What tog rating should I use for summer in South Africa?

For summer or hot sleepers, a lightweight layer of 3-5 tog works well. Coastal or humid areas may prefer 3-4.5 tog with a breathable cotton throw.

What is the best duvet layering setup for highveld winters?

For colder highveld nights, we recommend a 7.5 tog mid layer combined with a 10-13.5 tog heavy layer for a combined heavy feel. Remove the heavy layer for shoulder seasons.

Which duvet fill is best for humid coastal areas?

Microfibre and hollowfibre offer quick drying and good value for humid coastal areas. Natural fills like wool and down also breathe well but may take longer to dry.

How can layering duvets help save energy?

Layering allows you to adjust insulation without running a heater all night, reducing the need for electric heating. A breathable base and a mid/heavy layer that you can add or remove help maintain comfort as temperatures change.

Layer, don’t replace

Combine a light and a mid/heavy duvet to cover more seasons and save on heating.

Why layering beats a single tog for South African seasons

South African weather is varied: cool nights on highveld suburbs, damp coastal mornings, and milder winter days in some regions. Rather than buying several single-purpose duvets, we recommend a layering approach: combine lightweight and mid-weight layers so a single bed can be tuned for summer, shoulder seasons and cold snaps. Layering gives flexibility, extends the life of each item and-when used thoughtfully-reduces the need for extra electric heating at night.

Quick tog maths: how layers add up

Tog ratings measure thermal resistance. When you use separate duvet inners or a duvet plus a blanket, their insulating effect is roughly additive. For example, a 4.5 tog plus a 7.5 tog creates a combined feel near 12 tog. In practice trapped air and materials modify that exact number, so we recommend thinking in bands rather than absolutes.

Light layer: ~3-5 tog - summer or hot sleepers.
Mid layer: ~6-8 tog - autumn/ spring and useful as a base for layering.
Heavy layer: ~10-13.5 tog - for cold nights or combined with a mid layer for very cold spells.

What to choose by material

We prioritise breathability and durability. Natural fills like wool and quality down trap air efficiently and breathe well; cotton covers keep things comfortable against the skin. Microfibre and hollowfibre offer good value and quick drying for humid coastal areas. If you want hypoallergenic options, look for labeled synthetic fills or treated natural fills.

If you need a starting point, explore our Duvet inners & pillows selection and pair lightweight inners with a throw from Blankets & throws. These internal links show typical tog ranges and fabrics so you can mix-and-match confidently.

Quick practical tip: keep a lightweight 4.5 tog and a mid-weight 7.5 tog (or a 6 tog + 10 tog combo) on hand. That pair covers most South African seasonal needs while staying compact in storage.

Where layering helps most (real South African scenarios)

Layering is especially useful when rooms change temperature overnight: a Johannesburg house can be warm in the evening and drop 6-8°C by 2am; Durban rooms stay humid and trapping too much insulation can feel clammy; Cape Town coastal homes get chilly breezes but sunny afternoons. Layering lets us adapt without running a heater all night.

Example set-ups

Coastal, humid nights: 3-4.5 tog + breathable cotton throw. Choose quick-drying fibres.
Mixed-season suburban bedroom: 4.5 tog base + 7.5 tog mid - remove the top layer as nights warm.
Colder highveld nights: 7.5 tog + 10-13.5 tog for a combined heavy feel when needed; remove the heavy layer for shoulder seasons.

Layering also makes shared beds easier: give each sleeper a separate top layer (a personal throw or duvet topper) so one person can shed a layer without disturbing the other.

How to build a seasonal layering plan (step-by-step)

Identify your night lows: note the typical coolest indoor night temperature for your bedroom. Layering aims to match that range rather than chase a single tog number.
Pick a breathable base (3-5 tog) and a mid/heavy layer (6-13.5 tog). Use a natural heavier layer (wool or quality down) where possible for better warmth-to-weight ratio.
Store spare layers in breathable bags. Swap the heavy layer in and out as the season changes; keep the base layer on the bed year-round if you like a finished look.

Care, rotation and costs

Rotate layers so each sees regular airing and washing according to care labels. A simple plan: base layers washed monthly, heavier inners aired weekly and washed seasonally. Expect reasonable quality duvet inners to start around R500 and good down or wool options to range from R1 200-R3 000 depending on fill and size; throws and blankets often range R200-R1 500. These are estimates-prices vary by brand and fill.

Layering to save energy

Small behavioural changes combined with good layering reduce the need for electric heating. Rather than running a heater all night, lower the room thermostat slightly and add a heavier layer for the first few hours of sleep; remove it if you overheat. We also encourage insulating behaviours: close curtains at dusk, draught-proof windows and use a rug on cold floors. If you want to compare heating options, you can browse our Heaters shop for supplemental options that work with a layering strategy.

Practical checklist before you buy

Decide which room temperature band you need to cover.
Choose one breathable base layer (3-5 tog) plus one mid/heavy layer (6-13.5 tog).
Match materials to your climate: wool/down for dry cold; microfibre or quick-dry synthetics for humid areas.
Factor in care: ease of washing, allergen labels, and long-term durability.

Real examples we’ve seen work

A student living in a small Bloemfontein flat used a 4.5 tog year-round but added a 7.5 tog on winter nights and saved on nightly heater usage. A family in a Cape Town apartment keeps a lightweight 3.5 tog for summer and a wool 10 tog for winter; children use individual throws so everyone stays comfortable without overheating.

Final checklist for layering success

Start with a breathable base layer.
Choose one versatile mid layer and one heavy layer rather than many single-purpose duvets.
Store and air layers properly; rotate seasonally.
Combine layering with small insulation moves to lower heating needs.
