Rating with a Sleep-Style Quiz

Why tog matters more than you think

Tog is a measure of thermal resistance: a higher tog holds more warmth, a lower tog lets heat pass through more easily. But tog alone doesn’t decide comfort - your sleep style, usual body temperature, mattress and bedroom temperature all matter. We built this page around a quick, repeatable quiz you can use to choose a tog rating and explain the practical steps once you know your profile.

Quick quiz: find your sleep-style profile

• Are you a warm or cool sleeper? - Warm (you overheat easily) / Neutral / Cool (you often feel cold).
• How do you sleep? - Light cover (kicks covers off) / Moderate (stays under cover) / Deep (rarely moves).
• What’s your bedroom like? - Naturally cool (south-facing, shaded), Average, or Warm (sunny, poor ventilation).

Score your answers simply: for each question give Warm/Light/Cool-bedroom 1 point, Neutral/Moderate/Average 2 points, Cool/Deep/Warm-bedroom 3 points. Add the points to find your profile: 3-4 = Hot sleeper profile; 5-6 = Balanced profile; 7-9 = Cool sleeper profile. We use those profiles below to recommend tog ranges and layering ideas.

How to interpret tog ranges (short reference)

Feature	Light / Warm-sleeper options	Cool / Deep-sleeper options
Typical tog	4.5 - 7.5 tog (breathable, thin fills)	10.5 - 15 tog (thicker fills or layered)
When to choose	Warm bedrooms, hot sleepers, summer months	Cool bedrooms, cold sleepers, winter months
How we recommend using it	Single lightweight inner or breathable all-season	Layered inners or a single high-tog duvet

Start with your profile: practical tog picks

Once you have your quiz result, follow these simple starting points. They’re designed for South African homes where night temperatures can vary between seasons and rooms.

Hot-sleeper profile (3-4 points)

Choose a low-tog inner - think 4.5 tog or a breathable all-season designed for hot sleepers. Look for hollowfibre or Tencel blends and breathable constructions (baffle boxes with lower fill weight). If you like a little weight, layer a thin blanket over the duvet instead of switching to a higher tog.

If you want to shop, start by browsing our Duvet Inners & Pillows category to compare lightweight options and all-season designs: Duvet Inners & Pillows.

Balanced profile (5-6 points)

A mid-range tog (7.5-10.5 tog) is flexible for most homes. Choose an all-season set (two inners that combine) or a medium tog single that feels comfortable through spring and autumn. If your bedroom is cooler at night, pair a 7.5 tog with a lightweight throw for extra warmth when needed.

Cool-sleeper profile (7-9 points)

Aim for 10.5-15 tog in single duvets for consistent warmth. For the most flexible approach, buy a two-piece all-season set (a lighter inner plus a heavier inner) you can clip or zip together. This helps you adapt without buying separate duvets for each season.

How to choose by sleep situation (real examples)

Here are three South African scenarios we see often, and exactly how we’d pick tog for each:

• Shared bed: one partner heats up easily, the other sleeps cool. Choose a medium tog (7.5-10.5) and use separate blankets or a split duvet strategy (two inners) so each person controls their warmth.
• Apartment bedroom with strong sun in afternoon: the room traps heat. Choose 4.5-7.5 tog in summer and keep a 10.5 tog available for winter; ventilation and a fan can reduce the need for higher tog even in cooler months.
• Room above a garage or a flat roof (tends to be cooler at night): choose 12-15 tog or an all-season pair you can combine for winter.

Measuring real comfort - quick checks to try at home

• Night test: try one week with the chosen tog and note how often you wake feeling too hot or too cold.
• Blanket feel test: if the duvet traps heat but you still want weight, use a breathable 7.5 tog plus a thin cotton blanket.
• Partner compromise test: try separate inners for two weeks; often the small extra cost brings big improvement.

Buying tips and what to check on the label

When you compare products, look beyond the tog number. Check fill type, construction and care instructions. Natural fills (down, feather) often give a different warmth-to-weight ratio than synthetics; synthetics tend to be easier to wash and often cheaper. Stitching style (baffle vs channel) affects evenness of warmth. If you want help browsing, our Bed & Linen pages show compatible covers and sizes: Bed & Linen.

How much to budget (typical South African ranges)

Expect to pay approximately R350-R900 for lightweight inners, R700-R1 500 for reliable mid-range options, and R1 200-R3 500 for premium or natural-fill duvets. Prices vary by brand, size and fill - these are estimate bands to help plan your purchase.

Wrapping up - a simple action plan

• Take the three-question quiz above and note your profile.
• Pick the starting tog range we recommend for that profile and try it for one week.
• If you need flexibility, choose an all-season two-piece set or a medium tog plus a breathable throw.
• Shop categories we mentioned to compare fills and sizes: Duvet Inners & Pillows and Bed & Linen.
